Read Me(SRecord) Read Me(SRecord)
NAME
SRecord - manipulate EPROM load files
DESCRIPTION
The SRecord package is a collection of powerful tools for manipulating
EPROM load files.
I wrote SRecord because when I was looking for programs to manipulate
EPROM load files, I could not find very many. The ones that I could
find only did a few of the things I needed. SRecord is written in C++
and polymorphism is used to provide the file format flexibility and
arbitrary filter chaining. Adding more file formats and filters is
relatively simple.
The File Formats
The SRecord package understands a number of file formats:
Ascii-Hex
The ascii-hex format is understood for both reading and
writing. (Also known as the ascii-space-hex format.)
ASM It is possible, for output only, to produce a serices of DB
statements containing the data. This can be useful for
embedding data into assembler programs. This format cannot be
read.
Atmel Generic
This format is produced by the Atmel AVR assembler. It is
understood for both reading and writing.
BASIC It is possible, for output only, to produce a serices of DATA
statements containing the data. This can be useful for
embedding data into BASIC programs. This format cannot be
read.
Binary Binary files can both be read and written.
B-Record
Files in Freescale Dragonball bootstrap b-record format can be
read and written.
C It is also possible to write a C array declaration which
contains the data. This can be useful when you want to embed
download data into C programs. This format cannot be read.
COE The Xilinx Coefficient File Format (.coe) is understood for
output only.
Cosmac The RCA Cosmac Elf format is understood for both reading and
writing.
DEC Binary
The DEC Binary (XXDP) format is understood for both reading and
writing.
Elektor Monitor (EMON52)
The EMON52 format is understood for both reading and writing.
Fairchild Fairbug
The Fairchild Fairbug format is understood for both reading and
writing.
Formatted Binary
The Formatted Binary format is understood for both reading and
writing.
Four Packed Code (FPC)
The FPC format is understood for both reading and writing.
Hexdump It is possible to get a simple hexdump as output.
IDT/sim The IDT/sim binary file format is understood for both reading
and writing.
Intel The Intel hexadecimal format is understood for both reading and
writing. (Also known as the Intel MCS-86 Object format.)
Intel AOMF
The Intel Absolute Object Module Format (AOMF) is understood
for both reading and writing.
Intel 16
The Intel hexadecimal 16 format is understood for both reading
and writing. (Also known as the INHX16 file format.)
LSI Logic Fast Load
The LSI Logic Fast Load format is understood for both reading
and writing. Logisim The Logisim format is understood for both
reading and writing. See srec_logisim(5) for more information.
Memory Initialization Format
The Memory Initialization Format (.mem) by Lattice
Semiconductor is understood for writing only.
MIF The Memory Initialization File format by Altera is supported
for both reading and writing.
MOS Technology
The MOS Technology hexadecimal format is understood for both
reading and writing.
MIPS-Flash
The MIPS Flash file format is supported for both reading and
writing.
Motorola S-Record
The Motorola hexadecimal S-Record format is understood for both
reading and writing. (Also known as the Exorciser, Exormacs or
Exormax format.)
MsBin The Windows CE Binary Image Data Format is supported both for
reading and writing.
Needham The Needham Electronics ASCII file format is understood for
both reading and writing.
OS65V The Ohio Scientific hexadecimal format is understood for both
reading and writing.
PPB The Stag Prom Programmer binary format is understood for both
reading and writing.
PPX The Stag Prom Programmer hexadecimal format is understood for
both reading and writing.
Signetics
The Signetics format is understood for both reading and
writing.
SPASM The SPASM format is used by a variety of PIC programmers; it is
understood for both reading and writing.
Spectrum
The Spectrum format is understood for both reading and writing.
Tektronix (Extended)
The Tektronix hexadecimal format and the Tektronix Extended
hexadecimal format are both understood for both reading and
writing.
Texas Instruments Tagged
The Texas Instruments Tagged format is understood for both
reading and writing (both 8 and 16 bit). Also known as the TI-
tagged or TI-SDSMAC format.
Texas Instruments ti-txt
The TI-TXT format is understood for reading and writing. This
format is used with the bootstrap loader of the Texas
Instruments MSP430 family of processors.
TRS-80 The Radio Shack TRS-80 object file format is understood for
reading and writing.
VHDL It is possible to write VHDL file. This is only supported for
output.
Verilog VMEM
It is possible to write a Verilog VMEM file suitable for
loading with $readmemh(). This format is supported for reading
and writing.
