Problem in using Li-Vid365 input board.

[aziz]

[Pascal's comment: this topic has been split from a previous subject (see "Booting Leopard365 board using SD card")]

Hi Pascal,

I will do the same in coming few days.

I have got a Composite video input board LI-VI365. I connected it and soldered R196 and R197 resistor as mentioned at many places but still v4l2 src is not working. Do I need to add/change anything to make this work? Can dvsdk_3_10_00_19 be the issue?

Also have you tried connecting a USB modem to the leopard board?

Awaiting reply.

Thanks
Aziz

Hello Aziz!

First question, tell me about your configuration. Do you have a TV monitor on the composite output
(or DVI if you use this output)?
Now when you boot, do you see the RidgeRun logo on this monitor? If not, then check if the bootargs
are right (i.e. check that if you use a video composite monitor, your args mention "composite".

In my case, I spent a lot of time to make it boot, but once it did, it worked almost at once.

I have still no time to experiment with the new software (3_10_xxx), but I don't think it should change.

I forgot to mention: did you enable the LiVi365 video driver? If not, then you have to configure it.
In make config menus, go to the kernel, and look for the multimedia devices. I don't remember the
exact path in the menus, but you have to enable this driver. The default doesn't work. Once you
enable it, you will get the image probably right away. That was the only missing part in my case.

Hi Pascal,

Thank you for your reply.

1. I am using DVI and while doing the config I have set the output at DVI and it reflected in the bootargs. But I am not able to see anything on the monitor. The bootargs it says vid0=off and vid1=off and when I check for the video devices it just shows /dev/video3 and /dev/video2. How to I switch on video0 and video1, can this be the root cause?

2. I have enabled the driver, have a look at the screenshot. I am enabling the chip which is present on LI-VI365 board.

3. Have copied my log, if you find anything different then please let me know.

Hello Aziz!

So you don't have output at the monitor, but does it boot normally? I mean, do you
reach the Ridgerun logo on the text terminal? Apparently the log ends normally.

If it ends normally, then try to go to /examples and launch your video application.
If there are errors messages, it will give you some hints about what to do.

Beside this, I cannot be absolutely sure of what you should observe since we don't
have exactly the same environment.
