Stacktraces

Decoding Stacktraces

You may encounter a situation where your device crashes and are left with a stacktrace, below are two methods of decoding them.

Manually

info

This method uses the symbols of the firmware.elf file generated from your latest build, you may wish to rebuild to get up-to-date symbols.

1. Save the backtrace string to a text file:

   backtrace.txt

   Backtrace: 0x....

2. Run the exception decoder:

   bin/exception_decoder.py backtrace.txt

In Real-Time

In order to decode stack traces in real time, keep the following command (replacing DEVICE_PORT with your device's port) running in your terminal with the target device connected:

pio device monitor --port DEVICE_PORT -f esp32_exception_decoder
