      I think you pick out the wrong wire.

        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.
        Any other wiring to do?

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

                This is the result:

                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.

                  Could you draw a sketch of this part? let me have a look.

                      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
                        Here is an image

                          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.

                                    It works fine here.

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

                                        It is really nice.

                                        @g-towboat said in Camera sync mode:

                                        One question do i need to set the fpdlink-settings after each reboot?

                                        ./fpdlink3_i2c_jetson.sh -f sync_init .....
                                        This cmd need to set after each reboot.

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