Novice question: Pinebook Pro does boot (does it?) but black screen

[Gert V.]

And success this time! Booting Armbian from SD is working. So the PBP is in working order at the moment. I am curious for the reasons behind why is does work this time where it failed before, it is beyond my comprehension at the moment, but at least I can put my PBP to good use.

The next step is to get the PBP to boot from the emmc. Knowing that Armbian works my plan is to flash Armbian to the emmc with the USB-to-emmc-adapter when that arrives. If that is less reasonable than I think it is, please let me know.

Thanks to anyone who chimed in to help me out here, much appriciated.
