I reported already that the prior version that ext4 has issues with
sub-directories. I don't think that has been addressed in V5. Some
directories show up fine and some don't. So it's kind of random whether
u-boot can read a /boot directory. This was after full ubuntu installs.
I'd guess a simple test with a couple of files and directories will not
show the problem.
