HI @priyanshu_pranay

You need to run `python3 -c "from pynq import Overlay; Overlay(‘hall.bit’) as root with the proper environment variables sourced as described in this post:

Run python scripts in Pynq Environment

Hi @DiogoBaptista There are three steps to running PYNQ code from the command line: Make sure you are in sudo privileges (e.g. sudo su) Source the pynq venv environment source /etc/profile.d/pynq_venv.sh Source the xrt environment source /etc/profile.d/xrt_setup.sh You should now be in the right environment to run PYNQ code. You could put both source commands into a shell script which you can run whenever you want. Thanks, Josh
