CORE2-ROS Boot issue

Hi,

I’ve followed the steps up to this point of step 4:

doing this step with -c rpi instead of -c tinker.

It returns the following error message:

Traceback (most recent call last):
File “/usr/local/bin/stm32loader”, line 9, in

I’ve spent some time looking for a solution, but so far have not been able to find anything.
