Hmm. Another common pitfall is a floating point mismatch between your kernel and your toolchain, but that one seems to be set correctly in your case as well. I'm afraid I can't provide a quick solution for you at this point, but there are still some more things to consider. - make sure you clean your buildroot tree properly after you changed low level settings like the ones discussed. Maybe you're just stuck on an old version of anything and br2 failed to rebuild the right bits. - set CONFIG_DEBUG_USER in your kernel config and pass user_debug=255 on startup. That will output more details when user space binaries crash. - Consider using gcc 4.3.2 for your tests. I've never used a newer version for ARMs, so I can't prove that this is working. - Try compiling a very simple program which just echos some text and cross-compile it for your target. Use the kernel's init= option to call it and see if it works. If you manage to solve your problems, post your findings here for others, please :) Daniel
