Intermittent checksum error

Hi,

We are using the TMCM6214 and communicating with it using the PyTrinamic Python library.

We are observing intermittent checksum errors during communication. (Full error below) It generally occurs when we poll the motor driver if we have reached the final position, which we do in a 500ms loop.

Basically we have two questions regarding this:

1. Is this expected? I.e., are checksum errors common, or does it indicate a hardware issue?
2. If the latter, what steps can we take to troubleshoot the issue? Its connected via USB.

Full error:
