sd card rootfs problem

yankz — Mon, 24 Jul 2017 01:06:39 GMT

I have an LS1043ARDB board and I follow the "QorIQ-SDK-2.0-1703-IC-Rev0.pdf" to deploy it. I follow the sector 4.4.7.9.4 and boot from sd card is ok, using kernel at itb file and SD card partition as rootfs.

=> setenv bootargs "root=/dev/mmcblk0p1 rw earlycon=uart8250,0x21c0500 console=ttyS0,115200"

=> ext2load mmc 0 a0000000 kernel.itb && bootm a0000000

Next I tried to use the NOR bank0 boot but let it use the SD card partition as rootfs. The NOR bank0 u-boot bootargs is link this

"bootargs=console=ttyS0,115200 root=/dev/ram0 earlycon=uart8250,0x21c0500,115200"

then I use command

=> setenv bootargs "root=/dev/mmcblk0p1 rw earlycon=uart8250,0x21c0500 console=ttyS0,115200"

=> boot

but the kernel can't recognise SD card partition rootfs and print errors:

[ 4.253800] VFS: Mounted root (ext2 filesystem) on device 1:0.

Is the kernel missing something or I can't do link this?

Try to use u-boot in NOR Flash from the same SDK as kernel and root file system.

Have a great day,
