Hi, The Quartus Prime programmer Pro doesn't find the device on board 1SM21BHU2F53E2VGS1 but lists devices 1SM21BHU2S... there is no F devices on the list. Using Quartus Prime Pro 19.1 or 18.1 How can I select the right device. Thanks, Des

Strange. So I presume your Quartus project is set to the correct device. When you open the .sof file in the Programmer, does the correct part number appear? You don't need to use the auto detect (you can select any part in that list) if the targeted part shows up correctly in the Programmer extracted from the .sof.
