What other hardware did you connect to the ESP32? I suspect whatever you connected is out-of-spec for the ESP32 GPIO pins, blowing it up at a certain point.

Please look at and follow the hardware design guidelines for that chip. At the very least, VDD3P3 is not connected to 3.3V and you're missing a RC circuit on your reset pin.

You have to flash something to it first. A new chip does not enable USB out of the box. I ran into this very same issue on my new boards. That is not true; USB is in the bootloader and when you go into download mode, the chip will respond over USB regardless of what's in the flash. The thing is tha...

Ah, gotcha. Hm, not sure if I have any advice then: standard GPIO isn't too fast on the ESP32 series, 'fast' GPIO doesn't have enough pins, and I don't think the camera interface (which can be abused to read in parallel data) has enough I/O for that. Maybe if you cut a few bits from your address bus...

I found ESP32 C6 but it cannot be used as an AP.

What made you think that?

I had this issue with just 1 esp32 wroom dev board. It was the only board I have seen with that issue after using dozens of esp32 wroom boards. The fix was fairly simple and seems to be reliable. The unit has been powered down/up dozens of times in the last few days. Just bridge the vin (5V) to GPI...

I believe the way SecureBoot works is that you first flash everything to your ESP unencrypted, then on first boot the bootloader will encrypt everything that needs encrypting; as such, you can probably flash your (unencrypted) NVS stuff in the same command line as you flash your (unencrypted) main p...

For reference, on other Posix OSses, you'd do it by running stat() on the directory where the filesystem is mounted. Potentially newlib has the same convention.

You probably want to remove C42.

Generally, ESP-IDF panics whenever it finds a situation that Should Never Happen. There's a fair few things that generate this; just knowing that there was a panic is unlikely to get you to the root cause.
