## Building in debug mode
You can also build firmware in debug mode to see log output or run tests. To avoid building firmware in debug mode accidentally, we do not provide a _make_ target. You need to rewrite `PYOPT` variable to `0` in `SConscript.firmware` file and then build the same way. The change is intentionally not _gitignored_.
You can also build firmware in debug mode to see log output or run tests.
```sh
sed -i "s/^PYOPT = '1'$/PYOPT = '0'/" SConscript.firmware
pipenv run make build_firmware
PYOPT=0 pipenv run make build_firmware
```
You can then use `screen` to enter the device's console. Do not forget to add your user to the `dialout` group or use `sudo`. Note that both the group and the tty name can differ, use `ls -l` to find out proper names on your machine.
