Thanks for the reply, mrbietola.

I did try test_pattern_generator. I added 3 channels to the mixer, two were from test_pattern_generator, one were from my VGA data channel. The only thing the CPU did was to switch between these channels according to key press. I can switch between test_pattern_generator channels and display them correctly, but the image of my VGA data channel doesn't display right (I mean a black screen was shown) if I switch to this channel. If I remove the mixer and the CPU, leaving only my data channel in the path, then the image is good again.....
