  1. Hi @jpeyron, Thank you for your response! I am using a Nexys4 DDR board. I did not find any problems despite the warnings, the generation of the bitstream did not fail. It was just strange that the warning did not occur with the PmodSD.. I had to ask whether there was a hidden connection between them. Thank you!
  2. Hi everyone, I am working on the tutorial of the Pmod Wifi (found here https://www.youtube.com/watch?v=KTeTMv3oiPw) and I don't really understand the role of the Pmod SD. From what I saw, in the tutorial, the Pmod SD is used to hold the static HTML pages that are then loaded in the browser. I would like to try something simpler, basic Wifi communication, and I wanted to leave out the Pmod SD IP from the block design, but then I got critical warnings at the bitstream generation. No problems arise when the Pmod SD IP is added, though. So I was wondering, is there a more important role to the Pmod SD that I did not seem to get? The critical warnings say: [IP_Flow 19-3298] Detected external port differences while upgrading IP 'PmodWIFI_axi_quad_spi_0_0'. These changes may impact your design. [IP_Flow 19-3298] Detected external port differences while upgrading IP 'PmodWIFI_axi_gpio_0_0'. These changes may impact your design. [IP_Flow 19-3298] Detected external port differences while upgrading IP 'PmodWIFI_axi_gpio_1_0'. These changes may impact your design. I am using Vivado 2015.4. I would appreciate any ideas on how these modules work or what I could have done wrong. Thanks a lot!
