Subject: adv7280: Scrolling images on imx6
Date: Mon, 26 Apr 2021 13:14:46 -0300	[thread overview]
Message-ID: <CAOMZO5CacHaESju9XQU1C7NU41Myk1-2_+7sju1dnCZuqRv98Q@mail.gmail.com> (raw)

Hi Tim,

I am back at trying to get a proper image captured by the ADV7280 on
an imx6dl board connected to the parallel CSI bus.

I tried your patches against 5.4 and 5.12:

https://github.com/Gateworks/linux-imx6/commit/959fbd4
and
https://patchwork.kernel.org/project/linux-media/patch/20190827215539.1286-1-mmichilot@gateworks.com/

,but I am still getting horizontal scrolling images after running:

media-ctl -l "'adv7180 0-0020':0 -> 'ipu1_csi1_mux':4[1]"
media-ctl -l "'ipu1_csi1_mux':5 -> 'ipu1_csi1':0[1]"
media-ctl -l "'ipu1_csi1':1 -> 'ipu1_vdic':0[1]"
media-ctl -l "'ipu1_vdic':2 -> 'ipu1_ic_prp':0[1]"
media-ctl -l "'ipu1_ic_prp':2 -> 'ipu1_ic_prpvf':0[1]"
media-ctl -l "'ipu1_ic_prpvf':1 -> 'ipu1_ic_prpvf capture':0[1]"
media-ctl -V "'adv7180 0-0020':0 [fmt:UYVY2X8/640x480 field:seq-tb]"
media-ctl -V "'ipu1_csi1_mux':5 [fmt:UYVY2X8/640x480]"
media-ctl -V "'ipu1_csi1':1 [fmt:AYUV32/640x480]"
media-ctl -V "'ipu1_vdic':2 [fmt:AYUV32/640x480 field:none]"
media-ctl -V "'ipu1_ic_prp':2 [fmt:AYUV32/640x480 field:none]"
media-ctl -V "'ipu1_ic_prpvf':1 [fmt:AYUV32/640x480 field:none]"
v4l2-ctl -d2 --set-fmt-video=field=none

gst-launch-1.0 v4l2src device=/dev/video2 ! kmssink

Also, I saw your commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.12&id=9483a3f8e1b58ba1d7cd21687d8d0a63a015c36b

,but adv7180_get_skip_frames() does not get called. Is there any
missing patch from the mix csi driver that should call
g_skip_frames()?

Any suggestions?

Thanks,

Fabio Estevam
