Hi,

Just remember that the programmer need to list the same number of devices in the JTAG on the physical board. So, if there are 3 devices in the JTAG chain on the board, then you need to add the same 3 devices in same arrangement in the programmer. The easiest way is to perform auto detect then the program can detect the number of physical devices on the board. However it is good to know the actual device part number as the programmer may detect multiple devices which has the same idcode.
