STOPSTATEDAT: error for 2nd capture in imx8mp in ISI interface.

[mukesh_kumar]

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,

Hi,

Im facing the same problem with CSIS_DPHYSTATUS when i trying to capture RAW10 with ov5640 or imx290. The first capture is fine, but the second one (third, fourth...) are blocked.  The only way to capture data again is reboot system or reboot camera, CSI and IMX8_media_dev driver modules.

Hi @mukesh_kumar ,

I was having this issue with kernel 5.10.35 with kernel 5.10.52, this problem is gone
