Yes, it looks like that kwbimage header was refused by the bootroom. Do you have some older U-Boot binary in .kwb format which you can successfully boot? Or are you able to boot that U-Boot binary via some older version of kwboot? I would like to inspect some working setup, so need some U-Boot binary which can be successfully transferred. > The Pogoplug V4 > continued to boot with the image on NAND (U-Boot 2021.04-tld-1).
