Hi Denis,I am writing gfx driver for DirectFB on BroadCom chip.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?Thanks in Advance.kaka

That's normal. If you want runtime you have to create a timer or register idle or timeout functions.

Simply/weakly put: it should not return before the application is quit.
