Reading negative temperature and N/A temp

What version of the firmware does M115 report? Might be useful in troubleshooting.

That's why you're not getting a reading, you need have to define the pin that it's using.

Yep, use that. In fact, looks like you're either modifying or creating a new config file based off of a RRF2x one. You might want to run through the web configurator and generate one for RRF3

I used and got a different error!

Most likely your tool settings. Update these secttions.
