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.
