    When I run

    > sudo i2cdetect -y 1

    I see a device driver loaded at 0x6f. I would like to add a device that uses that address. Can I remove the current device? How?

    Thanks

    If there is a device at 0x6f then it should be declared in the dts files if a device driver is using it. If the device isn't in the dts files then the i2cdetect is finding a device on that address but no kernel device driver is loaded.

    I do not have a brick sensor connected. The 0x6F went away, so I must have made a mistake in my code running on the M4. I am curious though, why can I run i2cdetect on the A9 and see devices that are supposed to be connected to the M4?

    I don't know, only that I2C-2 is also the Arduino I2C bus.
