Creating an SD for 'dunfell' build.

[gfine1]

After running into a problem with a 'zeus' build we decided to move forward to dunfell. 

The build completed, and then we modified our script to copy this new build to an SD

The script copies the 'Image' to P1 and the setenv is printed as a reminder. 

The error I get is when it looks like its trying to load the kernel.

This script worked for 'zeus' with some small mods. 

What needs to be modified to work for  'dunfell'?

You put rootfs, Linux Kernel and dtb file in /dev/mmcblk0p2, however you used /dev/mmcblk0p1 in bootargs.

Please modify bootargs as the following.

=> setenv bootcmd 'setenv bootargs root=/dev/mmcblk0p2 rw rootdelay=3 console=ttyS0,115200;mmcinfo;ext2load mmc 0:2 0xa0000000 /boot/Image;ext2load mmc 0:2 0xb0000000 /boot/fsl-ls1043a-rdb-sdk.dtb;booti 0xa0000000 - 0xb0000000'
