No LCD screen problem

Hello,

Please help me about below.

I confirmed that the project source code that displays the screen using the touchgfx graphic library on the stm32f429 discovery board works normally. A new board was manufactured using DT024CTFT instead of the LCD used for the discovery board. Since the driver IC of the LCD used in the discovery board is also ILI9341, I tried to run the program after modifying the source code for the new board only for the SPI communication line, but the LCD backlight turns on, but the UI screen I wrote does not appear. I am attaching the source code of the LCD initialization part that I wrote and the circuit diagram of the LCD side of the new board, so please review it and suggest a solution.

Best Regards,

Paul
