Other Parts Discussed in Thread: DM3730, ADS7846, TVP5146M2, TVP5146

Hi,

I am working on DM3730 Mistral EVM.
I am trying to run the video loopback application from composite input(CVBS) to LCD output.
I am using DVSDK_4306 - Linux 2.6.37

For this, I am running the following application from the filesystem:
/usr/share/ti/ti-dmai-apps/video_loopback_copy_dm3730.x470MV -O lcd -I composite

When I run this application, I see the following error messages:
Capture: Current Input: camera
VIDIOC_S_INPUT: Invalid argument
Capture: Input changed to: camera
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
.

Hi Bharath,

I read in the last rows in your description that the demo works fine with the previous dvsdk (4.02.06) therefore I compare the sources of video_loopback_copy in both dvsdk version and I discover that there are no differences. Have you made some changes in the source code?

Hi Tsvetolin Shulev,

Thanks for your fast response.

I have not made any changes in the source code of the both.

Regards,

Hi Bharath,

Could you make the following tests:

1. Try to start video_loopback_copy from dvsdk-4.02 under dvsdk-4.03

2. Try to start video_loopback_copy from dvsdk-4.03 under dvsdk-4.02

Share the results please.

Hi Tsvetolin Shulev,

Please find the results of the above mentioned tests:
1. starting video_loopback_copy from dvsdk-4.02 under dvsdk-4.03:
root@dm37x-evm:/usr/share/ti/ti-dmai-apps# /usr/share/ti/ti-dmai-apps/video_loopback_copy_dm3730.x470MV -O lcd -I composite

2. starting video_loopback_copy from dvsdk-4.03 under dvsdk-4.02:
root@dm37x-evm:/usr/share/ti/ti-dmai-apps# /usr/share/ti/ti-dmai-apps/video_loopback_copy_dm3730.x470MV -O lcd -I composite

As we can see, getting the same error message on both.

Can you please explain me why there are only 3 video nodes in kernel 2.6.32 whereas kernel 2.6.37 has 9 video nodes under /dev?
Also what does v4l-subdev0-8 device nodes represent? I cannot see these nodes in Kernel 2.6.32.
The kernel 2.6.32 is having omap34xxcam.c and omap34xxcam.h camera driver files. However, in the Kernel 2.6.37 the omap34xxcam.c/omap34xxcam.h files are not
available.
How does the camera and V4L2 framework differ from 2.6.32 and 2.6.37?

Hi,

This is to inform you that the above issue is resolved.

There was a small change in the application required.

Please find the attached working saMmaploopback.c.
