USB Port

F256 Jr. / F256K

You will need to have the XR21B1411 USB Driver for PC/Linux. The MAC is outdated. (Note: Driver is not needed for the F256K2) [1]

F256K2

On the F256K2 the XR21B1411 has been replaced by a FT4232, to allow direct use as a JTAG controller for the FPGA. There are 3 virtual serial ports (channels) enabled. The first connected to the Raspberry PI Nano (on-board) that manages the FPGA loading, the second one is the Debug port, and the third one is the system UART.

Therefore, on a F256K2 you want to select the second COM port that gets added to your system. On my Windows 10 system, the F256K2 USB-C connection added ports COM5, COM6 and COM7. All three coming up just as generic FTDI manufacturer USB ports.

Update batch file to point at correct port

To perform a full Kernel & SuperBASIC update, I simply downloaded the Complete Package (above) and edited the update.bat batch file to instead specify my system's COM6 (i.e. the 2nd added Port).
