Vim, Looks like the "video" settings in the bootargs are incorrect to work with the DVSDK 1.30 Production Release. (I am assuming you are using the DVSDK production release 1.30.00.40).
There is a change in the video display architecture to make V4L2 display driver and frame buffer display driver to coexist, so that the application can use frame buffer driver for managing the OSD planes and V4L2 display driver to manage the Video planes. For the DVSDK 1.30 demos to work on DM6446 and DM355, you need to set the video in the bootargs to the following - video=davincifb:vid0=720x576x16,2500K:vid1=720x576x16,2500K:osd0=720x576 x16,2025K davinci_enc_mngr.ch0_output=COMPOSITE davinci_enc_mngr.ch0_mode=ntsc The resolution defined here is used by the frame buffer driver to allocate buffers. The demo applications will then set the required resolution based on the mode set (ntsc or pal). Let me know, how it goes.

At least it is broken with old demos from all the vendors, including TI itself. Fixing those may not be hard at all though. --- On Thu, 5/15/08, Vim Venture <[EMAIL PROTECTED]> wrote: > From: Vim Venture <[EMAIL PROTECTED]> > Subject: Re: Demos not working in SDK 1.3, uBoot 1.2 does not boot > To: "gather bzbz" <[EMAIL PROTECTED]> > Cc: "davinci" <[email protected]> > Date: Thursday, May 15, 2008, 1:34 PM > Thanks for the reply, > > Are you saying that the SDK 1.3 demos just plain don't > work yet? > If that is the case, I should switch back to the SDK v1.2. > > -Vim > > > On May 15, 2008, at 1:26 PM, gather bzbz wrote: > > > NO, u-boot has nothing to do with the IOCTL. it is the > davincifb > > driver > > in the OS that causes trouble.
