Our development board is freescale's SABRE Automotive Infotainment  IMX6DL,BSP is L3.0.35_4.1.0_130816_source,our video device is  ADV7180.

 

 

 

      I config the ADV7180 driver in the linux kernel menu config as follow:    

    

      device drivers > Multimedia support > video capture adapters > [M]MXC  Camera/V4L2 PRP Features support > [M] Analog Device adv7180 TV Decoder Input support

 

     The kernel was build success . I copy the \linux-3.0.35\drivers\media\video\mxc\capture\*.ko files to the development board,and use the follow cmd to add adv7180 driver,success too:

     insmod adv7180_tvin.ko
     insmod camera_sensor_clock.ko
     insmod ipu_bg_overlay_sdc.ko
     insmod ipu_csi_enc.ko
     insmod ipu_fg_overlay_sdc.ko
     insmod ipu_prp_enc.ko
     insmod ipu_still.ko
     insmod mxc_v4l2_capture.ko

 

 

     use the follow cmd find have six video device files in the /dev/ dir.

    
root@freescale /unit_tests$ ls /dev/ | grep video
video
video0
video1
video16
video17
video2

 

 

    root@freescale /testTmp$ lsmod
Module                  Size  Used by
mxc_v4l2_capture       22741  1
ipu_still               1703  1 mxc_v4l2_capture
ipu_prp_enc             4685  1 mxc_v4l2_capture
ipu_fg_overlay_sdc      4868  1 mxc_v4l2_capture
ipu_csi_enc             2937  1 mxc_v4l2_capture
ipu_bg_overlay_sdc      3925  1 mxc_v4l2_capture
camera_sensor_clock      765  0
adv7180_tvin            7527  0

 

 

 

         then i go to the /unit_tests dir, use the follow cmd to test the camera:

 

./mxc_v4l2_tvin.out -ow 640 -oh 480 -ol 10 -ot 20 -f YU12     

 

         the output is follow :
           
VIDIOC_DBG_G_CHIP_IDENT failed.
Setup v4l capture failed.

 

 


         i aloso use the follow cmd to test the camera:

 


./mxc_v4l2_capture.out -iw 1280 -ih 720 -ow 1280 -oh 720 -r 0 -fr 15 test.yuv

 

 

 

in_width = 1280, in_height = 720
out_width = 1280, out_height = 720
top = 0, left = 0
VIDIOC_DBG_G_CHIP_IDENT failed.
get format failed

 

 

 

 

 

 

 

       other tests is failed also:

 

 

 

 

 

root@freescale /unit_tests$ $modprobe mxc_v4l2_capture
-sh: mxc_v4l2_capture: command not found

 

 

 

 

 

 

 

root@freescale /unit_tests$ gst-launch tvsrc ! mfw_v4lsink

        Now ,my question as follow:

 

 

 

     1)  My adv7180 video camera driver is config correct? How do i config the adv7180 video camera driver

 

 

 

     2)  Which program in the  /unit_tests dir should i use to test the camera?
