Wifi Power Manager Stack Overflow

[lil_spli]

Hi

I'm getting the following stack overflow occasionally when using Wifi on my app.

Code: Select all

***ERROR*** A stack overflow in task pmT has been detected.
abort() was called at PC 0x4008f0d4 on core 0
0x4008f0d4: vApplicationStackOverflowHook at /Users/simon/esp/esp-idf/components/esp32/./panic.c:648

I don't see a way to configure stack size for that task. Any way I can find out why this is happening and how to stop it?

Thanks

Hmm, with that backtrace, it actually smells like some other task overflowed the stack instead; FreeRTOS is trying to switch either to it or from it to the power manager task and crashes halfway the processs. You might want to see if allocating more stack to the task created just before or after WiFi startup solves the issue.
