Hello,

This is problem is solved, because I have a small sdram(8 M),and I download it with file system, it's quite big for the small sdram, so I tried to just run the fake kernel, then I can see the kernel complain that can not mount a valid root file system, I'm sure it's because the lack of sdram, so I upgrade my board's sdram to 16M(I just can replace to this size), then it works well!

see the result:
