Alright... I successfully removed the module from one of my boards, reworked the board so I could put a pullup on IO8, then re-reflowed it. Same result. It's still spitting out "ESP-ROM:esp32c6-20220919" regardless of resetting with IO9 low or high...

I tried running the Adafruit Web-based ESPTool ...

I can't see what you have gpio8 tied to, but it should be held high at boot . gpio8 and 9 are the strapping pins. If you are going to build your own boards, get used to reading the datasheets or you are sure to run into some gotchas.


Well, I modified a bare board as shown below (GPIO pin ...

One more thing: In my design, I'm tying MTMS, IO8, and IO15 together in a net called ALARM and actuating that line with my RTC chip. I don't recall why I tied all of those pins together, but it wasn't a great idea. According to the ESP manual, those are all supposed to float, maybe even relative to ...

Thanks for the reply!
3) When I did get something to come through the serial console, it occasionally spit out the text "01:25:02.490 -> ESP-ROM:esp32c6-20220919", which (according to ChatGPT) I understand to mean that it's stuck in bootloader mode.
It depends. It's the first line it spits out ...

Hi everyone,

I designed a board that uses this ESP32-C6:

and the schematic (regarding IO0, IO9, EN, and a USB-C connector) is exactly the same as the Adafruit Feather ESP32-C6:
