Ah, the problem with BBB is that it wants to boot from eMMC, not SD,
unless the button is pressed. It's possible, and I'd have to look at
the TRM and maybe the schematic, to see about changing the order, or
being able to remote boot it with a blank eMMC.
The button is routed to the expansion header..
I've got a few hot-wired..
GND: P8_43
Ah, so if I wire P8_43 to ground, the button will always be pressed?
Neat, I need to go try that..
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.
Thanks for this hint!
bye,
Heiko
