>Re: [uClinux-dev] Could not run app that compiled by m68k-elf-gcc

Hi,
I download the new binfmt_flat.c and flat.h from cvx.uclinux.org and repleace the old ones. I followed rebuild kernel, it's no problem. So, I uploaded the new kernel image to the RAM of ucDimm and type 'goram' to execute kernel from RAM. The ucDimm is downed before displaying the 'Welcome and login' information.
I could not execute the kernel by using the new binfmt_flat.c, why?
Regards & thanks
Aavan

You kernel does not support the flat format used by the elf tools.
You should be able to replace the following files in your kernel source
with the ones from cvs.uclinux.org:
fs/binfmt_flat.c
include/linux/flat.h
You can get the files on the following links:
http://cvs.uclinux.org/cgi-bin/cvsweb/~checkout~/uClinux-2.0.x/fs/binfmt_flat.c?rev=1.7
http://cvs.uclinux.org/cgi-bin/cvsweb/~checkout~/uClinux-2.0.x/include/linux/flat.h?rev=1.2
I have *NOT* confirmed that this works so you will have to try it and see.
If you have built the tools yourself then you may have built them with the
wrong flat.h file as well, although I don't think they would build with
out the new flat.h.
Cheers,
Davidm
