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..

Correct!

Then eMMC won't be even looked at:

<normal> mmc1 mmc0 usart0 usb0

<push/button, P8_43/GND> SPI0 mmc0 usb0 uart0
