Problem with connecting 8 bit display to STM32H743ZI2

[STara.5]

Hi. everyone. I tried connect 8 bit display (ili9341) to nucleo STM32H743ZI2 board. I used to 8bit LCD interface FMC for it, but image didn't appears. I connected this display to stm32f407 and l4 series without problem. And I'm sure that my driver is correct.

Would you detail about the connection between your LCD and FMC interface on NUCLEO-H743ZI? for me the FMC is not supported by default on Zio connector?

Let me explain problem more detail. I have the display from Arduino shild like i show on picture. I configurate FMC in STMCubeMX for work with LCD 8 bit . I connect all the wires as CubeMX show me and set needed timings. But for exsample. I want to fill the display with a different color, nothing happens. P.C. I tested my driver on another board and in theory I had to change only address FMC (i use ADDRESS_COMMAND (0x60'00'00'00) ADDRESS_DATA (0x60'00'80'00) )

Understood. Did you read LCD controller ID before writing display data to GRAM in LCD controller? it could be a way to check if any issue in HW connectivity point of view or if any FMC bus timing mismatch between MCU and LCD. The FMC bus monitoring by a oscilloscope may be needed to understand the root cause.
