Imx6Q cant get camera input

[shlomiperlman]

Hi,

I have set up my camera sensor and i can see the rgb data lines (on the scop) after the driver had finished initialing the device

but i cant get the data from any /dev/video* and mxc_v4l2_capture gives:

mxc_v4l_open: Mxc Camera no sensor ipu1/csi1

mxc_v4l_open: Mxc Camera no sensor ipu0/csi0

mxc_v4l_open: Mxc Camera no sensor ipu1/csi0

mxc_v4l_open: Mxc Camera no sensor ipu0/csi0

my device in the DTB is set to

ipu_id =<0>

csi_id =<0>

and the data pins are the sames as the control pins for the ov5642.

thanks,

[daiane_angolini]

Please, share the kernel log for camera driver probe, and how are you trying to get data from camera (is it a gstreamer cmd line? or a unit-test? or a cat?)

[shlomiperlman]

hi,

have you looked on the new info i sent?

[daiane_angolini]

Yes, I saw, and I was not able to find anything to stop from your log, everything looks normal. I would review HW + dts

And maybe other with more IPU expertise can help you better

[shlomiperlman]

Hi,

how can i send you the dts files? the comment window doesnt have an attachment option.

any thing else i can check or do on my part?

thanks,

[daiane_angolini]

you can use the 'advanced' editor to find an 'attach' button

[shlomiperlman]

thanks, i attached the dts files.

please note its configured for gc0309.

Hi,

I tried cat and gstream, both give the same result.
