Right now i am using FBdev system to display graphics on BCM chip(MIPS platform) which should use software fallbacks from DirectFB.Later on i 'll add hardware accelerartion also. My framebuffer driver for BCM chip is working fine. I have checked it by running a small example. Also the gfxdriver for directFB is working fine for Video and Image. The problem which i am facing right now is that i am running the fill rectangle example. IT is not filling any color in the rectangle. I am always getting the black screen. Could you plz provide some clue on it ? Also could you plz specify the file name and function in which directFB library is writing into the framebuffer memory the color pixel information?
