Motion chip timeout

Getting this intermittenly on a KR proffieboard

Tried os 6.6 and 6.5 – but sometimes it works … sometime it’s giving us no swing/clash sounds (just ignition/retraction/blast)

Is this a dead board?

Make sure there’s nothing shorting SDA or SCL pads.

NoSloppy is right, inspect and measure to make sure that there is nothing shorting or touching the SDA/SCL pads. If that’s not it, then it is most likely a problem with the board itself.
