Sorry, still nothing.

Re: ADC and accurate timing

If you use the ESP32-C6, you may be able to use the ETM to do a bunch of those things with a fairly high degree of precision. (Although I'm not sure about the support for this in ESP-IDF, you may want to look that up as well.)

Re: Bluetooth options disappeared from menuconfig

Do you have perhaps a custom component which name clashes with one in ESP-IDF?

Re: ESP32H2 module programming

Honestly, the easiest way is to simply incorporate in-circuit flashing into your PCB. The H2 has an USB-serial-JTAG device, so it can be as easy as routing the required pins to a test pad or USB connector, plus making sure GPIO9 is available somewhere so you can ground it to force download mode.

Re: Problem getting back into download mode

GPIO8 needs to be high for the chip to enter download mode - is that the case in your circuit?

Re: ESP32-C6-DevkitM-1: GPIO Allocation

For all these peripherals, you can basically pick any (otherwise unused, and watch the strapping pins) GPIO. These peripherals all can be routed through the GPIO matrix, so they can connect to any pin.

Re: ESP32-C3 power consumption when held in reset

For reference: this is an ESP32-C3-Wroom-02 (containing the same ESP32-C3 chip) when held in reset. I measure the fraction of an uA that I'd expect.

Re: ESP32-C3 power consumption when held in reset

I don't know what to tell you... something is still leaking current somewhere on your design. Might be as simple as a resistive divider, might be something as flakey as slightly-conductive flux residues. For instance, you don't happen to have a pullup on EN that conducts current to ground when you p...

Re: ESP32S2 with CH340F custom board not working

On the USB connector, the CC pins should be connected to a 5.1K pulldown each. If you don't have that, an USB-C-to-USB-C cable won't work; it won't give the board any power. To bypass this issue (for debugging), you can use an USB-A to USB-C cable, that won't have that issue.
