Coredump info is incomplete

Postby xzwang » Thu Feb 09, 2017 1:22 am

I have enabled the config of coredump and print it on UART. However the Coredump info is incomplete, and it can't be analysed by espcoredump.py. I got the coredump info with the "CORE DUMP START", but there is no "CORE DUMP END". The followed info is what I have gotten.

Code: Select all

Does anyone know why the coredump info is incomplete?
Thanks.

It looks like for some reason, dumping the core took long enough for a watchdog to trigger. We merged a fix for that bug three days ago; can you try pulling esp-idf and then see if the problem is still there?

Coredump info is complete after IDF updated.
Thanks.

But I am wonder how to analysis the core info like this:

===================== ESP32 CORE DUMP END =====================
===============================================================
Done!
The crash happened situation:
1,ESP32 connect to AP as STA.
2,after several hours, Uart print SYSTEM_EVENT_STA_DISCONNECTED repeatedly.
3,ESP32 crashed.

How to confirm which task make the crash? It looks like not my app caused this crash.
Can you give me some suggestion? Thanks.

Might this help? It is a tutorial on using the core dump functions to determine where within code a panic occurred.
