bootelf command
===============
Synopsis
--------
::
bootelf [-p|-s] [-d <fdt_addr>] [<image_addr> [<arg>]...]
Description
-----------
The *bootelf* command is used to launch a ELF binary at *image_addr*. If
*image_addr* is not specified, the bootelf command will try to find image in
*image_load_addr* variable (*CONFIG\_SYS\_LOAD\_ADDR* by default).
Args after *image_addr* will be passed to application in common *argc*, *argv*
format.
A command sequence to run a ELF image using FDT might look like
::
load mmc 0:1 ${loadaddr} /kernel.elf
load mmc 0:1 ${fdt_addr_r} /soc-board.dtb
bootelf -d ${fdt_addr_r} ${loadaddr} ${loadaddr}
image_addr
Address of the ELF binary.
fdt_addr
Address of the device-tree. This argument in only needed if bootable
application uses FDT that requires additional setup (like /memory node).
arg
Any text arguments for bootable application. This is usually the address
of the device-tree.
Flags:
-p
Load ELF image via program headers.
-s
Load ELF image via section headers.
-d
Setup FDT by address.
Configuration
-------------
The bootelf command is only available if CONFIG_CMD_ELF=y. FDT setup by flag -d
need CONFIG_CMD_ELF_FDT_SETUP=y.
