Sample project to test CppUTest for Keil MDK-ARM toolchain and AT91SAM7A3 chip.
Requirements:
1. CYGWIN (rm.exe, mkdir.exe, make.exe)
2. Keil MDK-ARM
3. JLink Flash (for programming chip)
4. serial connection to DBGU interface
5. 4 MHz quartz. If else, need to be adjusted in
$(CPPUTEST_HOME)/platforms_startup/armcc/AT91SAM7A3/SAM7A3.asm
(for setup PLL and change core clock from IRC to PLL)
and
$(CPPUTEST_HOME)/platforms_startup/armcc/AT91SAM7A3/Retarget.c
(for _clock_init() function working correctly)
6. eclipse + gdb server from JLink + arm-none-eabi-gdb from GNU ARM Tools Embedded
For debug only.
First, you need to compile CppUTest and target startup library:
make -C ../../../platforms/armcc
make -C ../../../platforms_startup/armcc/AT91SAM7A3
Second, you need to write tests. As example, I use
$(CPPUTEST_HOME)/examples/AllTests/CircularBufferTest.cpp.
All test from $(CPPUTEST_HOME)/examples/AllTests/ needs to many
RAM (chip does not have such).
Third, you need to make executable:
make all
Fourth, you need to program executable on target chip:
make prog
Project use semihosting, so you may use standard printf() or std::cout << "Hello!"
If problems with heap or low memory, adjust heap size in
$(CPPUTEST_HOME)/platforms_startup/armcc/AT91SAM7A3/SAM7A3.asm
and rebuild startup library.
Startup library uses standard Keil MDK-ARM license.
Eclipse project is tested in eclipse Kepler, eclipse Luna.
You need to adjust some environment variables in "C/C++ Build" tab in
properties window for project.
"CPPUTEST_HOME" is a path to root of CppUTest
"KEIL_DIR" is a path to ARM C/C++ compiler
"PATH" there is need to add path to make.exe
Eclipse project use plugin "GDB Hardware Debugger" to debug, so for debug
you may install "GDB Hardware Debugger" and gdb client (from
GNU ARM Tools Embedded) or create your own debug configuration
(for exampe, use eclipse plugin from Keil MDK-ARM installation; no need to
install other plugins and toolchains).
