I have a Jetson Nano with an IMU and a raspicam v2.1. Both sensors works fine.
Now I am trying to synchronize the IMU data coming from I2C and the raspicam v2.1 frames coming from the CSI port. To do so I need to know at what time each frame of the camera has been recorded (under 2ms accuracy).
Apparently on the Raspberry pi, it is possible to receive the FRAME START and FRAME STOP flags of every camera frame on the GPIO (https://www.raspberrypi.org/forums/viewtopic.php?t=190314).
You can also find some clarification of how this is achieved here: https://www.raspberrypi.org/forums/viewtopic.php?f=43&t=190314&sid=708f5044517f5c9cbe894a7842322e33&start=25#p1386420
Is there a way to achieve that on the Jetson Nano?
