UP VGA Pixel Buffer problem

Hello ronix5000,

Have you look at my screenshot of my system build?

Make sure vga_ctrl clock is set to 50MHz (other components connected to it will need to be at 50MHz too).

Pixelbuffer needs SRAM to work. Pixels will actually be stored in this SRAM. Last thing, pixelbuffer needs its start address (in the properties) to be set to base address of SRAM.

I have not made any changes to design files.

If you want to test if vga controller is working, you can try to connect only the character buffer (without alpha_blending and SRAM).

Hope this will help.

Regards
