Firmware upgrade expansion board v 3.2 manjaro
-
hi, do we have any linux users who managed to do the firmware upgrade on the expansion-board (which is step one of https://docs.pycom.io/gettingstarted/connection/lopy4/) ?
when I follow the steps specified (https://docs.pycom.io/pytrackpysense/installation/firmware/) I get the error messages: "dfu-util: Cannot open DFU device 04d8:ef99"
and "dfu-util: No DFU capable USB device available". I searched for solutions all day and am none the wiser so I thought maybe someone here encountered this issue and managed to solve it, if so any tips are much appreciated!
what I did:
I installed dfu-util
I added myself to the uucp group (instead of dialout, because as I understand it that does not exist for manjaro but uucp seems to be the one i need to use instead. I came to this conclusion after I did a "stat /dev/ttyACM0").- Disconnect the USB cable
- Hold down the S1 button on the shield
- Connect the USB cable
- Keep the S1 button pressed for at least one second
- Release the button. When the board is connected in DFU-mode, it will be in this state for 7 seconds.
this is the output:
DFU suffix version 100
Match vendor ID from file: 04d8
Match product ID from file: ef99
dfu-util: Cannot open DFU device 04d8:ef99
dfu-util: No DFU capable USB device available -
Never mind, I found the solution. For anyone who faces this same problem: you have to add yourself to the "storage" group to solve this problem :)
