I downloaded the software pack from Github STM32CubeH7/Projects/STM32H745I-DISCO/

, and followed the instructions in UM2222 manual.

I can connect st link com port. But no data is shown on the oscilloscope window.

Hello @DZhan.9​ ,

Did you follow the instruction in the readme file ?

Make sure to Apply an external signal to the board input (PA0, CN7 Connector pin A2).

Yes. I connected it to the DAC output. I verified the DAC output using my own scope. It works as expected.

I also tried Wireshark to check USB communication. I cant see packets between the microcontroller and my laptop.
