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.
Save the backtrace string to a text file:
backtrace.txtBacktrace: 0x....
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
