I was copying from Ayufan's boot order, I don't actually know.

Hi,
the jumper is the red in place on the following picture.

When in place the rock64 boots from the µSD card, when not in place it boots from the eMMC.
Apparently, the SPI flash memory is correctly programmed, so i did not have to program it.

Looks like a hard drive jumper from here. I wonder if you could make connections to those 2 pins and bring the wires out to a toggle or slide switch on the outside of the case. Or if that would be too much capacitance and inductance. The pins are probably on standard 0.1 inch centers, same as a DIP package, you can probably buy a cable and plug if you look in the right place. Outside of the Pinebook Pro case I mean, I think it has the same jumper arrangement.
