use 8 megapixel camera on omap4460

I use 8 megapixel camera OV8825 on OMAP4460 and modified ducati imx_060 for using OV8825.Now can work on preivew and record mode, but can not work on capture mode. Any idea?

OV8825 is a RAW RGB 10-bit(BGGR) camera.The ducati debug messages are below:

    What resolution capture are you trying? IMX060 is 12MP which can not be supported from an 8MP sensor. Ensure that image capture resolution passed from HLOS is <= 8MP

    sensor drivers need to have different CSI, ISP and sensor settings for preview and capture modes. Please make sure that you have made necessary modifications for all the parameters in the sensor driver. 

    There are 2 parts to this problem -

    1, sensor mode + CSI settings

    2. ISP+JPEG Processing pipeline on OMAP

    The second one is easy to validate. You can keep the sensor in preview mode settings and use those settings for capture. Make sure that capture resolution is set <= sensor output resolution. For e.g. if you use 2x2 binning sensor resolution is 2MP.

    Once this is done you can define a full resolution mode and see if CSI I/O is able to grab the image from the sensor before processing it in ISP.

    Once this is working

    In fact, Capture and Preview mode use the same setting for 1600x1200 resolution, but only can preview,failed to capture.I also modified from OV5640 camera, but result is the same.

    I guess the problem perhaps about camera dcc binary, but I don't know how to generate dcc binary for camera.

    if you are judging by the logs, DCC errors you are seeing are harmless.

    the logs show imagebuf equal zero, the imagebuf address sure be a none zero value when capture sucessfully.why the imagebuf address equal zero?

    Probably memory allocation is failing. I will be happy to review your driver changes. If possible, please share your code through your  TI representative. Do not attach code on this forum because Ducati code is not opensource.

    I tested nearly the same code and resolution for OV8825 and  OV2655  and OV5640，OV2655 and OV5640 camera could capture successfully. OV8825's difference is only native register setting and  OV8825_desc.c setting for sensor type to  SENSOR_TYPE_BAYER_RAW10 COLPTN_BGGR. Any idea?

    The ducati version is Linux_27.IS.1_Ducati which I used.

    How to share code through you TI representative?

    when I replaced first camera definition in the file of camera_descriptor.c, swap OV2655 to first camera and OV8825 to second camera. after this swap ducati generate error information on debug message as below:

    how to resolve above error?

    what is the native resolution defined for these sensors in xxxx_defs.h? 

  • 0 in reply to Mayank Mangla
    Prodigy 85 points

    All defined 1600x1200 resolution in xxxx_defs.h

    #define OVxxxx_ACTIVE_PIXELS_H 1600 
    #define OVxxxx_ACTIVE_PIXELS_V 1200 

    #define OVxxxx_NATIVE_SIZE_H 1600

    By the way,how to use ducati ISS ISP H3A function for camera?

    That functionality is already implemented in Ducati framework. You don't need to do anything extra. Just get your sensor running and 3A will be working automatically.

    You will need to tune 3A for optimum image quality, but that is a different topic all together.
