Problem on Mount root - Kernel panic

Carlos
Hello guys! 

I´m having a problem when booting my kernel, shows this message:

Kernel panic - not syncing VFS: Unable to Mount the root unknown blog -
(179,2).

I have tried to create mmcblk0p1, 2 and 3 to create the device, but didnt
fix it... 

I also tryed to add rootdelay=time but dont work too.

I think there is something wrong with my uImage . When i make this image i
used the zImage(zImage_a70) in downloads area in this site (When i use
other zImage file it boots my linux but my TFT screen just stay white
coloured)

Does anyone knows how can i solve this problem? I´m trying to run Xorg in
my arm device.



I´m really sorry for my bad english.
Carlos.
