I need the help please
I worked on the bord Pynq_Z1

Hi, please be more specific for the question. Which version of pynq is this? Did you use tcl or hwh as the companion file to the bitstream?

thank you for interacting with me, the problem lies in the version of the pynq image, I used version 2.0 and the work I did by vivado 2018.2 there are not compatible.
