Not detecting the ov13850 camera module in CCI1 line

ann · September 22, 2020, 11:40am

Hi,

I am using the kernel version 4.14 and sd820c board.
Trying to use the CCI-I2C1 bus for the secondary camera.
While doing the modeprobe, am getting the following logs. The sensor ID is always showing as 0x000.

Could anyone please help me on the same.

Hi Loic,

I am able to detect the ov13850 camera in the CCI-I2C1 bus for the secondary camera.

I was able to configure the secondary camera using the following commands:-

media-ctl -d /dev/media0 -l ‘“msm_csiphy1”:1->“msm_csid1”:0[1],“msm_csid1”:1->“msm_ispif1”:0[1],“msm_ispif1”:1->“msm_vfe0_rdi1”:0[1]’;sudo media-ctl -d /dev/media0 -V ‘“ov13850 4-0010”:0[fmt:SBGGR10_1X10/2112x1568 field:none],“msm_csiphy1”:0[fmt:SBGGR10_1X10/2112x1568 field:non’

But am not able to capture the image.

I used the following yavta command for capturing the image:-
yavta -B capture-mplane -c1 -I -n 1 -f SBGGR10P -s 2112x1568 /dev/video1 -F

The command is halt by giving the following logs:-

Device /dev/video1 opened.
Device Qualcomm Camera Subsystem' on platform:a34000.camss’ (driver ‘qcom-camss’) supports video, capture, with mplanes.
Video format set: SBGGR10P (41414270) 2112x1568 field none, 1 planes:
