ERR when external SDRAM & NandFlash with FMC

Junde

Hi there,

I have a touchGFX project with STM32F429BI, which uses the external SDRAM for the buffer, and the Nand Flash for the image.

Both SDRAM and Nand Flash work well when turning off the other.

But when I enable LTDC, the Nand Flash always gives an error when reading/writing it.

It seems the access to Nand Flash and SDRAM is conflicting.

Does anyone know how to deal with it?

Thank you.
