    Hi, I'm using a brand new VOXL 2 flashed with 1.7.1 and I'm having issues using I2C on port number 5. I've been able to use it without problems in the past, but all of a sudden I'm not seeing any devices on it when running i2cdetect -r -y 5 and I'm getting the following error messages in the kernel log; this is happening with any I2C device on the port:

    [   14.043169] i2c_geni 990000.i2c: Bus arbitration lost, clock line undriveable
    [   14.043364] i2c_geni 990000.i2c: Bus proto err, noisy/unepxected start/stop
    [   14.043492] i2c_geni 990000.i2c: i2c error :-71

      @czarsimon , can you please clarify where you have your device plugged in (based on the connector definitions here : https://docs.modalai.com/voxl2-connectors/)
