Odrive 3.6v 56v can't be read on Mac OS 10

Support
1

I am new to using Odrive and while setting up my controller using the steps provided in the [Getting Started Guide] (https://docs.odriverobotics.com/#downloading-and-installing-tools) I couldn’t find my device, powered by a 36v battery. My first thought was to updated the firmware with odrivetool dfu but it brought up the error below.
Any tips and advice would be greatly appreciated.

Austens-MBP:~ austenfurutani$ odrivetool dfu
ODrive control utility v0.5.1
Waiting for ODrive...
Traceback (most recent call last):
  File "/usr/local/bin/odrivetool", line 143, in <module>
    odrive.dfu.launch_dfu(args, logger, app_shutdown_token)
  File "/usr/local/lib/python3.8/site-packages/odrive/dfu.py", line 450, in launch_dfu
    devices[1] = odrive.find_any("usb", serial_number,
  File "/usr/local/lib/python3.8/site-packages/fibre/discovery.py", line 179, in find_any
    return result[0]
IndexError: list index out of range

Thank you for your time.

Is the green light on the board coming on? If it seems to be on and working but you can’t get it to be seen and can’t get it to flash, even using the information here, https://docs.odriverobotics.com/odrivetool#device-firmware-update then you may want to try an STLinkV2.

The DFU issue you’re seeing is the same bug as described here:

In your case the file that needs to be edited is /usr/local/lib/python3.8/site-packages/fibre/discovery.py.

After flashing the new firmware make sure that the device’s DIP switch is in “RUN” mode (as opposed to “DFU”) and then power-cycle.

I have applied the code to discovery.py and now I have the following error
