Hi.

I have tried to generate a project using STM32Cube for the STM32469-DISCO board. but it seems that the LTDC module is not initializes. All registers is zero.

I have tried compare with the demonstration project for the board, and here some of the registers in the LTDC module change values from cero when the peripheral clock is enabled. But in my Cube project they are not.

Are there any other things that has to be set up besides the clock before the LTDC module is enabled.

I have attached the clock config from Cube and a screen shot from the Keil debugger.

Solved.

The PLLSAI clock was not initialized by Cube. I think that Cube forgets it when the USB clk is not used.

However, still no picture on display . . . .
