I tried to put kernel and rootfs in SD card , and boot it follow the SDK note(ls1046), it was fail to mount the rootfs(while 64be kernel is good),and here is part of log:

mmcblk0: mmc0:0007 SL32G 29.0 GiB

 mcblk0: p1

VFS: Mounted root (ext2 filesystem) on device 1:0.

VFS: Cannot open root device "mmcblk0p1" or unknown-block(0,0): error -6

Please append a correct "root=" boot option; here are the available partitions:

0100          262144 ram0  (driver?)

0101          262144 ram1  (driver?)

0102          262144 ram2  (driver?)

0103          262144 ram3  (driver?)

0104          262144 ram4  (driver?)

0105          262144 ram5  (driver?)

0106          262144 ram6  (driver?)

0107          262144 ram7  (driver?)

1f00          524288 mtdblock0  (driver?)

b300        30375936 mmcblk0  driver: mmcblk

  b301        30371936 mmcblk0p1 00000000-01

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.1.30-rt34+ #2

Hardware name: Freescale LAYERSCAPE

 

The entire log is in atachments, do anyone have any idea about this problem? 

 

By the way, I tried to boot the kernel with command “bootm a0000000:kernel@1 - a0000000:fdt@1”

And the log show as below, you can see that mmcblk0 device is missed, do anyone know the reason?

 

ALSA device list:

  No soundcards found.
