2009-07-23 16:36:57     Missing intialization in bfin_adv7393fb framebuffer driver

Marshall Seaborn (UNITED STATES)

Message: 77976   

 

I'm attempting to use the bfin_adv7393fb driver int 0 FS ITU-R 656 mode and after debugging a video output problem I noticed that there appears to be missing preamble and blanking data.  The xmodify and ymodify for the vertical blanking transfers are 0.

 

Am I missing something or don't the video encoders require the preamble and blanking data for synchronization?  Or does this driver just not support 0 FS ITU-R 656?

 

Thanks,

 

Marshall

It uses 16-bit RGB565 in 2 FS external framesync mode - generated by the ADV7393.

So the framebuffer memory only includes active video pixels.
