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).
Thanks!
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.
Yes, this is a known issue which requires an update to uboot-tools. Basically, abc uses the uboot environment variable $console. Currently uboot-tools provides that setting, which includes the right tty, but doesn't set the speed (It should be 115200), so the kernel message output is garbled, probably 9600 baud. Systemd seems to figure out the right setting in the end though.
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.
Long term we'd like to retire abc in favor of extlinux- abc is a stopgap for boards with a uboot which cannot support it. I suggest filing a BZ against uboot-tools for what appears to be missing. Thanks again,
