Hi Jon,
thanks for the quick answer.
I attached a picture of the device manager output. Except the german translation all as in your picture.
Yes, the device seems to disconnect with the dingle ling sound when connected via Vivado.
If connected without acces by vivado it stays connected.
I haven't tried the microblaze tutorial yet. I tried this one: Programming Guide
Can the board be bricked?
regards,
lawi
