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.

Please provide more details about the FPGA architecture and the pynq python setup that you are using. Also the PS-PL registers that you are using.

Yes, this is the issue. The latest version of PYNQ is v2.6 and you should use Vivado 2020.1.
