Hi NV Support Team
From Orin deafult pinmux setting: the camera frame sync used TSC_EDGE_OUT2/3/0.
From TRM part VII-Timers: TSC can use PPS or PTP for reference tracking.
My query is that if TSC_EDGE pins are available on Jetson Orin to support tracking PPS or PTP ?
no, getSensorTimestamp() it returns kernel timestamp (i.e. MONOTONIC_RAW) of sensor start-of-frame.
you are also able to fetch start-of-frame and end-of-frame timing via TSC HW timestamp.
it returns the VI HW (SoF/EoF) timestamp based-on tegra wide timestamp system counter (TSC), it’s the timestamp for the sensor (unit in nanoseconds).
for example, Argus::Ext::ISensorTimestampTsc::getSensorSofTimestampTsc.
syncSensor sample is a software approach, it duplicate single capture request to these two camera sensors.
the idea is having implementation of timestamp comparison from user-space to achieve synchronization results.
