STM32H750B-DK: Can't run TouchGFX with Dual QSPI (2NA17 RW213) and SDRAM IS42S32400J

[Caan]

I have designed a board with STM32H750B-DK With exact same pin configuration with QSPI amd SDRAM connected exactly to the reference board.
QSPI is running properly by viewing using STM CUBE Programmer (External loader selected)
But when I am using touchg GFX sample code it gives Hardfault error I believe that SDRAM is failing. (I have removed the touch screen routine to check the flow of code)

Hello,

Before adding TouchGFX, try to test SDRAM by doing write/read accesses, at least to validate your SDRAM hardware.

The given example of cube h7 is giving errors and it is not working with orignal stm32h750b-dk also
