      @g-towboat said in Camera sync mode:

      @veye_xumm
      SYNC signal connect:
      J7-3 (GPIO0) to J1-3 (GPIO0),
      J7-2 (GND) to J1-2 (GND)

      Do i need to do the wireing on each camera? or just master camera.

      everyone

      Any other wiring to do?

      no

            @veye_xumm Hi Xumm,

            I use this script to set sync_mode and master slave config:

            #!/bin/bash
            
            SYNC_INIT="sync_init"
            STREAM_MODE="streammode"
            
            echo -e "connected cameras:"
            ls -l /dev/video* 
            
            echo -e "Set camera 0_1 to Master"
            sh ./fpdlink3_i2c_jetson.sh -f $SYNC_INIT -p 0 -p1 0 -b 30
            sh ./cs_mipi_i2c.sh -w -f $STREAM_MODE -p1 1 -p2 0 -b 30 -d 0x3b
            echo -e "Set camera 0_2 to slave"
            sh ./fpdlink3_i2c_jetson.sh -f $SYNC_INIT -p 1 -p1 1 -b 30
            sh ./cs_mipi_i2c.sh -w -f $STREAM_MODE -p1 1 -p2 1 -b 30 -d 0x3c

            sh ./fpdlink3_i2c_jetson.sh -f $SYNC_INIT -p 0 -p1 1 -b 31
            sh ./cs_mipi_i2c.sh -w -f $STREAM_MODE -p1 1 -p2 1 -b 31 -d 0x3b
            echo -e "Set camera 1_2 to slave"
            sh ./fpdlink3_i2c_jetson.sh -f $SYNC_INIT -p 1 -p1 1 -b 31
            sh ./cs_mipi_i2c.sh -w -f $STREAM_MODE -p1 1 -p2 1 -b 31 -d 0x3c
            echo -e "Set camera 2_1 to slave"
            sh ./fpdlink3_i2c_jetson.sh -f $SYNC_INIT -p 0 -p1 1 -b 32
            sh ./cs_mipi_i2c.sh -w -f $STREAM_MODE -p1 1 -p2 1 -b 32 -d 0x3b
            echo -e "Set camera 2_2 to slave"
            sh ./fpdlink3_i2c_jetson.sh -f $SYNC_INIT -p 1 -p1 1 -b 32
            sh ./cs_mipi_i2c.sh -w -f $STREAM_MODE -p1 1 -p2 1 -b 32 -d 0x3c
            echo -e "Set camera 3_1 to slave"
            sh ./fpdlink3_i2c_jetson.sh -f $SYNC_INIT -p 0 -p1 1 -b 33
            sh ./cs_mipi_i2c.sh -w -f $STREAM_MODE -p1 1 -p2 1 -b 33 -d 0x3b
            echo -e "Set camera 3_2 to slave"

            sh ./cs_mipi_i2c.sh -w -f $STREAM_MODE -p1 1 -p2 1 -b 33 -d 0x3c

            w paramsave,all param will write to flash
            

            Looks good for me.

            If i ask the i2c bus which mode is configured, i get this:

            Camera 0_1
            r streammode 0x 1 slave mode is 0
            Camera 0_2
            r streammode 0x 1 slave mode is 1
            Camera 1_1
            r streammode 0x 1 slave mode is 1
            Camera 1_2
            r streammode 0x 1 slave mode is 1
            Camera 2_1
            r streammode 0x 1 slave mode is 1
            Camera 2_2
            r streammode 0x 1 slave mode is 1
            Camera 3_1
            r streammode 0x 1 slave mode is 1
            Camera 3_2
            r streammode 0x 1 slave mode is 1
            

            To grab images i use my v4l2-ctl script:

            #!/bin/bash
            
            cameras=7
            counter=0
            while [ $counter -le $cameras ]
            do
            	echo -e "Camera_"$counter
            	v4l2-ctl --device /dev/video$counter --stream-mmap --stream-to=frame_$counter.raw --stream-count=1
            	convert -size 1920x1080 -depth 16 uyvy:frame_$counter.raw frame_$counter.png
            	((counter++))
            done
            

            Camera 1 images looks good.
            some cameras a purple some are blue!

              which one is purple,which one is blue?
              I think the script is good. It might be wire connection problem.

                  I think your wire connection is ok. Do you install a lens on your camera?
                  I don't understand the purple image.
                  Please post a purple image and a blue image. let me look at it.

                    No special lens on the cameras - just the standard from veye

                      Hi, I think this camera has no lens mounted. Is it true ?

                        A lens is connected on all camera. If i switch back the configuration to "free run" on each camera, all images look normal.

                          Have you checked the firmware version of each camera?
                          http://wiki.veye.cc/index.php/CS-MIPI-IMX307_version_log

                          4b08e003-f808-4082-8df8-27dfc40de1f9-image.png
                          Make sure firmware version is newer than 2.33.

                                I am REALLY REALLY sorry. I uploaded the wrong version fpdlink3_i2c_jetson.sh before.

                                Please download the newest version I upload to github.
                                https://github.com/veyeimaging/nvidia_jetson_veye_bsp/tree/master/i2c_cmd/bin
                                It works fine here.
                                Sorry again.

                                  i have installed the new version. it looks good for now. One question do i need to set the fpdlink-settings after each reboot?

                                    This cmd need to set after each reboot.

                                    ./cs_mipi_i2c.sh -w -f streammode
                                    The camera can save streammode.
