You may encounter a situation where your device crashes and are left with a stacktrace, below are two methods of decoding them.
|
|
|
|
## Manual
|
|
|
|
:::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.
|
|
:::
|
|
|
|
First save the backtrace string to a text file:
|
|
|
|
```text title="backtrace.txt"
|
|
Backtrace: 0x....
|
|
```
|
|
|
|
Now run the exception decoder:
|
|
|
|
```shell
|
|
bin/exception_decoder.py backtrace.txt
|
|
```
|
|
|
|
## Real Time
|
|
|
|
In order to decode stack traces in real time, kep the following command (replacing `DEVICE_PORT` with your device's port) running in your terminal with the suspect device connected
|
|
|
|
```shell
|
|
pio device monitor --port DEVICE_PORT -f esp32_exception_decoder
|
|
```
