Hi Mike,
It the part has already programmed, when the board connect to the GUI, Enable Target, the “Buck Supplies” and “Linear Supplies” panel will show the fuses information about the part, you can check if this is what you want.
To do the program, after load the script, it needs to click the “Convert Script File” button on the bottom firstly, then you will the the “PROGRAM” button will switch from gray to green. It is recommended to click “Verify After Programming” button at the same time.
