You can give this a try: https://github.com/boarchuz/bo_cflash I've only used it with ESP32, in VS Code, and likely with a different IDF version to yours, so expect some obstacles. Anyway, if it works, it allows you to select the app partition you want to flash to and optionally update ota_data at t...

Check Appendix A of the datasheet, where GPIO21 is one of the pins that has pullup enabled at (but not after) reset.

Please pay attention on the second code, I used memset().

You did for esp_http_client_config_t but not for the esp_https_ota_config_t.

The red squiggles are courtesy of Intellisense, not the build process. Ideally the errors from both would be the same, but as you can see if there's any issue with the Intellisense configuration then you can get these annoying red herrings. The build output contains your actual error. In this case, ...

Minimum NVS partition size is 0x3000b, so the inconsistent results you're seeing would fall under "undefined behaviour".

Is mynvs == false with the custom 0x2000 partition? If not, an issue on the esp32-arduino repo is probably the best way to have this addressed.

Debug exception reason: Stack canary watchpoint triggered (loopTask) You'll need to increase loopTask's stack size. This is the task that Arduino creates to run your code, ie. setup() and loop(). I don't know if there's an easy way to do that, so it might be easiest (at least for the purposes of te...

He's right, put a "fflush(stdout);" in there.

I've got in the habit of adding ESP-IDF as a git submodule to every project. There are a lot of advantages, and it only takes a few seconds to set up a new project once you're used to it. I have a template project with git intialised and IDF added, but no commits yet, copy the directory and rename i...

Unfortunately the ESP32 httpd is not designed for multiple concurrent requests. I was surprised by how much difficulty I had trying to find an embedded C HTTP server that is! I ultimately gave up and now simply start *two* HTTP servers on the ESP32 for this purpose. When a firmware upload is sent to...

Possibly ESP32 errata 3.11:

When certain RTC peripherals are powered on, the inputs of GPIO36 and GPIO39 will be pulled down for approximately 80 ns.

"Certain RTC peripherals" includes ADC1.
