I think it works just fine with bash. As long as the tool is targeted at
bash and not POSIX shell, portability shouldn't be an issue.

Any 3.3V USB-UART bridge should do. I think I'm using a pl2303 at the
moment, but I'm sure any other will work as well.

What you need to connect is only EC_TX <-> RX, EC_RX <-> TX and GND <->
GND. Do not connect the 3.3V rails together!

Yeah that's a good way to go. I've just soldered dupont cables to my
device because I only use it as a dev unit.

What I want to implement next in Origami-EC is charger and battery
support, but I didn't have enough free time to dive into the
implementation of it.

Cheers,
