• All Pynq-Z1 images including the latest are available here:

file://xsj-pvstd2t01-w/xrlabs/grahams/public/pynq-z1_images/

• After imaging, change the board's hostname to avoid network conflicts

sudo /home/xilinx/scripts/hostname.sh A_UNIQUE_HOSTNAME

This is a recommended way to update the pynq package. The script will do the following:

• Back up the existing package on board.
• Git clone from the repository.
• Install the pynq package.
• Copy board-specific files into the pynq package.
• Copy the latest Jupyter notebooks into /home/xilinx/jupyter_notebooks.

For the first step, the folders getting backed up include:

• docs: the documentation files saved in /home/xilinx/docs.
• jupyter_notebooks: the original Jupyter notebooks saved in /home/xilinx/jupyter_notebooks.
• root: the scripts used during the boot sequence.
• scripts: the scripts saved in /home/xilinx/scripts.

To run this script, first verify the $BOARD environment variable has been set correctly:

echo $BOARD

• If $BOARD is not set, add export BOARD=Pynq-Z1 to /home/xilinx/.profile. Then either reboot the board, or run the following:

   source /home/xilinx/.profile
  

• If $BOARD has already been set, just run:

   cd /home/xilinx/scripts
   sudo update_pynq.sh
  

It is not recommended to update pynq using pip, since there are still many board-specific files to be copied from the repository.

The developer mode will pull entire github repository, but again, the board-specific files are not copied to pynq.

# (deprecated)
sudo -H pip install --upgrade 'git+https://github.com/Xilinx/PYNQ@master#egg=pynq&subdirectory=python'

# (deprecated) Developer mode
sudo -H pip install -e 'git+https://github.com/Xilinx/PYNQ@master#egg=pynq&subdirectory=python'

The pytests have to be run under root privilege:

cd /usr/local/lib/python3.4/dist-packages/pynq
sudo py.test -vsrw
