Hi Stefan, Martin,
Thank you for your suggestions. Switching from .elf to uImage for Wandboard Quad actually did the trick, and now I can observe serial output. This is interesting, bootelf never failed me before.Â
well, that's interesting indeed. Would be interesting to know what the u-boot ELF loader makes different.
But it is good to hear that you can now proceed at least.

Might it be that the u-boot versions differ and therefore the pre-Genode hardware/uart initialization causes troubles with HW?
