7inch AT070TN94 LCD and STM32F429 on STM32Cube Setup on custom board?

Hello there,

I have a custom board for STM32F429BIT6 and want to setup a 7inch AT070TN94 LCD in STM32Cube. I checked all the manuals and learning on the web, almost all of them are about Discovery boards with some special LCDs and drivers.

So I started on my self to see if I can make it work, but there is no response.

Here what I did:

FMC configurations for SDRAM (W9825G6JH-6) as picture.

DMA2D configurations as picture.

LTDC configuration as below:

Finally I did enable CRC and set the clock on 180MHz.

I haven't enable STemwin or TouchGFX yet, I want to setup the LCD itself first and I expect LCD turn on in Red (as background set), but it's not working like that.

Tanx for you answers
