I was just about to respond with this image: https://imgur.com/a/3OU0e7D CTRL on the bottom left is connected to Serialeffects and LED is connected to the output port LED_O (LED_O <= CTRL). When I flash the fpga in Vivado with this bitstream, the LED (led M14) does actually toggle with CTRL (switch G15). However, when I flash the fpga with Vitis, the switch does nothing. Any ideas why Vitis may be causing an issue? I've asked other places online, but everyone says the the PS should have no effect on the PL which makes sense to me, but something weird is going on and I'm not really sure how to debug it.

Thanks for the response. Are you saying the combination of 'CTRL' made external and its reference in the XDC, plus having the GPIO block with its output sws_4bits is correct?

Hello, everyone. I am having difficult finding a guide or solution to this problem. I would like to simply connect a switch (G15 on the Z720) to my custom IP that should toggle a Clean or Distortion signal. For some reason I am unable to insert a link to the Block Diagram: https://imgur.com/a/D3uOchd In the diagram you can see that I had originally just made CTRL external and added it to the constraints file for pin G15, but this did not work. I'm think that I need to instantiate GPIO in Vitis to use this method, but so far I haven't had any luck. My next thought was to use the AXI_GPIO block and somehow tie it to both sws_4bits and the CTRL port on Serialeffects, but that is what I cannot figure out how to do. Does anyone have a resource for learning how to do this? I'm open to any suggestions, as I would eventually like to use the 4 switches on the board to control different audio effects, such as chorus, echo, etc.
