Re: Check if internal flash is busy
That's technically not possible. When writing to flash, code executing from the flash cache isn't available and as such all but the very highest-priority task will be suspended. That should include other tasks that are about to do something to flash. Any chance you can post the error and/or your code?

Re: ESP32S3: RTC main counter interrupt while awake
Why are you messing with the RTC in that way? As the header directory indicates, those functions are private to ESP-IDF; it's very likely that ESP-IDF also uses the RTC for stuff and your code interferes.

Re: SPI DMA crashes when using WiFi
Oooh, if the image data is in flash, that'll trigger this: as flash isn't DMA'able on most chips, the driver needs to copy the thing to RAM first. In theory, it could indeed do this in small chunks, triggering to re-copy on every DMA chunk, but in practice it doesn't do this: it would make the SPI d...

Re: Confuse about esp32 3.3V and 0-30V from electric meter S0 pulse interface
An S0 connector itself does not output a voltage; the levels in that document specify what voltage you can apply to it externally without it breaking. Technically applying 3.3V is outside the specs (it says minimum is 5V) but I imagine it works with most meters anyway.

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.
