That's very interesting information. Perhaps because I half understand what you're talking about.
I bought an ARM development board and it exposes the exact same serial console on boot. So many the Arm boards work like this? So I would be looking for two pins on the processor ? I'm up to speed with running a 5v serial line. But aren't those processors a bit lower? as in 2.7v or something? Thanks for the leads. Fantastic.
