I checked my setenv, but can't figured out what's wrong with that ,or does there any problems that I haven't noticed yet?

Please help me out these! Thanks a lot !

Hello,

You could try with another SD Card. Check the card holder on the board as well.

Best Regards,
Margarita

Able to access the "mmcblk0p2" partition of your SD card on PC ?

Try to mention "rootfstype=<type>" in u-boot bootargs.
Ex:
If you formatted the SD card in exte fs then
rootfstype=ext3

Thanks! I have tried your suggestion,but no success...Best Regards

Thanks!
By taking your advice,I mentioned "rootfstype=ext3" in my u-boot bootargs, and in the same time ,
I found a mistake in spelling of "earlyprink",that a "t" was missed!
then file-system was booted successfully!Thank you !

By the way, I have another problem which still need you help, when I tried booting file-system via nfs settings;

Sounds good.

By looking to your bootargs, you are trying to boot with STATIC IP address and not through DHCP but it is expecting and calling DHCP boot.

If you would like to boot with STATIC IP then try the following u-boot env.

Ex:

setenv bootargs mem=32M console=/dev/ttyO2,115200 ip=192.168.1.11:::::eth0:off nfsroot=192.168.1.131:/usr/local/filesystemroot=/dev/nfs rw rootwait
