I would expect to use second stage booting to be more robust, because a
missing gpio to enable some hardware component in barebox is already
setup by U-Boot.

Do you have a command line for me? I used

	scripts/kwboot -b images/barebox-netgear-rn104-uart.img /dev/ttyUSB0

which took much longer than I expected (didn't time it, but I'd say in
the several minutes range). And I didn't know what to do then. Ctrl-C
and then connecting microcom was wrong. Adding -t to the command line
above, too.

How do you know which phy is used? I assume from Arnaud's webpage?

Any hints how I can debug this apart from using a dtb without pinmuxing
stuff? (OTOH the same dtb works with linux, hmm.)

Best regards
Uwe
