[ECOS] Placing binary file into RAM on target

[ECOS] Placing binary file into RAM on target

[Warren Jasper]

Does anybody know of a way to place an arbitrary binary file into
SDRAM on a target if one is running gdb stubs?  I am running a
Intel StrongARM SA1110, and would like to load a program into
FLASH via eCos (as opposed to JTAG via a parallel port with JFLASH).

gdb will only load elf type files, so I guess one option is to convert a
file into "elf" and have the loader put it into memory.  Is there an easy way
to do this or a better way?

Thanks in advance,

echo > foo.c
arm-elf-gcc -c foo.c
arm-elf-objcopy --add-section .loadme=mybinfile foo.o
arm-elf-objcopy --set-section-flags .loadme=alloc,contents,load,data foo.o

Probably anyway :). Close enough for you to work out the rest on your own.

Use RedBoot :-)

This would work.  However, RedBoot is a more flexible option since you have
the ability to relocate [move] the code on the fly, perform checksums, etc.

What problems do you have?

If you can get GDB stubs working on a platform, RedBoot is anout 3 minutes
away...
