Re: Demos not working in SDK 1.3, uBoot 1.2 does not boot

Thank you Sneha, that cleared up some confusion for me about the V4L2driver vs davincifb driver.

The bootargs you listed are the ones I started with, copied fromsprue66d. I still got the same "Decode Error: Failed ioctlFBIOPUT_VSCREENINFO" with those bootargs. I later changed thebootargs to the 720x480 size, but this does not seem to affect theproblem I'm having.

Yes, I'm using DVSDK 1.30.00.40, no modifications to any code, and I'msimply trying to get the demos to run. Like I said earlier in thethread, the only difference I could find in my setup is the version ofuBoot. I have uBoot 1.1.3 working, but uBoot 1.2 does not seem to runon my DM6446 EVM. I find it hard to understand how uBoot could havean effect like that, but that's where I stand right now.

Does anyone know how to tell from the device/date code marked on thedavinci chip if it is an alpha, beta, gamma, or delta version? Thatdoesn't seem to be documented. I'm wondering if I have an older chipthat has compatibility issues.

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 usingthe

DVSDK production release 1.30.00.40).

There is a change in the video display architecture to make V4L2display

driver and frame buffer display driver to coexist, so that the

application can use frame buffer driver for managing the OSD planesand

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.

Thanks
Sneha

Yes. At least it is broken with old demos from all the vendors,
including TI itself. Fixing those may not be hard at all though.

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.

Hi everyone,
I am using the SDK v1.30 release on the DM6446, and

none of the demos

will run for me.
When I run the decode demo, I get the following
error.

----------------------------------------------------------

[EMAIL PROTECTED]:/opt/dvsdk/dm6446# ./decode -v data/
davincieffect_ntsc.m2v
Decode demo started.
Decode Error: Failed to get the requested screen size:

720x480 at 16

bpp
Decode Error: Failed ioctl FBIOPUT_VSCREENINFO on

/dev/fb/0


Total I-frames: 1, P-frames: 2, B-frames: 0,

IDR-frames: 0 rejected: 0

[EMAIL PROTECTED]:/opt/dvsdk/dm6446#

----------------------------------------------------------


Similar errors occur with the other demos.  I am

currently using uBoot

1.1.3.  The release notes for SDK 1.30 say that an

upgrade to uBoot

1.2 is needed, but my DM6446 EVM will not boot with

uBoot 1.2.  It is

unresponsive and I have to revert back to 1.1.3 with

DVFlasher to get

a proper boot.  I'm not sure if these 2 problems

are related.  Could

the version of uBoot affect FBIOPUT_VSCREENINFO?

My boot-time video args are
set as:
video
=
dm6446fb:vid0
=
720x480x16,2025K
@0,0

:vid1=720x480,[EMAIL PROTECTED],0:osd0=720x480,[EMAIL 
PROTECTED],0:osd1=720x480,[EMAIL PROTECTED],0


Has anyone else bumped into this problem?