Wilson The Wilson format is understood for both reading and writing.
This mystery format was added for a mysterious type of EPROM
writer.
The Tools
The primary tools of the package are srec_cat and srec_cmp. All of the
tools understand all of the file formats, and all of the filters.
srec_cat
The srec_cat program may be used to catenate (join) EPROM load
files, or portions of EPROM load files, together. Because it
understands all of the input and output formats, it can also be
used to convert files from one format to another.
srec_cmp
The srec_cmp program may be use to compare EPROM load files, or
portions of EPROM load files, for equality.
srec_info
The srec_info program may be used to print summary information
about EPROM load files.
The Filters
The SRecord package is made more powerful by the concept of input
filters. Wherever an input file may be specified, filters may also be
applied to that input file. The following filters are available:
bit reverse
The bit-reverse filter may be used to reverse the order of bits
in each data byte.
byte swap
The byte swap filter may be used to swap pairs of add and even
bytes.
CRC The various crc filters may be used to insert a CRC into the
data.
checksum
The checksum filters may be used to insert a checksum
into the data. Positive, negative and bit-not checksums
are available, as well as big-endian and little-endian
byte orders.
crop The crop filter may be used to isolate an input address
range, or ranges, and discard the rest.
exclude The exclude filter may be used to exclude an input
address range, or ranges, and keep the rest.
fill The fill filter may be used to fill any holes in the
data with a nominated value.
length The length filter may be used to insert the data length
into the data.
maximum The maximum filter may be used to insert the maximum
data address into the data.
minimum The minimum filter may be used to insert the minimum
data address into the data.
offset The offset filter may be used to offset the address of
data records, both forwards and backwards.
random fill
The random fill filter may be used to fill holes in the
data with random byte values.
split The split filter may be used to split EPROM images for
wide data buses or other memory striping schemes.
unfill The unfill filter may be used to make holes in the data
at bytes with a nominated value.
unsplit The unsplit filter may be reverse the effects of the
split filter.
More than one filter may be applied to each input file.
Different filters may be applied to each input file. All
filters may be applied to all file formats.

RELEASE NOTES
This section details the various features and bug fixes of the
various releases. For excruciating and complete detail, and
also credits for those of you who have generously sent me
suggestions and bug reports, see the etc/CHANGES.* files.
Version 1.64 (2014-Jun-22)
* Cleaned up a few references to the maintainer's name.
* Fixed some warnings in test 38
* Fixed bugs discovered by Mike <russiane39@gmail.com> regarding
the formatting of some of the examples where lines were wrapping
the wrong way.
* Added the ability to compile without libgcrypt if the user
specifies the option --without-gcrypt to configure. If gcrypt is
missing, the user is prompted to either install it or explicitly
compile with it disabled.
* Cleaned up a few recent compiler and doxygen warnings.
* Added Sourceforge Patch #4 contributed by Stas Sergeev
<stsp@sourceforge.net> which contributed get_upper_bound() and
makes it and the lower equivalent public (for use from
libsrecord). Also fixed a bug in srec_memory::find_next_chunk()
where it would fail to reset the find_next_chunk_index once it
became equal to nchunks. After that, find_next_chunk() would
always fail.
* Added prefix and postfix strings to the C Array format which
are applied at each end of the data array declaration. This
allows the user to add various compiler directives such as
location flags or non-standard load address specifiers.
* when converting from AOMF Fixed Sourceforge bug 11 raised by
patryks. In the analysis, it was discovered that a start address
(of zero) was being generated when converting from AOMF. AOMF
does not support the concept of an execution start address.
* The Windows build instructions have been updated by Jens
Heilig <jens@familie-heilig.net>.
* Fixed the length field description in extended tektronix
documentation. The implementation was already correct.
* Added a regression test for calculated address for CRC
(Sourceforge bug 19).
Version 1.63 (2014-Apr-07)
* The srec_tools now understand how to read and write Logisim
formt.
* Daniel Anselmi <danselmi@gmx.ch> fixed a bug with generating
Lattice Memory init files.
* This change set generalises the code that handles redundant
byte settings and contradictory byte settings. The defcon_t type
describes what to do: ignore, warn or error. The --multiple
option is no more.
* Daniel Anselmi <danselmi@gmx.ch> discovered that the "mem"
output format was malformed. The lines now break every "width"
bits.
