Receive and understand Errors message from Odrive

Currently I am leading tests on Odrive and I meet some issues during the initialization phase of the motor.
After reading previous posts I think it is possible to receive errors message from the card
but I don’t understand how to do.

The card sends message by the USB port ? It isn’t very clear

Sorry about the confusion. The documentation is fairly inadequate, and I apologise for that. The main reason for this is because the interface needs some improvements and should change soon.

The richest way to debug the ODrive is with the debugger, launched via the console or Eclipse.

Also supported is to read/write configuration, commands and errors from the ODrive over the USB. I just wrote some documentation for this, please see it on the ODriveFirmware readme.
