Ultra96v-2 Boot Error

[dere_mustapha]

Hello,

I am trying to run my script to startup without having access to the Jupyter notebook. The script worked perfectly when Jupyter notebook was used but throws errors when expected to run on boot.

I followed instructions from Starting PYNQ Programs At Boot. I am using Ultra96-v2, Vitis1.4, Pynq 2.7.

Thanks.

Looking through systemd services I make my way to pl_server.sh and see that there are ind…
