Build process

Get the environment ready

We follow the steps outlined under PYNQ SD card:

• Install a virtual machine running Ubuntu 18_04_4 LTS with more than 150 GB of storage space. Do not update Ubuntu since this will roll the version and make it officially incompatible with the Xilinx tools below (for this build we used Ubuntu 18.04.6 LTS with security updates).

• Clone the PYNQ repository (for this build we used v3.0.1):

git clone https://github.com/Xilinx/PYNQ

• Install dependencies using the following script.

source <PYNQ repository>/sdbuild/scripts/setup_host.sh

• Install the Xilinx tools (for this build we used v2022.1):

  • Vitis (which includes Vivado)
  • Petalinux
  • Go for lunch! This will take a few hours...

• Download the prebuilt board-agnostic (PYNQ rootfs arm v3.0.1) image from Pynq Development Boards and unzip it.

• Download the PYNQ distribution tarball (pynq-3.0.1.tar.gz) from the PYNQ release repository. You will find the distribution tarball under a drop-down called Assets.

• Place both files into /sdbuild/prebuilt/

• Rename files to pynq_rootfs.arm.tar.gz and pynq_sdist.tar.gz

Prepare build

• Clone this repository:

git clone https://github.com/Unprex/Pynq-Redpitaya-250

• Make sure the scripts in the Pynq/boards folder are executable:

sudo chmod -R 777 Pynq-Redpitaya-250/Pynq/boards

Build PYNQ

• Open a terminal and run the settings files for Vitis and Petalinux:

source <path-to-vitis>/2022.1/settings64.sh
source <path-to-petalinux>/2022.1/settings.sh

• Navigate to

cd <PYNQ repository>/sdbuild

• Run the makefile (your password will be required a couple of times)

make BOARDS=Pynq-Redpitaya-250-12 BOARDDIR=/path/to/Pynq/boards

• The generated PYNQ image will be located within <PYNQ repository>/sdbuild/output/Pynq-Redpitaya-250-12-3.0.1.img

• image.its and zImage will be located in <PYNQ repository>/sdbuild/build/RP25012/
