    For the Protocol / SPI-I2C /Spy mode you should specify the approximate (or highest) protocol frequency which will be used to filter transient glitches, like ringing on clock signal transition. The Errors you get indicate the signals are not correctly captured. - make sure to have proper grounding between the devices/circuits - use twisted wires (signal/ground) to reduce EMI - use logic analyzer and/or scope to verify the captured data / voltage levels at higher sample rate at least 10x the protocol frequency Like here in the Logic Analyzer you can see a case when the samples are noisy:

    Hi, I indeed have a sd card with the correct files in. Anyway, i found a way to make it work without the LVLSHFT here : https://github.com/NicholsKyle/ECE387_SimonSays/wiki/My-Design#schematic-drawing. Now I'm struggling to display correctly on the MTDs, it's certainly my code the problem. But thanks for your help @jpeyron.

    hdmi ip clocking error

    Hi @askhunter, Please attach a screen shot of your vivado block design. Have you tried changing the MMCM to PLL in the DVI2RGB IP Core? best regards, Jon

    Hi @askhunter, I believe that you would only need the more recent DVI2RGB IP Core and the IF folder in the Vivado library. best regards, Jon
