I just recognized that gzip does his job right.
But objcopy of all binutils > 2.16.1 has problems during binary copy:
powerpc-linux-objcopy -O binary vmlinux arch/ppc/boot/images/vmlinux.bin
The vmlinux file does look good (what i can see with vi) but the
generated vmlinux.bin file is strange. Windows machines say that the
vmlinux.bin file is > then 3GByte, but linux says 1,5Mbyte. But, I can't
open it with vi...
Anywhay i think binutils > 2.16.1 has some problems with ppc.
Does anyone else use buildroot for ppc405 platform and solved the
problems with actual binutils versions?
cheers!
