Hi, I'm running the example code to interface to the IMU sucessfully on my OAK-D PoE, and am evaluatings an OAK-FFC-4P-PoE as well, but the the same basic IMU code returns the following error:
[18443010D18CBD0F00] [134.89.11.133] [5.412] [IMU(0)] [critical] IMU driver failed with error code 1. Your board likely doesn't have IMU!
The schematics and datasheet pages say the unit is installed.
