Tips for debugging
TX1 tegra-vi4 15700000.vi: PXL_SOF syncpt timeout! err = -11
 * if you saw below error message

mode0 { cil_settletime = "0"; active_w = "1920"; active_h = "1080"; embedded_metadata_height = "1";
 * please check below 4 items in your sensor device tree, these should follow the settings in your sensor datasheet

video4linux video0: MW_ACK_DONE syncpoint time out!
 * if you saw below error message

sudo su cd /sys/kernel/debug/dynamic_debug/ echo file csi2_fops.c +p > control
 * Enable the csi debug message from below command, and use v4l2-ctl to verify the driver first.

v4l2-ctl -d /dev/video0 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=3

please review the configuration of "line_length" in sensor driver try to increase the delay between video lines data send via CSI review the sensor datasheet to check the settings of FPS range
 * please check below

TX2 arm-smmu 12000000.iommu: Unhandled context fault: iova=0x00000000, fsynr=0x200011, cb=19, sid=4(0x4 - VI), pgd=0, pud=0, pmd=0, pte=0
 * if you saw below message it could be the sensor output embedded data line but DT didn't declare embedded_metadata_height or it value is 0

Steps to enable more debug messages
sudo su kill the process of argus_daemon or nvcamera-daemon export enableCamPclLogs=5 export enableCamScfLogs=5 /usr/sbin/argus_daemon     option for argus /usr/sbin/nvcamera-daemon  option for gst-launch launch camera from another console
