Link to USB Driver for XR21B1411 (Not needed for F256K2)
XR21B1411 USB Driver for PC/Linux. The MAC is outdated. (Note: Driver is not needed for the F256K2) [1]
On the F256K2 the XR21B1411 has been replaced by a FT4232, to allow direct use as a JTAG controller for the FPGA.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 Rasberry 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.
To perform a full Kernel & SuperVASIC 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).
