Dear Sir,

I have Imx6qsabresd(evaluation board which is purchased from the freescale ).I download the Android lolipop prebuilt image from freescale(L5.0.0_1.0.0-ga).which is running on my board.

but i couldnt find out camera in the OS. i connect camera on my board. from the release note i can understand that this prebuilt image support camera.

what is the problem in it why i cant find out the camera in there.

if OS support camera feature means i can see camera icon on my display .

please help me to solve this issue.

Do you mean you can see other apps (such as clock, calculator) but no camera apps?

do you see the camera is up in logcat?

If camera is not connected than above log appears.

If you are using SABRESDP board than camera will be detected.

What is output of "pm list packages "?

Thanks

The error is showing the driver try to read the camera ID from the ov5640 register.

Seems the camera is not attached well on the sabresd board. So the driver cannot read the camera ID via I2C.

Maybe you can download the schematic for reference.

SABRE Board Reference Design|Freescale

--> iMX6_SABRE_SDB_DESIGNFILES

Design files, including hardware schematics, Gerbers, and OrCAD files.

In the page 8, connector J9 is for ov5642, and connector J5 is for ov5640 mipi.

And I attached a picture for you that the SabreSD board is connecting two cameras.
