Hi Vagrant! > Just tested this on an rpi3b+ and sometime between u-boot 2021.01 and > 2021.04 rpi-arm64 fails to boot on rpi3b+ ... IWithin my patch series there is one patch to modify a defconfig file. I enhanced that patch meanwhile to check, that lines in the modified defconfig show up in the final .config file. Last weekend I found out that several settings differ. I also updated the raspberry specific defconfigs, but the mismatches still remain. My guess is, that the kernel has problems booting.
