Hi Steve,
Are you still able to capture from the camera on the imx53-smd board
with kernel 5.3.x?
I haven't tried the SMD board in a while, it's possible something broke,
but see below...
I have a custom board with a ADV7180 and it gets detected like this:
[ 2.970246] ipu1_csi0: Registered ipu1_csi0 capture as /dev/video0
[ 2.979741] ipu1_ic_prpenc: Registered ipu1_ic_prpenc capture as /dev/video1
[ 2.988930] ipu1_ic_prpvf: Registered ipu1_ic_prpvf capture as /dev/video2

[ 3.009925] imx-media: ipu1_csi0:1 -> ipu1_vdic:0
[ 3.014659] imx-media: ipu1_vdic:2 -> ipu1_ic_prp:0
[ 3.019929] imx-media: ipu1_ic_prp:1 -> ipu1_ic_prpenc:0
[ 3.025305] imx-media: ipu1_ic_prp:2 -> ipu1_ic_prpvf:0
[ 3.032039] mmc0: new high speed SDHC card at address aaaa

[ 24.974982] adv7180 1-0021: chip found @ 0x21 (63fc4000.i2c)
[ 25.324516] imx-media: adv7180 1-0021:0 -> ipu1_csi0:0
Then I setup the pipelines:
# media-ctl -l "'adv7180 1-0021':0 -> 'ipu1_csi0':[1]"
# media-ctl -l "'ipu1_csi0':2 -> 'ipu1_csi0 capture':0[1]"
# media-ctl -V "'adv7180 1-0021':0 [fmt:UYVY2X8/720x480 field:seq-bt]"
The adv7180 driver in 5.3.x doesn't support seq-bt, only alternate. So
pad format should be "[fmt:UYVY2X8/720x240 field:alternate]".
# media-ctl -V "'ipu1_csi0':2 [fmt:AYUV32/720x480]"
# gst-launch-1.0 v4l2src ! fakesink
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...

New clock: GstSystemClock
[ 929.317827] ipu1_csi0: pipeline start failed with -32
This probably means there was a pad format mismatch. Try enabling
dynamic debug.

My device tree changes to add the ADV7180 are listed here:

Am I calling the correct media-ctl commands?
Any ideas, please?
Thanks,
