Making Drivers Work with Old LoPy Hardware

(Brady Aiello) #1

I got a LoPy (version 1.0r) in October 2017, and the expansion board version 2.1A. I’m trying to install the driver now. I’m on Windows 7 and following the instructions
here. I’m going through the steps, but my device still does not show up in the Windows Device Manager. I’m wondering if the instructions for installing the drivers updating firmware are still valid given the older hardware, and if not, what I can do to get the board showing up as a device. The instructions on that link are here:

To uploaded the latest DFU firmware to the Pytrack/Pysense, first install the DFU drivers to the host computer. Open Zadig and select libusbK as the driver.
To install the drivers, the Pytrack/Pysense board must be in DFU-mode:

  1. Disconnect the USB cable
  2. Hold down the button on the shield
  3. Connect the USB cable
  4. Keep the button pressed for at least one second
  5. Release the button. When the board is connected in DFU-mode, it will be in this state for 7 seconds.
  6. Click the“Install Driver button immediately. If the driver was unsuccessful, repeat from step 1.


I’ve done this without any problem lot of time with same devices as you. I do not remember having installed any driver except Zadig and dfu tools, but I’m on Windows 10 x64
I suggest to ask in pycom forum, chances to have a better answer will be higher :smiley:
