...that does not look like an error to me?

Re: ESP32-C3 Datasheet Pulse Counter
Thanks for reporting this. I think there's normally a link in the PDF where you can report an issue, but I've taken the liberty to file an internal ticket for you; we'll likely have this fixed in the next revision of the datasheet.

Re: No COM port detected on Custom PCB
If you don't have a COM-port show up, the issue is almost certainly between your PC and the CP2102.

Re: SpifFS, newlib, logging and fprintf
I'm guessing the fact that you're writing to spiffs is the culprit... I can't imagine that that filesystem is intended for high writes like you do, at some point you're just filling up the journal and the filesystem needs to collect garbage.

Re: ESP32-WROOM-32 Module
What SDK do you use? If esp-idf, simply run 'idf.py flash'.

Re: Connecting multiple ESP32 | ESP-NOW | WiFi | RPi
The thing with ESP32s only having one radio is true, indeed, and for some things like BT/BLE, coexistence means the radio needs to switch between BT and WiFi channels. However, WiFi and ESP-Now both use the same protocol, and if you use the same channel for both, there's no switching necessary.

Re: StoreProhibited error when equating two pointers
My point is that you're allocating about 48K of RAM, which is a non-trivial amount. Malloc will fail if you do not have that amount of free RAM and will return a NULL pointer. That guru meditation has all the hallmarks of you trying to dereference a null pointer (specifically EXCVADDR: 0x00000000). ...

Re: Initial flash needed for download boot over internal USB?
Yes, given that you put the chip into download mode by starting with GPIO0 low.

Re: Initial flash needed for download boot over internal USB?
Yes, you can; the ROM contains a driver that can flash the device over USB. You do need a way to be able to put it into download mode by grounding GPIO0, though.
