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

U-Boot 2017.01-dirty (Mar 24 2018 - 19:23:46 +0000) CPU : AM335X-GP rev 2.1 I2C: ready DRAM: 512 MiB MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1 ** First descriptor is NOT a primary desc on 1:1 ** *** Warning - bad CRC, using default environment <ethaddr> not set. Validating first E-fuse MAC Net: cpsw, usb_ether Press SPACE to abort autoboot in 2 seconds => fatload mmc 0:1 100000 /custom.img reading /custom.img 1335 bytes read in 6 ms (216.8 KiB/s) => imi 100000 ## Checking Image at 00100000 ... Unknown image format!

Do you have any hint for me please?

Regards
