[meta-freescale] : boot 32be 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.


1.      I 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:

My boot option is :
=> setenv bootcmd "ext2load mmc 0 a0000000 kernel.itb && bootm a0000000"
=> setenv bootargs "root=/dev/mmcblk0p1 rw earlycon=uart8250,0x21c0500 console=ttyS0,115200"
=> boot

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?)

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


2.  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?

=> setenv bootcmd "ext2load mmc 0 a0000000 kernel.itb && bootm a0000000"
=> setenv bootargs "root=/dev/mmcblk0p1 rw earlycon=uart8250,0x21c0500 console=ttyS0,115200"
=> bootm a0000000:kernel at 1 - a0000000:fdt at 1
