I have a project to display some text using touchgfx. I'm using a custom H750 board, a LCD-TFT display. My LTDC, DMA2D, SPI is working fine but when i try including touchgfx, every time the framebuffer gets zero.

 I'm not using rtos, my touchgfx process is included in while(1). After debugging through IAR, i've run it and below image is from the .map file. I've also checked the memory address, it is getting zero only.0693W000000WouwQAC.png

I'm getting this memory management fault. An MPU or Execute Never (XN) default memory map access violation has occurred on an instruction fetch (CFSR.IACCVIOL, MMFAR). Exception occured at PC = 0x24026b84, LR = 0x800154f . I don't have an external memory so i'm using "stm32h750xx_flash_rw_sram1.icf"
