Hi everyone,

Do anyone know, In Blaze ICS how camera HAL will interact with the camera driver?

And In omap4430 Blaze ICS how the CortexA9 will communicate with SysM3 and AppM3?

CameraHAL has a class OMXCameraAdapter which acts as OMX client. The client makes OMX standard calls to the component like GetHandle, UseBuffers etc.

Camera driver is abstracted inside OMX Component. The component (which resides on Ducati) translates OMX level calls to cmaera driver and framework controls.

Thanks for your answer. I have one more query that is mentioned below

The OMX Component in which camera driver is abstracted, it is written in which file,please let me know the filename.

And In blaze ICS source, camera uses ISS driver or V4L driver??

Please look at source files inside the folder

hardware/ti/omap4xxx/camera/OMXCameraAdapter/

Camera driver is not V4L or ISS (not sure what it means). The driver is based on OMX.

Hi.. I'm working on Android Camera HAL in Pandaboard - Android Jellybean. I want to use OMX for still/video capture. I could not find where camera device node is opened. Where do camera device node name specify ?
