frame buffer problem

Nice to meet you all. New to this forum and recently started working on Linux.

Here is my problem. I'm working a Set top Box with Linux Embedded. The framebuffer of this box supports for 16 bits per Pixel. When I try to draw something (setting few colors) it is NOT displaying any thing. Now when I do the below procedure then I see something on screen.

1. Receive the Variable Screen Info

2. Forcibly Set the Pixel size to 32 bits.

3. Write the Variable Screen info using IOCTL with FBIOPUT_VSCREENINFO

4. Again set back the Pixel Size from 32 bits to 16 bits

5. Do step 3.

After following above 5 steps then I'm able to see something.

Does anybody face this problem please discuss and please guide me if anybody have a solution.

Thanks in Advance.

STB Engineer.
