Hi Pinias!
The LED of a DP6xx straight from production flashes when any of the CAN busses are in BusOff state. During BusOff the LED will blink with 1Hz (on 200ms, off 800ms). As found in the template.
You are able to change these settings in your application and if you do, as soon as you download your own application with your settings of the LED this behaviour will change.
Best regards
