PYNQ Sobel Project

This repository hosts the PYNQ Sobel project compatible with PYNQ image v2.7 for the PYNQ-Z2 and PYNQ-Z1 development board.

Quick Start

Follow the instructions below to install the System Generator projects on your PYNQ board. You will need to give your board access to the internet.

• Power on your PYNQ development board with an SD Card containing a fresh PYNQ v2.7 image.
• Navigate to Jupyter Labs by opening a browser (preferably Chrome) and connect to http://<board_ip_address>:9090/lab.
• We need to open a terminal in Jupyter Lab. Firstly, open a launcher window as shown in the figure below:

• Now open a terminal in Jupyter as illustrated below:

Run the code below in the jupyter terminal to install the System Generator projects.

pip3 install git+https://github.com/strath-sdr/pynq_sobel

Now, install the notebooks by running the following command.

python3 -m pynq_sobel install

Once installation has complete you will find notebooks in the Jupyter workspace directory. The folder will be named 'pynq_sobel'.

You can also clean the notebooks by running the clean command, and uninstall the notebooks by running the uninstall command.

Using the Project Files

The following software is required to use the project files in this repository.

• Vivado Design Suite 2020.2
• System Generator for DSP
• MATLAB R2020a

System Generator

Ensure System Generator has been configured correctly. Now, load System Generator and open a project from the location below:

/<repository-location>/boards/ip/sysgen/

You can simulate and generate the project as required.

Vivado

This project can be built with Vivado from the command line. Open Vivado 2020.2 and execute the following into the tcl console:

cd /<repository-location>/boards/<board-name>/pynq_sobel/

Replace the board and project name with the preferred values. Now that we have moved into the correct directory, build the Vivado project by running the make commands below sequentially.

make block_design
make bitstream

Alternatively, you can run the entire project build by executing the following into the tcl console, which will clean the repository after the bitstream has generated:

make all

After build, a bitstream folder will be made available in the project folder.
