Hi all, First of all, happy new year :). Next, I am trying to use the second CSI on i.MX6 (still based on media tree and Steve's work, "slightly" modified ;-)). I am using the following lines in order to configure my adv7604 correctly, and running it in free run mode in order to get something reliable : DEVICE=4 INPUT=0 SUBDEV=3 v4l2-ctl -d$DEVICE --set-edid=pad=0,edid=hdmi -i$INPUT v4l2-ctl -d$DEVICE --set-fmt-video=width=1280,height=720,pixelformat=YUYV,field=none,bytesperline=2560 v4l2-ctl -d$DEVICE --set-dv-bt-timings index=4 v4l2-dbg -d$DEVICE -c subdev$SUBDEV -s 0x03 0x80 v4l2-dbg -d$DEVICE -c subdev$SUBDEV -s 0x02 0x35
And then, I launch this simple line, which gets stuck : v4l2-ctl -d$DEVICE --stream-mmap --stream-to /data/x.raw --stream-count=1 The exact same sequence on CSI0 is working fine. I added the dynamic debug messages and here is the configuration (from my point of view, it seems to be ok, but I may have miss a bit here or there) : [ 131.963122] mx6-camera-encoder: Direct CSI ->
