Camera ISP Configuration

Other Parts Discussed in Thread: OMAP3530

Hi all,
 
             I am using CM-T3530 Processor with Linux kernel 3.0.68 (Kernel is patched with CM-T3730 patch file) which is avalible in CompuLab websit. I have configured the Linux kernel with OMAP3 Camera support option. Now i want to use the camera in my application using V4l2 sample application. I am going to use the camera ISP interface.
 
The Sensor configuration is,
 
        The camera sensor (Sony ICX659ALA) is connected to the AFE (Analog Front End) chip. We are using FPGA for generating the HSYNC, VSYC and PXL_CLK for getting the inputs from image sensor. The FPGA is continuously reading the frames from the sensor after power-on the unit. The captured analog signals are converted to Digital signal by AFE chip. Finally the digital signal is given to the ISP data lines. I don't have any driver interface to control the Image sensor. But the captured raw data is directly given to the ISP data lines[0-11]. Also i have verified the data lines. The digital data is coming from the AFE chip. 
 
CCDC Register Configuration is,
 
ISP CTRL : 0x20210350
ISPCCDC_SYN_MODE : 0x204a0
ISPCCDC_COLPTN : 0x0
ISPCCDC_BLKCMP : 0x0
ISPCCDC_FPC : 0x0
ISPCCDC_FMTCFG : 0x4000
ISPCCDC_LSC_CONFIG : 0x6600
ISPCCDC_CLAMP : 0x10
ISPCCDC_PIX_LINES : 0x0
ISPCCDC_HD_VD_WID : 0x0
ISPCCDC_CFG : 0x0
ISPCCDC_REC656IF : 0x0
ISPCCDC_SDR_ADDR : 0x0
ISPCCDC_HSIZE_OFF : 0x480
ISPCCDC_SDOFST : 0x0
ISPCCDC_FMT_HORZ : 0x0
ISPCCDC_FMT_VERT : 0x0
ISPCCDC_VP_OUT : 0x0
 
 
Now as per camera usage procedure, i have created the pipeline in the following method,
 
root@cm-t3730:/#media-ctl -r -l '"OMAP3 ISP CCDC":1->"OMAP3 ISP CCDC output":0[1]'

root@cm-t3730:/#media-ctl -f '"OMAP3 ISP CCDC":1 [SGRBG10 4096x4096]'
 
 
The path is created successfully. After that i am trying to read the RAW data (12- bit) from the CCDC memory using the capture_mmap application (V4l2 Sample Applications).
 
 
root@cm-t3730:/# ./capturer_mmap
 
But it is giving the following error,
 
 
root@cm-t3730:/# ./capturer_mmap

    Hi Samuthira,

    I'll try to search for the reason about this crash. The register's configuration seems correct but you could refer to the TRM of OMAP3530 section - 12.5 Camera ISP Basic Programming Model.

    About the sensor driver - is it some standard camera driver which is tested with other boards or it is custom driver?

    Could you try to start the capturer_mmap application with specified capture device (for example ./capture_mmap -d /dev/video)?

    BR

    Hi Tsvetolin Shulev,

                       Thank you for your reply. I have run the application in the following method,

                       ./capturer_mmap -D /dev/video2

    This also giving the same error. Also i given media-ctrl -p option. This is displaying video2 device for the CCDC memory. Thats why i choose the video2 device for my testing. Kindly give me the idea for that.

    Thanks
