Hi Vikram,

I tried this on my QCM6490 Fairphone 5 smartphone.

Unfortunately I couldn't get e.g. CSID test pattern out of camss. I've
tested this patchset on v6.11.

These commands did work on an older sc7280 camss patchset (which was
never sent to the lists). Can you please take a look?

v4l2-ctl -d /dev/v4l-subdev5 -c test_pattern=1
media-ctl -d /dev/media0 -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
media-ctl -d /dev/media0 -V '"msm_csid0":1[fmt:UYVY8_2X8/1920x1080 field:none],"msm_vfe0_rdi0":0[fmt:UYVY8_2X8/1920x1080 field:none]'
gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=1 ! 'video/x-raw,format=UYVY,width=1920,height=1080' ! jpegenc ! filesink location=image01.jpg

The last command just hangs instead of producing a picture in
image01.jpg. Can you please check if this works for you on your board?

Regards
Luca
