imx8mp mipi csi capture with 4 mipi lines issue

[jignesh1]

We are using mipi csi one interface with 4 mipi lines are connected. I used to received 1280x720 preview data at 60 fps.. application running fine to capture video frame but after some time observing "mxc-mipi-csi2.0: FIFO Overflow Error"  and due to this we observed csi interrupt increase rapidly and hanging imx8mp board.

 lt7911d_out: endpoint {

                                remote-endpoint = <&mipi_csi0_ep>;

                                data-lanes = <1 2 3 4>;

                                clock-lanes = <0>;

};

To simulate issue, I use following command to capture video: v4l2-ctl -d /dev/video3 --stream-mmap --stream-count=66 --verbose 

Also with this application I have attached log to show fifo error during capture.. Do we have any hint about where can be the issue.

Thanks,

Jignesh

what hssettle did you set? and what mipi clock do you measure?
