How to solve the above UBL error.
I suspect that it is expecting to receive a valid chip type ID at this stage

and not getting it, similar to this error in the TMCL IDE

mentioned here in the EngineerZone
Are you sure that your interface is connected to the COM3 virtual com port in device manager and that it is showing as being ok ?

yes. Please check the device manager I have uploaded. It is showing com3 for TRINAMIC.
I notice in the PyTrinamic example they are using UBL Tools v 1.0.1

Perhaps another option is to try bypassing the Landungsbruecke interface board with a USB-UART adapter cable

as you wouldn't need to use the Python wrapper to launch UBL Tools

This looks a useful resource
https://github.com/analogdevicesinc/PyTrinamic/commit/e9e972d3ef134aa44c0190ad7edfff06181efde8
as it describes how to use the TMC9660-3PH-EVKIT to spin a BLDC motor with feedback using PyTrinamic, but you still need the UBL Tool to upload the config file.
