@Cameron-Spitzer said in Is Omega2 usable without a dock?:

Next I need to learn how to control suspend, hibernate, and resume, and take interrupts on I/O pin transitions. Wake from suspend on an I/O pin change would be really nice. That was pretty easy on Raspberry Pi and Arduino (interrupts only), just have to find the docs.

I'm afraid Omega2+ doesn't have suspend, hibernate, ... Power Modes - it can be Power On or Power Off only.

Probably you have already known we have some info about Omega2(+)'s SoC Mediatek MT7688 Datasheet

About GPIO Interrupts:

There isn't any too much progress - I think.