* Hanspeter Niederstrasser disoverd some false negatives in the
test suite, when used on OSX. Thank you for the bug report.
This has been fixed.
* Simplification of selection code to choose which CRC16
implmentation is used.
* Juliano Mouro Vieira <juliano@utfpr.edu.br> discovered a
problem with the srec_mif.5 description. This mistake is not
present in the code.
* Liju Prasanth Nivas (RBEI/ECA1)
<Liju.PrasanthNivas@in.bosch.com> suggsted another use case for
the examples. In the case of "joining" files that are meant to
be "stacked in layers". Contributions for the examples are
always appreciated. Thank you.
* Added more comments to the code, so that the use of URL_deode
for the command line is better explained. And comment to explain
why not to do turl_encode when building header records.
* Added URL quoting to the command line. There are times you
need to be able to insert unprintable characters on the command
line. The immediate use case prompting this was a user wanting
to put a NUL in the header string. So now you can, as "%00". The
other choice was quoted printable encoding, but that was a bit
obscure.
* Fixed new warnings when building with g++ 4.8.1
* Added more links to the windows files on SourceForge, maybe it
will boost download numbers.
Version 1.62 (2013-Jun-05)
* Luc Steynen <LucSteynen@edna.be> discovered that the -hecksum-
big-endian opion was a counter-intuitive alias for the the
-checksum-bitnot-big-endian option. The -checksum-big-endian
option is now deprecated, in favor of the -checksum-bitnot-
big-endian option; the code will warn uers of the old option
they will need to change. Ditto little-endian variants
* Alin Pilkington <apilkington@moog.com> found that the
Tektronics Extended format was calculating the record length
incorrectory. Thanks you for the bug report. This has been
fixed for both reading and writing.
* Dr. Benedikt Schmitt <Benedikt.Schmitt@safeintrain.de>
suggested being able to inject arbitrary data into the file
header (such as NUL termination characters). This change set
adds URL-style escapes (e.g. %25) to the string on he command
line. For example: -header or -generate -string
Version 1.61 (2013-Jan-04)
* Izzet Ozcelik <izzetozcelik@cscope.co.uk> discovered a bug in
the Tektronix-Extenden format line checksum calculations. The
comparison should have been in 8 bits, not int.
* Daniel Anselmi <danselmi@gmx.ch> contributed a Memory
Initialization Format by Lattice Semiconductor, for output
only.
* Daniel Anselmi <danselmi@gmx.ch> contributed a Xilinx
Coefficient File Format (.coe) output class.
Version 1.60 (2012-May-19)
* There are now several additional CRC-16 polynomials, plus the
ability to select a polynomial by name, rather than by value.
See http://en.wikipedia.org/wiki/Cyclic_redundancy_check for a
table of names and values.
Version 1.59 (2012-Feb-10)
* A number of additional CRC-16 polynomials have been added, as
well as the ability to select a polynomial by name, rather
than by value. See srec_input(1) for more information.
Version 1.58 (2011-Dec-18)
* The -guess command line option, for guessing the file format,
now also tells you the command line option you could have used
instead of -guess for the exact format.
* The Intergated Device Technology (IDT) system integration
manager (IDT/sim) binary format is now understood for both
reading and writing.
* The Stag Prom Programmer binary format is now supported for
both reading and writing.
* The Stag Prom Programer hexadecimal format is now understood
for both reading and writing.
* The MIPS-Flash fiel format is now supported for both reading
and writing.
* Bernhard Weirich <Bernhard.Weirich@riedel.net> discovered that
a backward compatible option had been omitted when the
-INtel_16 option was renamed -INtel_HeX_16 to more closely
match the usual abbreviation (INHX16) for this format. The
backwards compatible option name has been reintroduced.
* The windows build instructions have been greatly imptoved,
based on the experiences of Jens Heilig <jens@familie-
heilig.net> which he has generously shared.
* The documentation in the manual about sequence warnings has
been improved. The -disable-sequence-warnings option must
come before the input file on the command line. My thanks to
Emil Gracic <emil_kruki@yahoo.com> for reporting this problem.
Version 1.57 (2011-Jun-09)
* The byte order of the fletcher16 output has been reversed.
* The meaning of the -address-length option has been change for
the Intel output format. Previously, 2 meant using i16hex
20-bit segmented addressing, and >2 meant using i32hex
extended addressing. This has been changed: a value of 2
requests i8hex 16-bit addressing, a value of 3 requests i16hex
20-bit segment addressing, and a value >=4 requests i32hex
32-bit addressing. My thanks to Stephen R. Phillips
<srp@CSECorporation.com> for reporting the absence of i8hex
support.
