Hello Everybody,

I have a beagleboard Rev C4 and when I try to load the kernel from memory with bootm command, it shows me an error in the middle of loading kernel. This is the error message:

Waiting 1sec before mounting root device...
mmc0: new high speed SD card at address b368
mmcblk0: mmc0:b368 5     3.83 GiB
 mmcblk0: p1
VFS: Cannot open root device "b302" or unknown-block(179,2)
Please append a correct "root=" boot option; here are the available partitions:
1f00             512 mtdblock0 (driver?)
1f01            1920 mtdblock1 (driver?)
1f02             128 mtdblock2 (driver?)
1f03            4096 mtdblock3 (driver?)
1f04          255488 mtdblock4 (driver?)
b300         4020224 mmcblk0 driver: mmcblk
  b301         4016128 mmcblk0p1
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2)

I changed some environment variables to get result, but it failed with same error.

Could you please help me if you have any idea. Thanks a lot in advance.
