GPIO demo on Nexys Video


I am trying to synthesize the GPIO demo for the NexysVideo and I am getting a synthesis error that I need some help with. The error is:

<path>/NexysVideo/Projects/GPIO/src/ip/charLib/charLib.dcp is not a valid design checkpoint

Has anyone else seen this and know how to fix this?

I am using Vivado 2015.3 if that helps. I'm including a an image of the full output

Hi dnappier,

Just to verify, you are using the project zipped in this tutotial https://reference.digilentinc.com/learn/programmable-logic/tutorials/nexys-video-user-demo/start. I was able to generate a bitstream without an error in 2015.1, 2015.4 and in 2016.2. I don't have 2015.3 downloaded. First I would suggest to copy the project to C:\ and re-try generating bitstream from there. You might want to re-download the zip file to ensure nothing was accidently changed when doing this as well. 

thank you,
