hello, can anybody tell me how to use alt_up_video_dma_draw function in quartus 2018

Hi dlim,thanks for your last reply,

I am using Quartus v18.1, in fact I can use other functions an data are correctly displayed on the screen (like alt_up_pixel_buffer_dma_clear_screen(), and alt_up_pixel_buffer_dma_draw_hline() ).

my problem is that thae data I am reading from the onchip memory are not the actual data, am I missing something ? (like addressing configuration or something).

the .hex file is attached to have an idea (which is an image).

I can provide other information if needed. thanks
