Zybo Z7 Pcam 5C Demo - Warnings

Question

I'm trying to run the Zybo Z7 Pcam 5C Demo...  

i'm really new at this, the instructions say:

**********************************************************

To generate the project:
1. Open Vivado 2017.4
2. In the tcl console, type "cd [this directory]/proj" and press enter.
3. Type "source ./create_project.tcl" and press enter to generate the block design for the project.

To run the demo from SD card:
1. Copy bin/BOOT.bin to the root of your SD card.
2. Set the boot jumper on the Zybo Z7 to SD.
3. Insert the SD card into the Zybo Z7 and power it on.

**************************************************

I'm using Vivado 2017.4 and i've copied the board_files to vivado software.

 

After the point 3. (Type "source ./create_project.tcl")

I get 7 warnings about some pins...    am im doing something wrong here?  I'm a newbie.

 

Can you help me out to make the demos work, thanks in advance!

Hi @Azzor,

Welcome to the Digilent forums.

I downloaded the zip file for Vivado 2017.4 from the release page here. I opened Vivado 2017.4 cd'd to the correct folder and opened the project. I then generated a bitstream without issue.

I have attached a screen shot of this.

Are you using a different version of Vivado?

Best regards,

Jon

To add a little bit to what Jon said, these warnings appear to be ignorable. They all relate to design choices made when connecting custom IP in the block design.

Typically, even when designing with Xilinx IP, many warnings are seen in the project. These messages are there to help get information on why something may be causing bigger problems later (errors, critical warnings, something not working in actual hardware). Note that even some critical warnings may be ignored.
