So I can switch between eMMC and SD card bootmode if I connect a relais? That would be great. So I can in case I see a problem switch to other bootmode and can automate git bisect. Also it would be possible to verify both bootmodes. I have to wait to try this, until Wolfgang is back from vacation, as I have no physical access to the bbb.
