Hello.

I'm trying to run TFT 480x272 RGB.

SDRAM works, PLL3 is started, but as soon as I add to the project the LTDC program goes into the software error.

In the examples of the CubeMX, everything is written without using it.

Who can tell the reason.

An error in CubeMX?

At this point in the HAL library, the code drops.

HAL_StatusTypeDef HAL_LTDC_Init(LTDC_HandleTypeDef *hltdc)

{

.................................................

hltdc->Instance->GCR &= ~(LTDC_GCR_HSPOL | LTDC_GCR_VSPOL | LTDC_GCR_DEPOL | LTDC_GCR_PCPOL);

..............................................................................

}

Today I created the project anew.

Surprisingly, it all worked.
