[Ritesh]

hi urbanze,
I have gone through this forum,I want to store crash code into esp32 flash.i am using arduino ide..esp idf master.Can you help me to write core dump to flash?How are the steps and how to config in sdkconfig at windows level.Can you share piece of code for writing core dump to flash?

Thanks you.

Hello Simran,

Have you tried ways which have been explained into last post? Because it has been mentioned into sdkconfig to configure coredump for storage and debugging purpose.

The coredump is written to a partition; you could read out that partition on the ESP32 and e.g. send its contents off to a server.

Hello,

Thanks for sharing it which will be helpful for others in case if required for crash dump to store into flash memory and to send over remote location.

hello urbanze, thanks for sharing.
Could you elaborate more on how to do what you mention in point 4?
After I converte the hex data to b64 how should I save the file and what exactly is PROJECT .ELF PATH?

4. After all print occur, I drag this in hex -> b64 converter, save in file and use: espcoredump.py info_corefile -c COREDUMP PATH -t b64 -rom-elf PROJECT .ELF PATH

Thanks
