The boards I use are jetson tx2 nx core board and custom carrier board. I refer url link Device Tree for CSI MIPI to modify the device tree file and enable the lt6911 driver. I connect my windows PC HDMI ouput to my jetson tx2 nx board HDMI input, but I cannot capture the video streaming using the v4l2 tools.
The ouputs are given as follows:
~$dmesg |grep lt6911
