CS-MIPI-IMX307 hardware trigger

[lnlinh]

Hello.

We recently purchased the cs-tx2-xavier-ncam-imx307 set. I want to synchronize it with LiDAR using the Lidar XVS output. Our base board is Jetson AGX Xavier, L4T 35.1.

Is hardware trigger supported on the CS-MIPI-IMX307 module?

What I have tried:

• disable vi timeout
  v4l2-ctl -c vi_time_out_disable=1 -d /dev/video0 (and video1, video2)
• put camera in hardware trigger mode, then push the SW1 button on the ADP-N1-V2.0 board
  ./cs_mipi_i2c.sh -w -f streammode -p1 2 -b 30 (and 31, 32)
  (it doesn't work. Frames are captured even when i didn't push the capture button)
• put camera in sync mode, all slave
  ./cs_mipi_i2c.sh -w -f streammode -p1 1 -p2 1 -b 30
  ./cs_mipi_i2c.sh -w -f streammode -p1 1 -p2 1 -b 31
  ./cs_mipi_i2c.sh -w -f streammode -p1 1 -p2 1 -b 32
  (Also doesn't work. Frames are captured without button push and they are all blue)

Please confirm whether hardware trigger is possible or not. I am open to workaround suggestion if any.

Thank you.

Sorry, CS-MIPI-IMX307 does not support external trigger mode, only free running and sync mode.
