[U-Boot] uBoot Scripts BeagleBone Black Yocto

[Benedikt Wiesnet]

Hi everybody,

sorry for asking stupid questions, but you are my last hope for getting this working...

What I would like to do, is embedding this script: https://github.com/rauc/rauc/blob/master/contrib/uboot.sh
Into u-Boot with Yocto: ./mkimage -T script -A arm -C none -n 'Redundant Boot' -d custom.sh custom.img

But I can not get it work according to your manual: https://www.denx.de/wiki/DULG/UBootScripts
