IMHO extlinux.conf is more debugging friendly.

Boot.scr requires the following command:
mkimage -C none -A arm -T script -d boot.cmd boot.scr

The mkimage utility (BR2_PACKAGE_HOST_UBOOT_TOOLS) is not on the board, 
you need to transfer the converted file over the network. Or reconnect 
the microSD card.
