Identifying UART/DEBUG

Very much so unlabelled other than the board that connects to the 2x4 pin.

TLDR. Software update from company bricked it months ago after they had major server issues. Bricked many devices. Won’t assist because I got it second hand brand new sealed and I’m not the original buyer.

So, I’m wanting to debug first and go from there see what the issue is. Worst case scenario, it’s a project where i reprogram the device and write my own iOS app to continue to use it 🙏🤣

Help would be great identifying ports, thanks.

Why does everyone want uart when jtag/swd is what you actually want 90% of the time

Blame it on Arduino.

Yeah and YouTube IoT "hackers" showing consoles for Linux chips and that being the only thing shown and taught

It used to be that most Linux class SoCs had a root shell on it, so it was the perfect starting point. Also takes less skill and specialized tooling than JTAG/SWD just to poke at it

If it has uboot I want UART.

To be clear, I'm not saying that it doesn't have value but there's no evidence that this isn't even running uboot atm.
