Gecco FTDI

Windows

D2XX Driver should be pre-installed.

Linux

Install D2XX driver: Installation Guide

Check if VCP driver gets loaded:

sudo lsmod | grep -a "ftdi_sio"

If yes, create a rule e.g., 99-ftdi-nexys.rules in /etc/udev/rules.d/ with the following content to unbid the VCP driver and make the device accessible for non-root users:

ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6010",\
PROGRAM="/bin/sh -c '\
    echo -n $id:1.0 > /sys/bus/usb/drivers/ftdi_sio/unbind;\
    echo -n $id:1.1 > /sys/bus/usb/drivers/ftdi_sio/unbind\
'"

ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6010",\
MODE="0666"

Reload rules with:

sudo udevadm trigger

Create links to shared lib:

sudo ldconfig

Mac

See FTDI Mac OS X Installation Guide D2XX Driver section from page 10.

UART (Gecco/CMOD)

In case a Board UART is used, there should be no specific setup to perform, the FTDI USB-UART Converters present on the Nexys Video and CMOD boards are recognised by all the operating systems natively.

On Linux, Serial ports are usually restricted to members of a specific group, which would be dialout for ubuntu. Just add your user to this group:

sudo gpasswd -a $USER dialout

Now re-open a new terminal, or login/logout to have the change take effect, you can check by using the id command, for example:

id 
uid=1001(xxx) gid=1002(xxx) groups=1002(xxxx),4(adm),20(dialout),27(sudo),46(plugdev),117(netdev),137(libvirt),1001(docker)
