DM6446 osd issue

Can you make sure that your u-boot bootargs settings match what is described in the corresponding DVSDK Getting Started Guide?  The required settings changed from mv4 to mv5 releases and this is reflected on the updated GSG for DVSDK 2.0

The bootargument iam passing according to the GSG document for DVSDK 2.0 is

" setenv bootargs video=davincifb:vid0=0,2500K: vid1=0,2500K:osd0=720x576x16,2025K davinci_enc_mngr.ch0_output=COMPOSITE davinci_enc_mngr.ch0_mode=$(videostd) console=ttyS0,115200n8 noinitrd rw ip=172.28.8.30 root=$(root) nfsroot=$(nfshost):$(rootpath),nolock mem=118M"

But still the result is the same i am getting the following error
Error: Failed to create osd window device
Error: Failed to create UI

Is this a driver issue ?....or is this problem with the interface or any arguments?..what exactly can yu suggest...please reply soon

hai juan

well some success i could see the osd screen now[:D]

well i tried booting it with following args

setenv bootargs video=davincifb:vid0=720x480x16,2025K@0,0:vid1=720x480x16,2025K@0,0:osd0=720x480x16,1350K@0,0: osd1=720x480x4,1350K@0,0 davinci_enc_mngr.ch0_output=COMPOSITE davinci_enc_mngr.ch0_mode=$(videostd) console=ttyS0,115200n8 noinitrd rw ip=172.28.8.30 root=$(root) nfsroot=$(nfshost):$(rootpath),nolock mem=118M

After booting i did

root@172.28.8.30:~# fbset -fb /dev/fb/1 -xres 720 -yres 480 -vxres 720 -vyres 1440 -depth 16

root@172.28.8.30:~# fbset -fb /dev/fb/3 -xres 720 -yres 480 -vxres 720 -vyres 1440 -depth 16

And upon running the decode demo with the osd option ,

./decode -v /opt/dvsdk/data/videos/davincieffect_ntsc.m2v  -o

I am able to see the 2 layers of OSD screen , But i am not able to see the decode video as am getting the following error

DavinciDisplay DavinciDisplay.1: Display Manager failed to allocate layer
DavinciDisplay DavinciDisplay.1: Unable to configure video layer for id = 0
Error: Failed to create display device
decode: ce/Vdec2.c:114: Vdec2_process: Assertion `Buffer_getNumBytesUsed(hInBuf) ' failed.

Can you please tell me how to resolve this isssue .....it is very urgent juan we have our deadline nearing .

I believe the key is the size you are assigning the video windows in your bootargs; per the GSG, these should be

"video=davincifb:vid0=0,2500K:vid1=0,2500K

hey hi juan,..

 i am glad its working now i was not trying with 480 resolution .now the video and the osd are coming. thankz a lot.btw weree will the ui code for the remote>?

hai juan,

i am not getting a screen which shows the picture of the remote control after booting of the board so that i can set the remote as per the GSG document.

And am also not able to see the main menu screen with which i can select the demo. Osd will only come while runing the application on command line ?

please update me wth neccsaary details.

interface demo (which displays the menu options you can control via remote control) is normally launched automatically when booting from HDD, but does not launch automatically when booting via NFS (althought it is really dependant on the file-system init scripts).

You can login to your target evm and cd to appropriate directory ( /opt/dvsdk/dm6446) and launch the demo manually

   % ./loadmodules.sh

   % ./interface

hai juan,

can you tell me how to add the INTERFACE application in the4 start up so that it will start once the board gets booted up. i tried adding it in the /etc/init.d/rcS file but it showed me error that it cant find the modulees,

so i added the loadmodules.sh application  in the rcS file , but still error is coming wchich says it cant niether insmod nor mknod . how will i add the application to run at initial boot time??  

When you boot from your HDD, you should find a script under

/etc/init.d/dvevmdemo

This script launches the interface demo automatically when you boot from HDD.  You can add the same script to your NFS based-file system under the same path.  I am attaching an old copy of this script I still have laying around (not sure if it has changed on new DVSDK), but you can give it a quick try.
