Correct setup for u-boot and fstab ? Device not booting

[kuleszdl]

What exact message are you getting in uboot? In general, I recommend using a custom extlinux.conf on the boot partition. I've written a tutorial on this which you might be interested in as it covers the same topic (getting vanilla Debian running):

Btw.: Mainline u-boot does work nicely on the H64 model B, however, I had trouble with Ethernet last time I checked (must have been Kernel 5.6 or 5.7 back then). See here for details:
