Other Parts Discussed in Thread: DM385

I want to use the dual sensor (IMX322 + IMX322) on DM385 for BlackBox application.

The data by the camera interface passes through the ISIF. H3A data is available in this case.

But the data by the video interface passes through the HDVPSS instead of the ISIF.

So I can't get H3A data for this interface.

Is it possible to get H3A data for the video interface like the camera interface?

You could get the H3A data for both the channels if either both the channels are captured from hdvpss or one of the channels is captured from CSI2. If you have parallel input, then h3a can be used only for one of the channel as this path is used in on the fly mode..

Thank you for prompt answer :D

As shown below figure, I know how to get H3A data from ①CAM but there's no idea for ②VIN0.

Could you please explain to me how to get H3A from ②VIN0?

Hi Kim,

As you can seen in the diagram, once the input comes from the video Port, the path is completely blocked for the ISS capture. It can not be used for getting H3A data for VIP sensor. When you use parallel input to capture data, it uses path video port -> isif -> memory. which means isif, which gives input to H3A, is blocked ofr one sensor, it cannot be used for the other sensor.

Thank you for answer.

I'm trying to get H3A data of the two video input respectively.