* The -generate -repeat-string option is now able to take a
string that looks like a number as the text to be repeated. My
thanks to Stephen R. Phillips <srp@CSECorporation.com> for
reporting this problem.
* Luca Giancristofaro <luca.giancristofaro@prosa.com> discovered
a WinAVR linker that is a sandwich short of a picnic: it
generated non-conforming Intel hex end-of-file records. This
is no longer an error, but only a warning.
* There were some problems with the RPM spec file, these have
been improved. My thanks to Galen Seitz
<galens@seitzassoc.com> for reporting this problem.
Version 1.56 (2010-Sep-15)
* A bug has been fixed in the MsBin output, it now concatenates
records correctly, and calaulate checksums appropriately.
* It is now possible to ask the Fletcher 16 filter to give you a
specific answer, and adjusting the checksum to achieve that
result. It is also possible to specify different seed values
for the sums.
* There is a new srec_cat -enable=optional-address option to
cause output formats capable of omitting addresses, to omit a
leading zero address, as those formats usually default the
address to zero, if no address information is seen before the
first data record. Defaults to false (disabled).
* There is a new srec_cat(1) -output-block-packing option, that
may be used to pack output records even when they cross
internal SRecord boundaries.
* There is a new srec_cat(1) -output-block-size so that you can
specify the block size exactly, rather than implying it with
the line length option.
Version 1.55 (2010-Feb-10)
* The Makefile.in has been improved, it now copes with non-
standard --prefix options.
* The rpm.spec file has been improved, it now separates the
commands, shared libraries and development files.
Version 1.54 (2010-Jan-29)
* There is now a shared library installed, including the
necessary header files so that you can use all of the file
formats and filters in your own projects.
* The license on the shared library code is GNU Lesser General
Public License, version 3.0 or later.
* The code can cope with older versions of GNU Libgcrypt. In
the case of very old versions, by ignoring it.
* A number of build problems have been fixed.
Version 1.53 (2009-Nov-10)
* There is a new MsBin (Windows CE Binary Image Data) file
format, supported for both reading and writing.
* The lintian(1) warning about hyphen in the manual pages has
been silenced, by careful use of -, - and - as appropriate.
Sure makes some of the sources ugly, tho. The lintian(1)
warning about the undefined .XX macro has been silenced, by
making it conditional.
* The code will build without libgcrypt.
Version 1.52 (2009-Sep-17)
* There is a new srec_cat -generator -l-e-constant data
generator (and also -b-e-const) that may be used to insert
multi-byte constants into your data. See srec_input(1) for
more information.
Version 1.51 (2009-Sep-13)
* A number of gcc 4.4 build problems have been fixed.
* A bugs has been fixed in the Intel output format. When using
the segemented format (address-length=2) records that span the
end of segment boundary are tricky. The code now carefully
splits such output records, to ensure the two parts are
explicitly placed into separate segments.
Version 1.50 (2009-Jul-09)
* The CRC16 code has been enhanced to provide low-to-high bit
order, in addition to the previous high-to-low bit order. It
is also possible to specify the polynomial, with the default
the CCITT standard polynomial, as was in the previous code.
See srec_input(1) for more information.
* The MD5, RipeMD-160, SHA1, SHA224, SHA256, SHA384, SHA 512 and
Whirlpool message digests are now supported. See
srec_input(1) for more information.
* There is a new srec_cat -bit-reverse filter, that may be used
to reverse the bits in each data byte. See srec_input(1) for
more information.
Version 1.49 (2009-May-17)
* A typo in the srec_input(1) man page has been fixed.
Version 1.48 (2009-Apr-19)
* There are new Fletcher Checksum filters, both 32-bits and
16-bits, both little-endian and big-endian.
* There are new Adler Checksum filters, both 32-bits and
16-bits, both little-endian and big-endian.
Version 1.47 (2009-Feb-19)
* Memory Initialzation File (MIF) format by Altera is now
supported for reading and writing.
Version 1.46 (2009-Jan-13)
* There is a new option for the --x-e-length filters, they can
now accept a width, and this is divided into the byte lenght,
so that you can insert the length in units of words (2) or
longs (4).
* Some small corrections have been made to the documentation.
