Hi,
has anyone ever get into an incomplete MJPG frame error streaming a UVC camera connected on RK3288 host#1 (dw)? connecting the same camera on host#0 (ehci) it work without any error. This happens only with format equal or grater than 1920x1080 so I suppose could be a bug in dwc2 kernel driver. Is it possible?

I check it using a command like

v4l2-ctl --verbose -d /dev/video2 --stream-mmap=2 --stream-to=./stream.jpg --stream-count=10 --stream-poll

I do not see any error on dmseg log but I obtain partial MJPG frames.
thank you
Andrea
