Building the PlutoSDR Firmware Image

This is done on a Ubuntu 17.10

Attention: At the moment the build fails under Ubuntu 17.10, because of the flex package.

Xilinx Toolchain

Download the latest version (2017.2 at the moment!) of Vivado which will be used for writing/editing/modelising/whatever all the files. You need to download a Full Installer, whenever it's a Web installer or not (depends of the amount of free space you have). You can download it there.


Download a WebPack License on the Licensing Site (From "node-locked" part).

Installing Vivado

Prepare the install directory

$ sudo mkdir /opt/Xilinx
$ sudo chown <user-name> /opt/Xilinx
$ chmod u+rwX /opt/Xilinx

Go to the folder where you downloaded the installer

$ chmod +x ./Xilinx_Vivado_SDK_2017.2_0616_1_Lin64.bin
$ ./Xilinx_Vivado_SDK_2017.2_0616_1_Lin64.bin

Follow the installation wizard and don’t forget to select “Software Development Kit” on the installation customization page. (Vivado System Edition + SDK)

If you have to choose which boards you want to install, you can choose to install everything, it's the best way for not forgetting anything... Or choose to install all the tools and only the Zynq 7 board.
If not, it's just perfect isn't it?

Import your license

Launching Vivado

Source the architecture shell file:

$ source /opt/Xilinx/Vivado/2017.2/settings64.sh

Then launch it:
