I am happy to test, but indeed the Wandboard in RC2 uses extlinux. When
booting it shows a uboot menu (with "U-Boot console" as only entry which
autoboots).
Manually loading the boot.scr and running it shows a-b-c and starts the
kernel successfully. Boot log attached. Unfortunately, there seems to be
one issue that the serial output after "Starting kernel..." is messed
up. It only seems to be something binary, so maybe the console
parameters are wrong. I'll try to have a look at that an other day.
It is not clear to me what the advised/correct way to configure the
system should be. Is booting with extlinux the goal, or use a-b-c?
Either way, the uboot.imx that is compiled for the Wandboard does not
seem to have the correct autoboot options. This is probably a bug in the
configuration done by the uboot-tools package, but without knowing what
the expected/planned behaviour is, I can not patch/test or file a decent
bug.
Thanks,
Niels
