 i dont know what is causing it , . display is running at 11 mhz.

i am using nucleo H7A3ZI-q dev board with cortex M7

i asked in lvgl no response from them :sad_but_relieved_face: any help here 

i also tried to fill iw with two colors 50-by 50 theni got this

if i put 0x24000000 i get the misaligned one . but now the issue is if i integrate LVGL now while the startaddress is (uint32_t)framebuffer , i get nothing in display , if i chnage that to 0x24000000 i get the misaligned output of LVGL
