Hi,
- What's your IDE? Do you use KDS? This is how KDS debug setting with P&E OpenSDA interface from my side

- Besides, I suggest you check the basic connection: create a NEW project under a NEW workspace. See how it works.
- To verify it the problem is related with firmware, test the board connection with another computer.
Have a great day,
Jennie Zhang