* The -minimum and -maximum options have been renamed -minimum-
address and -maximum-address, to avoid a command line grammar
syntax problem.
Version 1.45 (2008-Sep-30)
* A bug has been fixed in the srec_cat(1) command. You are now
able to specify several inputs within parentheses, instead of
just one. This allows filters to be applied to the
concatenation of several inputs.
* The srec_cat(1) command is now able to write FORTH output.
Version 1.44 (2008-Aug-29)
* Some compilers issue a warning when const appears before
extern. "warning: storage class is not first". The C output
has been updated to conform to this expectation.
* The manual page for srec_cat(1) has been enhanced to describe
the in-memory data model, and the resulting output data order.
* The -motorola optional width argument now produces a better
error message when it is out of range.
* The -fill filter now checks the size, and fails for absurdly
large fills, with a -big override if they really want >1GB
fills.
* A bug in the .spec file for rpmbuild has been fixed, it now
takes notice of $RPM_BUILD_ROOT
* There is a new -line-termination option, which may be used to
select the desired line termination of output text files.
Version 1.43 (2008-Jul-06)
* The srec-cat -data-only option has been broken down into four
separate controls. It is now possible to -enable and -disable
individual features, such as "header", "data-count",
"execution-start-address" and "footer". See srec_cat(1) for
more information.
* The srec_cat -start-address option has been renamed
-execution-start-address to remove any confusion with the
-offset filter. The documentation now explicitly explains the
difference between the two.
* Examples of converting to and from binary files have been
added to the srec_examples(1) man page.
* A bug has been fixed in the MOS Tech format, it now emits an
end record even when there is no execution start address
passed in.
Version 1.42 (2008-Jun-01)
* The MOS Technology format was not reading and writing end
records correctly, this has been fixed. The name of the
company has been corrected.
* Some examples of how to insert constant or scripted data into
your EPROM load files have been added to the srec_examples(1)
man page.
Version 1.41 (2008-May-12)
* False negative being reported by tests on Cygwin have been
fixed.
* There are six new filters (-be-exclusive-length, -le-
exclusive-length, -be-exclusive-maximum, -le-exclusive-
maximum, -be-exclusive-minimum and -le-exclusive-minimum)
which are very similar to their non-exclusive equivalents,
except that they do not include the adress range covered by
their output in their output.
* A bug has been fixed in the C word-array output. It was
getting offsets and lengths wrong in some cases.
* A bug has been fixed in the generated C array header file, it
no longer omits the section descriptor arrays.
* A problem with building RPM packages with the names of the
executables in the .spec file has been fixed, and the
BuildRequires has been updated.
Version 1.40 (2008-Mar-13)
* An RPM build problem has been fixed.
* The dependency on the Boost library is now documented in the
BUILDING file.
* Some build problems with g++ 4.3 have been fixed
* A bug has been fixed in the calculation of ranges on the
command line, it no longer goes into an infinite loop for
"-fill 0xFF -over { foo.hex -exclude -within foo.hex }"
construct, which should have been calculating an empty fill
set, but was instead calculating a 4GB fill set.
* The CRC32 filters now take an -xmodem option, to use an
xmodem-like (all bit zero) initial state, rather than the
default CCITT (all bits on) initial state.
Version 1.39 (2008-Feb-04)
* A bug has been fixed in the use of parentheses to group
filters and override the default precedences.
Version 1.38 (2008-Jan-14)
* The CRC16 filters now support a -Broken option, to perform a
common-but-broken CRC16 calculation, in addition to the CCITT
and XMODEM calculations.
* A link has been added to the CRC16 man page section to the
www.joegeluso.com/software/articles/ccitt.htm web page, to
explain the difficulties in seeding CRC16 calculations.
* A buglet has been fixed in the srec_motorola(5) man page, it
now includes S6 in the list of things that can appear in the
type field.
* The ability to negate expressions is now mentioned in the
srec_examples(1) man page.
Version 1.37 (2007-Oct-29)
* It is now possible to have negative expressions on the command
line, to facilitate "--offset - -minimum foo" usages.
* The srec_cat(1) command now has a simple hexadecimal dump
output format.
* The use of uudecode(1) in the tests has been removed, so
sharutils is no longer a build dependency.
Version 1.36 (2007-Aug-07)
* A bug has been fixed in the CRC-16 CCITT calculation; the
algorithm was correct but the start value was incorrect,
leading to incorrect results.
