Hey there,

First of all: great project 👍

Now my problem: I built the setup and onece/twice/sometimes was able to at least get the splash screen up. When my wiring was wrong it even showed me that.

But currently I'm not able to get at least a pixel out of the setup.

I don't really know what's the expected behaviour or the minimum conditions for the FPGA to output a picture.

Is it sufficient, that I simply connect the HDMI-Port and power up the FPGA or are there some signals that are mandatory to be present at the FPGA to output for example the splash screen?

Cause I already rewired my whole setup except of the HDMI-Port as continuity at least says that everything is correct here.

Thank you 👍

Hi,

l think you are successful to set up and show.

I use the test pattern to test, there are always two block shown.

Is my screen not supported? or something wrong? (I can not set up 720X480, just use 640X480)

Did you have some ideas?
