Hi, I had Nexsys 3 for evaulation a while back; however, I used Xilinx USB-II cable to program FPGA and its SPI Flash. Today, I tried to copy a bit file to USB stick drive (thumb drive), and it cannot configure FPGA. I had both jumpers removed for J8 (Config Mode Select). I have tried USB from 1GB to 512MB with combination formats as NTFS, FAT, FAT32, exFAT, and Nexys 3 failed to configure from USB HID (HOST J4). The orange LED4 (BUSY) flashing forever. I tried a simple code (~312KB bit file) to turn on 8 green LEDs with 8 Slide Switches. The SPI and BPI Flashes can load FPGA Config, except the USB. I made some research and found Digilent suggest to update USB HID Firmware. However, it wasn't made public. Could anyone please help or share the FW with instruction?

To whom it may concern, I have the Nexys4 DDR board (Artix-7). The follow the schematic Rev-C1 to verify features/functions with the board Reference Manual. However, I cannot find J6 (UART) and/or FTDI chip on schematic. Is it possible for me to obtain a full schematic design? Thank you.
