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:

text title="backtrace.txt" Backtrace: 0x....

  1. Run the exception decoder: shell 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
