I'm having an issue with all of the digital IO on PMOD port JB.
When we build a simple design that connects a constant value generator to an 8-wide output port, and use the Zybo xdc file to connect the PMOD outputs to the generator, we get no output on any of the JB logic pins. JC, JD, JE all behave as expected with their pins reading 3.3V.
Is it possible to damage only those pins? Since they belong to the IO Bank 34 along with pins that we can show work, it seems strange that they would all fail together, but other pins on the IO bank wouldnt.
Perhaps someone that knows more about the board outputs could lend some insights.
