Hi,
I don't see this problem from my side.
first please check device manager if USB tap is well recognized. This is the screenshot from my side.
do you use evb/demo board or customized board? If you use demo board, please make sure the jumper setting is correct.
if you use customized board, please create a new stationery project for your board by doing New -> DSP56800x EABI Stationery -> Your Board(56F803) -> Simple C and Assembly. Then change the Connection Settings to USB Tap and set the JTAG Clock Speed into 500.
I also suggest you test your usb tap and cable with another computer, I ever had customer got similar error as yours because his usb tap was broken.
Have a great day,
Jennie Zhang
