[OE-core] [meta-freescale]: 32be_rootfs boot from sdcard

[Zheng, Ruoqin]

32be_rootfs boot from sdcard (ls1046)

I used source code provided by nxp  QorIQ-Linux-SDK-v2.0-SOURCE.iso + SDK-V2.0-1701 to build the kernel and rootfs , then it can’t boot from sdcard.



I tried to put kernel(32be) and rootfs(32be) in SD card , and boot it follow the SDK2.0, it was fail to mount the rootfs(while 64be kernel is normal),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?)

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

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 at 1 - a0000000:fdt at 1”

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