RTC watchdog is COMPLETELY undocumented. Seeing how it is the only mechanism to do an main system reset, the is very important to me. I saw a reference to some registers used

[ESP_Sprite]

The RTC documentation in general is still a work-in-progress... if it's any help, the RTC watchdog, apart from the reset stages (which iirc do a SoC reset instead of a CPU reset), is exactly the same as the timer group watchdogs. Also, if you want to reset the chip, does the ROM function software_reset() not do what you want?

[bkgoodman]

I *really* need to the RTC watchdog - because I need my circuit to be able to perform a full-system-reset in the event of something bad happening. (It is being designed for installation in a 7/24 lights-out [remote] environment. I have already seen cases where some of the libraries - like Secure WiFi can crash on some edge cases. I need the chip to hard-reset itself out of such scenarios).

I would also appreciate a thorough documentation of TASK- and RTC-Watchdog. Our use case is the same as bkgoodman. Some of our products are used in really remote areas were user reset is not an option or would cause a technician to drive several hundreds of kilometers to do a manual reset.
Since we also have seen lockups after crashes (even with the option to "reboot on exception" set in sdkconfig) this pretty much ruins these product.
Of course we could still add a "hardware watchdog" by means of circuitry but that would add a really unpleasant layer of complexity to our products.

So I would request the WDT docs and also an example/best practice/guide or whatever on how to prevent lockups in software.

Yep - Exactly what Novalight said

Hi

there was a Wrover Guide Request in the past from me
now found and spottet in the wild :

Hello,

Just saw this thread. I'd like to request the pinout for the Geekcreit/DOIT esp32 VROOM-32 devkit V1, a "clean" version. doit.am posts no data for their product. The supplied pdf schematic makes it too difficult for quick pin reference when coding.

Thank you for the help,

Alex

I am looking for the certification guide (ESP32_Certification_and_Test_Guide__EN.pdf). I have seen it referenced in the forums but can't find it anywhere.

It is easy to find on espressif.com, http://www.espressif.com/en/support/dow ... ther-tools

If I want to port the esptool.py to another language, is there a document somewhere specifying the protocol used to communicate with the ROM bootloader? Or do I have to infer it from the python source? I will do the latter if the former isn't available, but having documentation would speed up the process.
