32be_rootfs boot from sdcard (ls1046)
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 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?
ALSA device list:
No soundcards found.
