hello,
during the configuration of uClinux I choose GDB/ARMulator as the target.
after that, I install the GDB/ARMulator
so i should carry out : ln -s images/romfs.img boot.rom
I didn't find romfs.img in this directory.So I searched it in uClinux under
user\lib .......
after that, I execute arm-elf-run linux-2.4.X/linux
because arm-elf-gdb linux-2.4.X/linux doesn't work
here the out put of arm-elf-run linux-2.4.X/linux :
