I installed linux-armv7, but I couldn't ssh to the device after reboot.
Before reboot it said I need to have an updated uboot, not sure if I
have one or not, but that might be why it didn't work. Or who knows?
Maybe will come back to this later. For now I think I've burned enough
cycles on this device order problem.
I've ordered an i2c audio device, will be curious to see if that makes
for better latency than USB, but it probably won't arrive for a few
weeks. From what I understand it should be a good bit faster.
In the meantime I think I'm going to play around with faust, I've had
pretty good luck with that so far.
