Otherwise only the super user can make use of microcom. To use immediately you can use: sudo gpasswd dialoutįollowed by (your old shell settings will be forgotten): newgrp dialout microcom -p /dev/ttyUSB0 -s 115200Īfter installing microcom you will probably want to add your username to the dialout group: sudo usermod -a -G dialout $USER Microcom, CuteCom or Screen can be used to connect to this console. The USB-UART bridge is normally shown in Ubuntu as /dev/ttyUSB0 ~ /dev/ttyUSB3.
The FTDI USB-UART bridge chip used on NEXYS4-DDR is supported in Ubuntu 18.04 and does not require extra driver installation.
We recommend to use the driver packages provided byįor 64-bit Ubuntu, please download and install the following two deb packages: The default JTAG and configuration method for both the Genesys2 and the Note to export the XILINX_VIVADO variable which is required by FPGA simulation. # exporting XILINX_VIVADO is required for FPGA simulationĮxport XILINXD_LICENSE_FILE=/PATH/TO/LICENSE/FILE Source /local/tool/Xilinx/Vivado/2018.2/settings64.sh # source the prepared script, assume Xilinx is installed to Here is an example script for setting up the Xilinx Vivado suite. Signal integrity on the SD-Card interface is a limiting factor on performance, the PMOD interface However it requires a separate PMOD if you want to use the SD-Card support. It would be relatively easy to support the ArtyA7-100 which is cheaper and has a larger DDR3 ram than Moreover its peripherals are largelyĬomplementary to the Nexys4-DDR, rather than being leading edge propietary parts. Genesys2 is also supportedīecause it is the default platform for Ariane. Nexys4-DDR is supported because it is low cost and widely available.

Such a license will allow a user to implementĭesigns targeting the specific FPGA used in the development kit, such as Voucher will allow the user to generate a site and device locked license For users who bought anįPGA development kit, such as the Genesys2 kit, a voucher may be enclosed. LicenseĪ license is required to use the Xilinx Vivado suite. The pre-build binary images were created with Ubuntu 18.04 LTS. If your machine cannot meet these requirements then synthesis should be able to run, albeit rather slowly, inside a virtual machine. If you must add the Xilinx tools to the path (for example to facilitate interactive use) make sure the version of cmake on the path is not too old when running buildroot. Do not attempt to use a version of Vivado earlier than 2018.2. If your administater mandated a different path, update the XILINX_ROOT and if necessary XILINX_VER in fpga/Makefile. By default the Xilinx installer installs to /opt/Xilinx (which will typically be a symbolic link to a shared disk). To avoid contaminating the LD_LIBRARY_PATH this flow explicitly sets the path to Vivado in fpga/Makefile. This will prevent more modern tools such as cmake from running properly. Xilinx installation trees contain their own incompatible version of certain system libraries to “improve portability”. To make a symbolic link to a larger disk (which could be a server), for example: cd /optįor this version of Vivado the Xilinx recommended O/S 64-bit Ubuntu 16.04.3 LTS / 18.04 LTS. Typically /opt will be on the relatively small root partition of the computer, so it is necessary The default location is /opt/Xilinx and this will be the location referred to in the tutorial. The installation requires up to 30 GB of disk space.

Moreover the code needs modernisation to work with Vivado 2019.x, because Xilinx thinks ‘input’ is not equivalent to ‘input wire’. The version used in some previous releases 2015.4 is known NOT to work on this release. For this release, we recommend Vivado 2018.x.
