Can't update on MacOS (MBP 16")



  • Hi,

    New to pycom and playing with my first kit - expansion board 3.1 + lopy module. I am trying to follow the instructions and updating the expansion board but I am not getting anywhere.

    Running the command: dfu-util -D /Users/nogi/Downloads/expansion31_0.0.11.dfu, I get

    dfu-util 0.9

    Match product ID from file: ef99
    dfu-util: More than one DFU capable USB device found! Try `--list' and specify the serial number or disconnect all but one device
    
    

    Running with --list I get:

    Found DFU: [1edb:be2d] ver=0102, devnum=4, cfg=2, intf=0, path="0-2", alt=0, name="UNKNOWN", serial="206D316D5856"
    Found DFU: [1edb:be2d] ver=0102, devnum=4, cfg=2, intf=0, path="0-2", alt=0, name="UNKNOWN", serial="206D316D5856"
    Found Runtime: [04d8:ef99] ver=0007, devnum=8, cfg=1, intf=0, path="0-2", alt=0, name="UNKNOWN", serial="UNKNOWN"
    

    There is only the one device that matches yet it doesn't find it. The serial number for the expansion board shows as UNKNOWN so can't specify serial #. Even if I just say UNKNOWN it still doesn't work:

    dfu-util -D /Users/nogi/Downloads/expansion31_0.0.11.dfu -S UNKNOWN
    dfu-util 0.9

    Any suggestions?

    Hi,
    At the moment we have an issue with the dfu-util program on MacOS. On the other operating systems, the tool works fine. Sorry for the inconvenience.

    Best,
    Gijs



  • I have the same issue, does anyone know how I can get a firmware update to work on a Mac?
