Hi,
I got the camera timestamp from v4l2 and found this timestamp is from VI driver. I believe that the timestamp is created by VI according to TSC. My question is how can I convert this TSC time to RTC time in my application?

BR,
Justin

Hi,

For the camera basic functionality first needs to check the device and driver configuration.
You can reference to below program guide for the detailed information of device tree and driver implementation.

Please refer to Applications Using V4L2 IOCTL Directly by using V4L2 IOCTL to verify basic camera functionality.

Once confirm the configure and still failed below link help to get log and some information and some tips for debug.

Thanks!

Hi carolyuu,
I am not asking how to use V4L2. I am asking how to convert to TSC time to RTC time.
Thanks.
