Thanks Matthias for your input. I have the same problem using the raspberrypi4-64 target. On my end, the mere fact of enabling RPI_USE_U_BOOT yields a non-bootable image.
The image I generated/burned can be found here: https://www.dropbox.com/s/6glmmgtx0pcd06t/core-image-base-raspberrypi4-64-20220112004201.rootfs.wic.bz2?dl=0 Thanks a lot. ------------- Jean-Philippe Lebel, ing.