* The CRC16 filters have a new --no-augment option, to omit the
16 zero bits augmenting the message. This is not CCITT
standard conforming, but some implementations do this.
* A problem has been fixed in the generated Makefile.in file
found in the tarball.
* The license has been changed to GNU GPL version 3.
Version 1.35 (2007-Jun-23)
* A major build problem with the generated makefile has been
fixed.
Version 1.34 (2007-Jun-22)
* The C and ASM output formats have been improved in the word
mode.
* Several build problems have been fixed.
Version 1.33 (2007-May-18)
* More examples have been added to the documentation.
* It is now possible to perform set intersection and set
difference on address ranges on the command line.
* There is a new category of data source: generators. You can
generate constant data, random data and repeating data.
* The assembler and C-Array outputs now support additional
options to facilitate MSP430 systems. They can also
optionally write shorts rather than bytes.
* You can now round address ranges on the command line to be
whole multiples of a number of bytes.
Version 1.32 (2007-Apr-24)
* The TI-TXT format output has been improved; it is less spec
conforming but more reality conforming. It now allows odd
alignment without padding. It also ends with a q instead of a
Q.
* The warning for odd input addresses has been dropped. The
spec didn't like them, but the MSP430 handles them without a
hiccup.
Version 1.31 (2007-Apr-03)
* The Verilog format now suppresses comments when you specify
the --data-only option.
* The Texas Instruments ti-txt (MSP430) format is now understood
for reading and writing.
Version 1.30 (2007-Mar-21)
* The ascii-hex output format has been improved.
* The ti-tagged 16-bit format is now understood for reading and
writing.
* The Intel format no longer warns about missing optional
records.
* A bug in the ti-tagged format has been fixed, it now
understands the '0' tag.
Version 1.29 (2007-Mar-13)
* A serious bug has been fixed in the generated Makefile.
Version 1.28 (2007-Mar-08)
* It is now possible to read and write files in the Freescale
MC68EZ328 Dragonball bootstrap b-record format
Version 1.27 (2006-Dec-21)
* [SourceForge Feature Request 1597637] There is a new warning
issued when input data records are not in strictly ascending
address order. There is a new command line option to silence
the warning.
* [SourceForge Feature Request 1592348] The command line
processing of all srecord commands now understands @file
command line options, filled with additional space separated
strings witch will be treated as of they were command line
options. This gets around absurdly short command line length
limits in some operating systems.
Version 1.26 (2006-May-26)
* It is now possible to place parentheses on the command line in
more places to clarify your intent.
* This change prepares SRecord for the next public release.
Version 1.25 (2006-May-18)
* The assembler output has been enhanced to produce ORG
directives, if necessary, to change the data address.
* The srec_cat(1) command now only writes an execution start
address into the output if there was an execution start
address present in the input.
Version 1.24 (2006-Mar-08)
* Additional information has been added to the lseek error when
they try to seek to addresses >= 2**31
* The CRC 16 filters have been enhanced to accept an argument to
specify whether CCITT or XMODEM calculations are to be
performed.
Version 1.23 (2005-Sep-23)
* A segfault has been fixed on x86_64 when running the
regression test suite.
* A compile problem with the lib/srec/output/file/c.cc file has
been fixed.
Version 1.22 (2005-Aug-12)
* The -byte-swap filter now has an optional width argument, to
specify the address width to swap. The default is two bytes.
* The motorola file format now accepts an additional 'width'
command line argument, so you can have 16-bit and 32-bit
address multiples.
* A bug has been fixed in the VMEM output format. It was failing
to correctly set the next address in some cases. This fixes
SourceForge bug 1119786.
* The -C-Array output format now uses the const keyword by
default, you can turn it off with the -no-const option. The
-C-Array output format can now generate an additional include
file if you use the -INClude option. This answers SourceForge
feature request 942132.
* A fix for the "undefined symbols" problem when using g++ 3.x
on Cygwin and MacOsX has been added to the ./configure script.
* There is a new -ignore-checksum command line option. The
-ignore-checksums option may be used to disable checksum
validation of input files, for those formats which have
checksums at all. Note that the checksum values are still
read in and parsed (so it is still an error if they are
missing) but their values are not checked.
Version 1.21 (2005-Feb-07)
* More Doxygen comments have been added to the class header
files.
* There is a new srec_cat --crlf option, which may be used for
force CRLF output on operating systems which don't use that
style of line termination.
* A number of problems with GCC, particularly with the early 3.x
series.
