it looks like the initramfs was empty,

please check if you have files in romfs/bin ?

please check initramfs content as in the wiki page,

which linux distro do you use?

Hi hippo !

yes . I don&#39;t have any file in romfs/bin .

I build kernel on Linux platform . I have 3 file : nios2gcc.tar.bz2 + uClinux-dist-20060803.tar.bz2 + uClinux-dist-200608003-nios2-02.diff.gz and i did step by step in uclinux-dist wiki page .

I think some file is wrong ? is it correct !!!

thanks !
