How to implement DMA2D?.

[anand-010]

I've followed this guide https://forum.lvgl.io/t/how-to-configure-the-dma2d/3407/5 and added

/* 1: Enable GPU interface*/
#define LV_USE_GPU 0 /*Only enables gpu_fill_cb and gpu_blend_cb in the disp. drv- */
#define LV_USE_GPU_STM32_DMA2D 1
/*If enabling LV_USE_GPU_STM32_DMA2D, LV_GPU_DMA2D_CMSIS_INCLUDE must be defined to include path of CMSIS header of target processor
e.g. “stm32f769xx.h” or “stm32f429xx.h” */
#define LV_GPU_DMA2D_CMSIS_INCLUDE <stm32f7xx.h>

but i've got this error.

do you have any idea how to implement dma2d?.

I've changed every DMA2D_OPFCCR_RBS_Pos fro RBS to CM like DMA2D_OPFCCR_CM_Pos now all errors gone but still has the same lag. i don't know how two elf files combined together. i am missing something?.