* There is a new "Stewie" format, an undocumented format loosely
based on the Motorola S-Record format, apparently used in
mobile phones. More information would be most welcome.
* A number of build problems have been fixed.
Version 1.20 (2004-Feb-08)
* The AOMF format now accepts (and ignores) more record types.
Version 1.19 (2004-Jan-03)
* It is now possible to set the execution start address in the
output using the srec_cat -Execution_Start_Address command
line option.
* The Intel Absolute Object Module Format (AOMF) is now
supported for reading and writing.
* There is a new srec_cat -Random_Fill filter, like the srec_cat
-Fill filter except that it uses random values.
Version 1.18 (2004-Jan-01)
* The VMEM format is now able to output data for 64 and 128 bits
wide memories.
* A bug in the SRecord reference manuals has been fixed; the
CRCxx had a copy-and-paste glitch and always said big-endian
where little endian was intended half the time.
Version 1.17 (2003-Oct-12)
* There is now support for Intel Extended Segment addressing
output, via the --address-length=2 option.
* There is now support for output of Verilog VMEM format. See
srec_vmem(5) for more information.
* There is now support for reading and writing the INHX16
format, used in various PIC programmers. It looks just like
the Intel Hex format, except that the bytes counts and the
addresses refer to words (hi,lo) rather than bytes. See
srec_intel16(5) for more information.
Version 1.16 (2003-Jul-28)
* Some updates have been made to cope with GCC 3.2
Version 1.15 (2003-Jun-16)
* The ASCII-Hex implementation is now slightly more complete. I
still haven't found a definitive description.
* The Fairchild Fairbug format has been added for reading and
writing. See srec_fairchild(5) for more information.
* The Spectrum format has been added for reading and writing.
See srec_spectrum(5) for more information.
* The Formatted Binary format has been added for reading and
writing. See srec_formatted_binary(5) for more information.
* The RCA Cosmac Elf format has been added for reading and
writing. See srec_cosmac(5) for more information.
* The Needham EMP programmer format has been added for reading
and writing. See srec_needham(5) for more information.
Version 1.14 (2003-Mar-11)
* Numerous fixes have been made to header handling. It is now
possible to specify an empty header with the -header command
line option.
* Some more GCC 3.2 build problems have been fixed.
Version 1.13 (2003-Feb-05)
* Bugs have been fixed in the Texas Instruments Tagged and VHDL
formats, which produced inconsistent output.
* A couple of build problems have been fixed.
* There are two new output formats for ASM and BASIC.
Version 1.12 (2002-Dec-06)
* It is now possible to put -minimum input.spec (also -maximum
and -length) almost anywhere on the command line that you can
put a number. It allows, for example, the -offset value to be
calculated from the maximum of the previous file. The values
calculated by -Minimum, -Maximum and -Length may also be
rounded to arbitrary boundaries, using -Round_Down,
-Round_Nearest and -Round_Up.
* The malformed Motorola S5 records output by the Green Hills
tool chain are now understood.
Version 1.11 (2002-Oct-21)
* The Ohio Scientific OS65V audio tape format has been added for
reading and writing. See srec_os65v(5) for more information.
* Some build problems have been fixed.
Version 1.10 (2002-Jun-14)
* The Intel format now emits the redundant extended linear
address record at the start of the file; some loaders couldn't
cope without it.
* The Binary format now copes with writing to pipes.
* The Motorola format now understands the S6 (24-bit data record
count) records for reading and writing.
* The DEC Binary format now works correctly on Windows machines.
* The LSI Logic Fast Load format is now understood for both
reading and writing. See srec_fastload(5) for more
information.
Version 1.9 (2001-Nov-27)
* The DEC Binary (XXDP) format is now understood for both
reading and writing. See srec_dec_binary(5) for more
information.
* The Elektor Monitor (EMON52) format is now understood for both
reading and writing. See srec_emon52(5) for more information.
* The Signetics format is now understood for both reading and
writing. See srec_signetics(5) for more information.
* The Four Packed Code (FPC) format is now understood for both
reading and writing. See srec_fpc(5) for more information.
* Wherever possible, header data is now passed through by
srec_cat(1). There is also a new srec_cat -header option, so
that you can set the header comment from the command line.
* The Atmel Generic format for Atmel AVR programmers is now
understood for both reading and writing. See
srec_atmel_generic(5) for more information.
* The handling of termination records has been improved. It
caused problems for a number of filters, including the -fill
filter.
