STM32H745 LTDC configuration

[Neboron]

Hi there!

I recently get the STM32H745 Discovery board and am trying to get it working with the LTDC.

I initialized the periphery with cubeMX, due to lack of internal RAM, I reduced the layer resolution to 200x160 pixels and set the background color (255, 255, 0). At the first start, everything is displayed correctly, I specified the address of the frame buffer

HAL_LTDC_SetAddress (&hltdc, (uint32_t)&framebuffer_01, LTDC_LAYER_1);

and change its values ​​to change the color on the screen, but with any settings, the active area on the display always remains black. Can someone help me to solve this problem?

CM7 core Initialise the LTDC.
