RFSoC 2x2 kit University , Xilinx ZYNQ UltraScale+ RFSoC ZU28DR FPGA model no. HTG-ZRF2-XUP
board boot image = (CASPER) rfsoc2x2_casper.img
Ubuntu 20.04 LTS , Kernel 5.15.0-71-generic
I am connecting the Micro USB 3.0 from the 2x2 board to a PC. I have installed the cable drivers of Vivado. I have installed kernel drivers for cp210x, usbserial, and ftdi.
dmesg | grep tty shows nothing new. dmesg | grep USB shows nothing new. lsusb does not show a connection to this board.
There is no physical problem with the cables as this board connects and communicates fine with the PYNQ framework.
(Additionally I have even tried to create a serial connection to this board with a separate PC running Windows 10. Silicon Labs VCP drivers did not work. Silicon Labs Universal drivers did not work. Silicon Labs Dual CP2105 USB to UART bridge Standard COM Port did not cause the computer to recognize this board.)
What am I doing wrong here? Should I purchase a Xilinx Platform Cable II? Or other?
