Hello @jumman_JHINGA ,

I don't know this board, does it have memory mapped or non-memory mapped flash? To me it looks like your framebuffer is not filled with correct values. Have you checked if if your framebuffer in memory is good? Does your screen has GRAM by the way?

Hii @Osman SOYKURT  thanks for replying. Im using W25Q128 quadspi flash... that is memory mapped.

And before i was getting blurry display... so i corrected the pin mapping of SDRAM in the BSP initialization function... after that im getting cleared display like that.

Im using wave share 1024x600 7inch LCD(f) and its data is here:

https://www.waveshare.com/wiki/File:7inch_1024X600_LCD_DS.pdf

I don't think this display is having GRAM .

I have one more doubt... 

TouchgfxScrachBuffer A and B are in the flash memory section ... do i have to place these buffers into SDRAM section?

hiii @Osman SOYKURT   

I tried Reading & Writting Data on SDRAM & QUADSPI manually. It passed all test cases but still im facing same issue.  please guid me to resolving this issue.

I made silly mistake while configuring FMC. by correcting hsdram1.Init.ColumnBitsNumber = FMC_SDRAM_COLUMN_BITS_NUM_9; to hsdram1.Init.ColumnBitsNumber = FMC_SDRAM_COLUMN_BITS_NUM_8; solved my issue.
