Debugging ESP32 resets
Posted: Wed Jan 17, 2018 10:13 am
Hi,
I ran into a problem with my ESP32 project. I use the ESP32 to control a piece of external hardware (an inverter), which works really well. Unfortunately, the chip resets itself after a few hours. This is the only thing I see in the logs after the reset:
Apparently, the watchdog caused the chip reset. But that's it, it doesn't give me any more info. How can I debug which task / function failed to feed the watchdog? The log mentions with the location of the CPUs' program counter registers. Is there any way to find out which section of my code this register was pointing to at the time of the reset?
Thank you very much for any suggestions!
