These options are not supported in redboot binary files provided in ecos distribution,
and I cannot execute redboot in RAM when I
recompile it.
> you need an import here.
you mean doing: "ecosconfig import hal/arm/sa11x0/assabet/current/misc/redboot_RAM.ecm"
The RAM images generated does not worked with this import. I have also try with the
redboot_ROM.ecm, but I have strange result.
The size of the redboot.bin file is about 1,6MB ???
Here is the result of objdump:
install/bin/redboot.img: file format elf32-littlearm

The only differences with the working redboot.rom are sections .got and .got.plt.
These sections also generate warning during the link: "no memory region specified for
section .got".
What does it mean? The linker store these sections in 0x00000000 and 0x00000008, and
pad with zero until 0x50000000. That the reason
why the .bin file is so big.
I use HardHat CDK 1.2 for cross compilation on a Mandrake 7.2 linux.
Is it a configuration problem ?
Benoit.
