hi! information board : pynq-z2 version : v2.5 I try to use axi gpio to control my design, the block diagram is showed below: ![image](https://us1.discourse-cdn.com/flex019/uploads/pynq1/original/2X/2/286ddf30fb856d232319dcd01fb7686784bfa39c.png) My code is below: ![image](https://us1.discourse-cdn.com/flex019/uploads/pynq1/original/2X/0/0d1c562e7cbb052962894c8f8e3dcdf474ababf1.png) Are there something wrong in my design or code? ---

Hi @leonard, What is the output of `overlay.ip_dict`? Mario ---

HI! Thank for your reply. I’m not sure. I follow the example code from [AxiGPIO — Python productivity for Zynq (Pynq) v1.0](https://pynq.readthedocs.io/en/v2.3/pynq_libraries/axigpio.html) ---

Can you please run that on your jupyter notebook after you create the Overlay object? Report the output please. ---

Hi! I try to use another M\_AXI\_GP in PS side, the block diagram is showed below: ![image](https://us1.discourse-cdn.com/flex019/uploads/pynq1/original/2X/a/aeaa0e62959dbbf15cfd652fd0cb12c347c1d5c2.png) The code can run at this condition, but I don’t know why. ![image](https://us1.discourse-cdn.com/flex019/uploads/pynq1/original/2X/9/9ee285e9c9a5b9d274fdc2871ac45d9291dc236d.png) ![image](https://us1.discourse-cdn.com/flex019/uploads/pynq1/original/2X/0/035ab40ee254296cc86a5953848667c6e7071c7d.png) I think the overlay.ip\_dict is to choose the IP in my design. Can I use axi gpio to control my IP at the same M\_AXI\_GP in PS side? ---

Yes you can. Without having access to the design or the output of `overlay.ip_dict`, I can’t tell where the problem is in the first design. Perhaps, the address was not assigned. Mario ---

Hi ! I rebuild the design and it works! Thanks for your reply!
