unexpected nmea sentence crashing the kbox

[lfrancois]

It seems one of my NMEA 2000 device crashes the kbox. I am going to try to isolate the device to provide you more information.

Any idea how to troubleshoot it? I am running the development branch right now.

Here are the logs from the serial console.

It seems not related to the PGN above. Same issue with a different PGN.

D NMEA2000Service.cpp:37 Received N2K Message with pgn: 127505

As soon as this sentence happens the kbox dies and the select button becomes unresponsive.

After a quick troubleshooting session, it seems two of my NMEA2000 devices are causing the problem:

• Airmar P79
• NAVICO TEMPERATURE SENSOR NMEA 2000

The issue looks to come from the SDCard logging. As soon as I comment it, it works as expected.

@lfrancois did you ever see this again? can we close this now?

Since the new kbox, new firmware, new sd card, everything works fine! :)
