    Has anyone managed to get this to work on a Banana BPI M2 Zero?

    When I connect the module the I2C bus stops responding and reports that it’s locked :-/ Any ideas?

    i2c i2c-0: mv64xxx_i2c_fsm: Ctlr Error — state: 0x2, status: 0x0,


    I was able to locate the related portion of the driver code, but have found no solution as of yet.

    line 320:

    “mv64xxx_i2c_fsm: Ctlr Error — state: 0x%x, ”
    “status: 0x%x, addr: 0x%x, flags: 0x%x\n”,
    drv_data->state, status, drv_data->msg->addr,
    drv_data->action = MV64XXX_I2C_ACTION_SEND_STOP;
    drv_data->rc = -EIO;


    So I did a full header trace with a DVM and discovered that one of the 3.3v pin-sockets on the header was misshaped, I replaced the header with an extra I had on the bench and I am in business! I will report back once I actually use the module in practice to confirm general compatibility.
