Hi,
In imx8mplus with isi interface, when i capture the raw image using the command :
v4l2-ctl -d 1 -v width=1920,height=1080,pixelformat=GB12 --stream-mmap --stream-count=1 --stream-to=gbrg_test.raw
the first capture was proper, but when i try to capture the again using the same command it is throwing the dphy status error mentioning : STOPSTATEDAT and STOPSTATECLK.
the logs for second capture are as below:

the logs for first capture is exact same except below change:

can anyone help me to resolve this issue.
Thanks and regards,
