Re: help troubleshooting ESP32-C3 board

CHIP_EN MUST be driven high by your board. If it's not high, you must figure that out first. Normally, that's a pretty simple circuit (a pull-up resistor, and probably a reset switch). If that pin is not at 3.3V, nothing is going to work.

Re: ESP32-C3 - Duplicate UART Tx Data

Ah, well, turned out to be an issue between the ESP32 and our secondary MCU, fundamentally caused by pre-emption of my task causing an unexpected timeout on the secondary side. Thanks for looking, but there's no problem here.

Not that I know of.
I know your pain, and have thought that this would be an excellent addition to 'C', especially in the embedded world, but sadly that's unlikely to happen.

Re: ESP32-C3 - Duplicate UART Tx Data

If I can't figure out a workaround, I'll do that. Trying to avoid it because it's probably a days worth of work, but I understand that sometimes that's the only way. I was hoping that someone could say "Oh, yeah, we see that all the time and the workaround is....". But I was hoping that my lottery t...

ESP32-C3 - Duplicate UART Tx Data

Sorry if this has been asked before, but searching the forum fails with a 500 error code, and my normal backup of using Google search of the site didn't find anything. What I have: ESP32-C3, ESP-IDF 5.1, ESP-Matter 1.1 What I'm trying to do: Use the ESP32 UART port to reflash a secondary MCU. What I...
