i have done make menuconfig and / or make dist-clean and so on. build the kernel does not seem the problem. it looks like rpi4 cant boot this. but i have no rpi3 at the moment to test if it runs on it. some days ago i read on a place i cant remember that the boot process on rpi4 is different to the older versions. perhaps this is the goal to fix? ubuntu for example use u-boot on rpi. for me its not clear why they do so, instead of booting the kernel direct?
