While I was working with the IR-Lock MarkOne beacon I noticed that after the start-up of the board or after restarting it (grounding LED shutdown * testpoint), in 80% of the cases a group of 6 LED diods (L13-L18) blink until shutdown, and in 20% of the cases they just shine constantly again until shutdown. Is that normal or is this some sort of bug during the initialization of the MCU? The same things happens to both beacons I have.
