Hello all,

I am using DVSDK version 1_30_01_41, When I run dm6446 decode demo, i am getting following errors.

Failed to get the requested screen size: 720x480 at 16 bpp

Failed ioctl FBIOPUT_VSCREENINFO on /dev/fb/0

my bootargs are

video=davincifb:vid0=720x576x16,2500K:vid1=720x576x16,2500k:osd0=720x576x16,2025K davinci_enc_mngr.ch0_output=COMPOSITE davnici_enc_mngr.ch0_mode=ntsc console=ttyS0,115200n8 noinitrd rw ip=10.10.10.202:255.255.255.0:10.10.10.101 root=/dev/nfs nfsroot=10.10.10.154:/dm6446/filesys,nolock mem=120M

can any one suggest me a way to fix this?

Regards,

Usually this sort of error would stem from a problem in the video options of the bootargs, but yours look to be right on so there must be something else going on here. When you boot the kernel do you get any errors or warnings relating to the display driver?
