    i2cdetect doesn't return anything

    Bandan

      Hello,

       

      I am trying to follow the instructions at 90 (References) Flight Controller and Compute Board: Sensors GPIOs LEDs CAN bus · intel-aero/meta-intel-aero Wiki · GitH…  to access the magnetometer sensor but when I run i2cdetect, it doesn't detect anything.

       

      root@intel-aero:~/aero_sensors# i2cdetect -y -r 2

           0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

      20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

      30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

      40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

      50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

      60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

      70: -- -- -- -- -- -- -- --

       

      I hope I am missing something obvious but I am not sure that could be! Any clues ? I looked at the bios and don't think I saw anything i2c related that has been disabled or could be related.

       

      TIA,
