* Please read through "Camera Development" section in https://developer.nvidia.com/embedded/dlc/l4t-documentation-28-1
== FAQ ==
=== Tips for debugging ===
* if you saw below error message
tegra-vi4 15700000.vi: PXL_SOF syncpt timeout! err = -11
* please check below 4 items in your sensor device tree, these should follow the settings in your sensor datasheet
                                mode0 {
                                        cil_settletime = "0";
                                        active_w = "1920";
                                        active_h = "1080";
                                        embedded_metadata_height = "1";
* if you saw below error message
video4linux video0: MW_ACK_DONE syncpoint time out!
* please check below
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
* 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
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

=== Steps to enable more debug messages ===
* To enable trace for more information
echo 1 > /sys/kernel/debug/tracing/tracing_on
echo 30720 > /sys/kernel/debug/tracing/buffer_size_kb
echo 1 > /sys/kernel/debug/tracing/events/tegra_rtcpu/enable
echo 1 > /sys/kernel/debug/tracing/events/freertos/enable
echo 2 > /sys/kernel/debug/camrtc/log-level
echo > /sys/kernel/debug/tracing/trace
cat /sys/kernel/debug/tracing/trace
* To enable logs from user-space for more details
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
