Hi All,

I'm trying to verify MIPI-CSI2 OV5640 camera on i.MX6 platform with
Mainline Linux.
Sorry to resurect this, but before diving deep into details, do anyone
of you verified JPEG capture with ov5640 and i.MX6 platforms, and has
maybe a pipeline configuration to share :) ?

I have a 4.14 kernel for my i.MX6D/Q using an ov5640 connected in a
similar way as the sabresd and I'm getting similar timeouts.
when executing

media-ctl -l "'ov5640 2-0010':0 -> 'imx6-mipi-csi2':0[1]"
media-ctl -l "'imx6-mipi-csi2':2 -> 'ipu1_csi1':0[1]"


You're routing through imx6-mipi-csi2 pad 2, which is CSI-2 virtual
channel 1, so make sure the ov5640 is transmitting on that channel,
see virtual_channel module parameter.


media-ctl -l "'ipu1_csi1':1 -> 'ipu1_ic_prp':0[1]"
media-ctl -l "'ipu1_ic_prp':1 -> 'ipu1_ic_prpenc':0[1]"
media-ctl -l "'ipu1_ic_prpenc':1 -> 'ipu1_ic_prpenc capture':0[1]"


media-ctl -V "'ov5640 2-0010':0 [fmt:UYVY2X8/640x480 field:none]"
media-ctl -V "'imx6-mipi-csi2':2 [fmt:UYVY2X8/640x480 field:none]"
media-ctl -V "'ipu1_csi1':1 [fmt:AYUV32/640x480 field:none]"
media-ctl -V "'ipu1_ic_prp':1 [fmt:AYUV32/640x480 field:none]"
media-ctl -V "'ipu1_ic_prpenc':1 [fmt:AYUV32/640x480 field:none]"

[ 72.799015] ipu1_ic_prpenc: EOF timeout
[ 73.838985] ipu1_ic_prpenc: wait last EOF timeout

When I try to jump directly to 4.19-RC8, I get errors regarding memory
allocation, so I think there might be something else there I am
missing.

Has anyone tried this camera module on a 4.14 kernel? I noticed there
are a bunch of driver updates, and I was hoping there might be some
patches that could be be backported to the 4.14.y stable branch.

I would suggest backporting all the ov5640 commits. You can also
backport the imx-media commits, but that shouldn't be the cause
of the timeouts you are seeing.

thanks for any suggestions to try.

adam

Thanks

I've followed these[1] instructions to configure MC links and pads
based on the probing details from dmesg and trying to capture
ipu1_ic_prpenc capture (/dev/video1) but it's not working.

Can anyone help me to verify whether I configured all the details
properly if not please suggest.

I'm pasting full log here, so-that anyone can comment in line and dt
changes are at [2]
