Hello,
Last addition to tests list ; I measured the voltage Vcc at the MPU9255 and found 1.7V (looking at the schematics, 3.3V should be expected ; the MPU9250 I had is expecting 3.3V). Close inspection showed an open jumper J10 with one side connected to pin1 (3.3V) of the 40pin connector of the rapsberrypi while the other is connecter to MPU9255 Vcc.
I am wondering if J10 should be closed to supply 3.3V to the MPU9255.
Sean, could you comment on this ?
Best regards,
Xavier.
