EspSaveCrash for esp32 ?

[NickChungVietNam]

First of all, many thanks to krzychb created this library. So does EspSaveCrash support for esp32 ? If not, how can i do ?

Hi @NickChungVietNam,

I am happy you like this library!

As for now arduino-esp32 is not yet ready to implement similar functionality. I see two options how do it:

1. Add a user-defined hook to the ESP-IDF panic handler and then use it from EspSaveCrash library as is done for ESP8266.

2. Leverage existing functionality of "Save core dump to flash" by enabling it in arduino-esp32 and prepare convenience functions to:

   • provide the number of core dump snapshots already saved in flash
   • erase the contents of the core dump in flash
   • printout the contents of the core dump in flash

   See also https://github.com/espressif/arduino-esp32/issues/229

In both cases the first step is to update existing esp-idf or arduino-esp32 repository.

Same here. I got spoiled with the EspSaveCrash. The good news is that the ESP-IDF natively supports core dumps. However the option is disabled in arduino-esp32. To enable the option, you would have to rebuild the libraries similar to issue #1142, except that you would enable the core dump of course.

Hi, I have worked on a solution with Arduino framework v1.0.6 and PlatformIO. Here is my Github repo where I explain everything in the README file.

Thx b I'll take a look

Hi @krzychb Thank you for your work!

As for now arduino-esp32 is not yet ready to implement similar functionality.

Look at the changes in this PR: https://github.com/espressif/arduino-esp32/pull/8711/files

Using set_arduino_panic_handler we can set a handler for saving the dump. Do you think it is now possible to add support for esp32 to the library?
