OV2720

Chad Hewitt

I am able to get Ducati to communicate with the OV2720 on custom omap4 hardware but ICS Android hangs on bootup with repeating logcat message

I/ServiceManager( 165): Waiting for service media.audio_policy...
W/AudioSystem( 165): AudioPolicyService not published, waiting...

The OV2722 driver was ported with slight modifications from omap5 Ducati. There are also DCC errors in the attached Ducati trace.

Any help or insight you can give is greatly appreciated.

Thanks

DCC Init is failing from A9 side and because of that CameraHAL cannot get properties. This makes mediaserver fail and you see audio errors. Please check the following:

1. Do you have /data/misc/camera folder on Android FS

2. If yes, what are the contents

3. What is DCC URI defined for OV272x?

I have BUILD_SEN_OV2722 defined in build.h instead /data/misc/camera. When I undefine BUILD_SEN_OV2722 and put data in /data/misc/camera/R2_MVEN001_LD0_ND0_IR0_SH0_FL0_SVEN001_DCCID47 I get similar results.

The URI is defined as R2_MVEN001_LD0_ND0_IR0_SH0_FL0_SVEN001_DCCID47 in new_camera.c CameraModules[]/.

The DCC files were ported from omap5 ducati.

Just to collect some information, Can you tell me what version of software are you using? is it 4AI1.4? or 4AI1.7? and what is the version of OMAP5 release from where you get the DCC files? I mean only if it is in the public side.

I'm the FAE working with Chad. I provided the Ducati source from 5AI.1.13p1. I'll let Chad comment on which ICS version he's using. If there's a different version of the Ducati that I should provide let me know so I can post to CDDS for Chad.

have you verified that the sensor is working and is able to stream data to OMAP? In cases like these we have seen that most of the time either HW connections are faulty or the driver does not program the sensor and CSI correctly. DCC should be the last thing to worry about.

Thanks I was able to get OV2720 working by moving it to another slot and using the DCC files from OV5650. Still more work to be done but at a great starting place. Thanks for the help.
