Part Number: AM5728

Tool/software: Linux

Hi,

I use ti-processor-sdk-linux-am57xx-evm-05.03.00.07 SDK,I can't detect /dev/video1.

I understand that the device name of the camera is /dev/video1 and /dev/video0 ,and display device name is /dev/drm in example-applications/dual-camera-demo-1.0/loopback.c.

As shown below:

I want to know how video0 and video0 are defined in the driver file.Please tell me where they are defined.Then I can change the driver file.

I am very grateful that you can help me.

Hello,

On AM57x EVM, only one camera input is supported with dual camera demo (/dev/video1). /dev/video0 is VPE note.

There is no need to change the dual camera demo.

I think your problem is that the /dev/video1 is not detected.

Are you using camera module with the EVM? What the output of ls /dev/video*?

If yes, what is the camera module that you are using(ov1063x or mt9t1x based)?

Please boot the board and execute -
dmesg | grep mt9t

If you see no logs, then execute
dmesg | grep ov10

If there is no logs again let me know.

In this thread :

You could find explanation about the notes.

Here is the VIP user guide also:

Hope this helps.