* A bug has been fixed in the checksum calculations for the
Tektronix format.
* There is a new SPASM format for PIC programmers. See
srec_spasm(5) for more information.
Version 1.8 (2001-Apr-20)
* There is a new "unfill" filter, which may be used to perform
the reverse effect of the "fill" filter.
* There is a new bit-wise NOT filter, which may be used to
invert the data.
* A couple of bugs have been fixed in the CRC filters.
Version 1.7 (2001-Mar-19)
* The documentation is now in PDF format. This was in order to
make it more accessible to a wider range of people.
* There is a new srec_cat --address-length option, so that you
can set the length of the address fields in the output file.
For example, if you always want S3 data records in a Motorola
hex file, use the --address-length=4 option. This helps when
talking to brain-dead EPROM programmers which do not fully
implement the format specification.
* There is a new --multiple option to the commands, which
permits an input file to contain multiple (contradictory)
values for some memory locations. The last value in the file
will be used.
* A problem has been fixed which stopped SRecord from building
under Cygwin.
* A bug has been fixed in the C array output. It used to
generate invalid output when the input had holes in the data.
Version 1.6 (2000-Dec-03)
* A bug has been fixed in the C array output. (Holes in the
input caused an invalid C file to be produced.)
* There is are new CRC input filters, both 16-bit and 32-bit,
both big and little endian. See srec_cat(1) for more
information.
* There is a new VHDL output format.
* There are new checksum filters: in addition to the existing
one's complement (bit not) checksum filter, there are now
negative and positive checksum filters. See srec_cat(1) for
more information.
* The checksum filters are now able to sum over 16-bit and
32-bit values, in addition to the existing byte sums.
* The srec_cmp program now has a --verbose option, which gives
more information about how the two inputs differ. See
srec_cmp(1) for more information.
Version 1.5 (2000-Mar-06)
* There is now a command line option to guess the input file
format; all of the tools understand this option.
* The "MOS Technologies" file format is now understood for
reading and writing. See srec_mos_tech(5) for more
information.
* The "Tektronix Extended" file format is now understood for
reading and writing. See srec_tektronix_extended(5) for more
information.
* The "Texas Instruments Tagged" file format is now understood
for reading and writing. (Also known as the TI-Tagged or
SDSMAC format.) See srec_ti_tagged(5) for more information.
* The "ascii-hex" file format is now understood for reading and
writing. (Also known as the ascii-space-hex format.) See
srec_ascii_hex(5) for more information.
* There is a new byte swap input filter, allowing pairs of odd
and even input bytes to be swapped. See srec_cat(1) for more
information.
* The "wilson" file format is now understood for reading and
writing. This mystery format was added for a mysterious type
of EPROM writer. See srec_wilson(5) for more information.
* The srec_cat program now has a -data-only option, which
suppresses all output except for the data records. This helps
when talking to brain-dead EPROM programmers which barf at
anything but data. See srec_cat(1) for more information.
* There is a new -Line-Length option for the srec_cat program,
allowing you to specify the maximum width of output lines.
See srec_cat(1) for more information.
Version 1.4 (2000-Jan-13)
* SRecord can now cope with CRLF sequences in Unix files. This
was unfortunately common where the file was generated on a PC,
but SRecord was being used on Unix.
Version 1.3 (1999-May-12)
* A bug has been fixed which would cause the crop and exclude
filters to dump core sometimes.
* A bug has been fixed where binary files were handled
incorrectly on Windows NT (actually, any system in which text
files aren't the same as binary files).
* There are three new data filters. The --OR filter, which may
be used to bit-wise OR a value to each data byte; the --AND
filter, which may be used to bit-wise AND a value to each data
byte; and the --eXclusive-OR filter, which may be used to bit-
wise XOR a value to each data byte. See srec_cat(1) for more
information.
Version 1.2 (1998-Nov-04)
* This release includes file format man pages. The web page
also includes a PostScript reference manual, containing all of
the man pages.
* The Intel hex format now has full 32-bit support. See
srec_intel(5) for more information.
* The Tektronix hex format is now supported (only the 16-bit
version, Extended Tektronix hex is not yet supported). See
srec_tektronix(5) for more information.
* There is a new split filter, useful for wide data buses and
memory striping, and a complementary unsplit filter to reverse
it. See srec_cat(1) for more information.
Version 1.1 (1998-Mar-22)
First public release.
