As we have Parallel RGB LCD and we tried integrating with STM32H743 controller and using touchGFX we are trying to display the image but nothing is displaying on the LCD so what may be the issue?

I looked into GPIO configuration and it's correct..
Then I will look into this framebuffer address .
Thank You

Is that possible to change the RGB configuration to BGR in STM32cubeMX or touchGFX?

No i mean only in your code , when your display have too config interface connected SPI or I2C, you send some commands and set this.

There should be a memory window where you can just point to the address of the framebuffer you're interested in and look at the raw data.

Your project is configured to 16bit touchGFX framebuff this equal to RGB565. You need understand how this work, in memory dont exist 255 0 0.
