The TRM does include a Glossary that defines RTC: Real Time Controller. A group of circuits in SoC that keeps working in any chip mode and at any time. And clarifies how RTC Slow and Fast memory got their names in 1.3.5.3: The ROM as well as the SRAM are both clocked from CPU_CLK and can be accessed...

I looked into this recently, too, on ESP32. First I tried to use the slow clock frequency adjustment register (RTC_CNTL_SCK_DCAP) to periodically tune the frequency in deep sleep wakeup stubs. After too long, I noticed that increasing the frequency is detrimental to sleep power consumption, so that ...

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.
