P2041RDB-PC USB Boot Kernel Panic

gopikrishnan — Tue, 23 Jun 2015 11:04:56 GMT

I was trying to boot my entire system from USB Flash disk. Installed SDK QorIQ-

SDK-V1.8-20150619-yocto.

I built image for P2041RDB using

$ bitbake fsl-image-full

Under tmp/deploy/images/p2041rdb/

I copied

1) uImage--3.12-r0-p2041rdb-20150623072158.bin -> /flash_disk/uImage.bin

2) uImage--3.12-r0-p2041rdb-20150623072158.dtb -> /flash_disk/uImage.dtb

3) Extracted fsl-image-full-p2041rdb.tar.gz -> /flash_disk/

On u-boot of P2041RDB-PC board

=> usb start

=> fatload usb 0:0 $loadaddr img/uImage.bin

=> fatload usb 0:0 $fdtaddr img/uImage.dtb

=> setenv usbboot setenv bootargs root=/dev/sdb rw rootdelay=5

console=$consoledev,$baudrate $othbootargs;bootm $loadaddr - $fdtaddr

=> run usbboot

But endup with kernel painc error Attachment: "err_in_boot.txt"

Please note that, I tried both root=/dev/sdb and root=/dev/sdb1. The flash disk is not partitioned. So probably root=/dev/sdb would be correct. and the disk was formatted using vFAT filesystem Please correct If I was wrong.

Thanks in Advance,

The small mistake I did, I must have used ext2fs

=> usb start

=> ext2load usb 0:0 $loadaddr img/uImage.bin

=> ext2load usb 0:0 $fdtaddr img/uImage.dtb

=> setenv usbboot "setenv bootargs root=/dev/sdb rw rootdelay=5 console=$consoledev,$baudrate $othbootargs;bootm $loadaddr - $fdtaddr"

=> run usbboot

Remember to format flash disk using mkfs.ext2 /dev/sdb1 before deploying root file system.
