Speedval Graphical User Interface (GUI) can not connect to the Control Cards

demosupen

Hi

I have tried to use the Speedval Graphical User Interface (GUI) to connect the TI Control Cards TMDSCNCD280039C for the motherboard MOD-MB-HB-0900V-40A. The Firmware for Wolfspeed's SpeedVal Kit is flashed to the Control Card, and can be identified correctly by the computer. But when I use the Speedval GUI to connect the TI Control Cards, it fails to connect after I choose the right COM port. Can anybody help me to deal with this? Thanks in advance.
