I looked into RTIMULib and best I can tell, from reading old threads, this has to have been implemented properly a long time ago to work with the 9255 so shouldn’t need updating. I installed it anyway, it made no difference. Running “RTIMULibDemo/RTIMULibDemo” generates the same “I2C read error from 12, 16 - Failed to read compass fuse ROM” error. Are we looking at a bad MPU9255 board?
