Given the "no failures to find a boot device", I suggest an experiment of (temporarily?) reverting to the official rpi_arm64_fragment (to disable the U-Boot logging) and seeing how it behaves without the extra messages. The timing changes from the messages could be contributing to some of the behaviors you are seeing. > The > log file is at > http://nemesis.zefox.com/~fbsd/pelorus_console.txt6_more_loops=20 >=20 >> It might not be handy to test lots of examples of >> the "Storage Device(s) found" messages, independent >> of what follows each non-zero one.
