SOLVED Camera sync mode
-
@veye_xumm
i'm sorry, but i still haven't got it. Can you describe it in a table e.g.:
J6 Pin X - J8 Pin YThank you
-
It's not some pairs of connection. It's a group of connection.
For example:
J6-2 is the source of XVS, and J6-4 J6-6 J6-8 J8-2 J8-4 J8-6 J8-8 are all sink of XVS.
So what you need to do is connect all these pins together.J6-1 J6-3 J6-5 J6-7 are already connected together on the board.
J8-1 J8-3 J8-5 J8-7 are already connected together on the board.
You can use them if you want.

e.g my post here:
http://forum.veye.cc/topic/21/camera-i2c-configuaration-for-sync-modeI just have blue images like the post here:
http://forum.veye.cc/topic/22/i-want-to-synchronize-the-two-cameras-in-sync-mode
But i have 8 cameras connected.Do I also connect the boards: FPD-LINK3-2RX?
or is it the i2c configuration? -
@g-towboat
Since you use CS-FPD-XAVIER-nCAM-IMX307, FPD-LINK3-2RX is a part of this module. -
@g-towboat
You can post your hardware connection here, I'll check it for you. -
I think it's worked now, i have made an Firmware update of each camera. What is the best way to check synchronization?

@veye_xumm I still have blue Images.
Wire configuration standard.
Changed as reference in http://forum.veye.cc/topic/22/i-want-to-synchronize-the-two-cameras-in-sync-mode/6?_=1616485571342
Can you please check what i am doing wrong or post a detailed photo of the right configuration.
Thank you -
@g-towboat
I think you pick out the wrong wire. -
@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.
Any other wiring to do? -

everyone

no

@veye_xumm
It just work with two cameras but not with 8.
Any other ideas whats wrong ? -

pls check you setting following :http://wiki.veye.cc/index.php/FPD_LINK_III_for_Jetson -
@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 0x3cThis is the result:

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 1To 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++)) doneCamera 1 images looks good.
some cameras a purple some are blue!
Do you need more informations? Or do you have any ideas whats wrong?

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. -
@veye_xumm
Hi here is my drawing:
Red: the jumpers
Green: the two black delivered wiresFollowing cameras showing this kind of image:
Camera 1 /dev/video0 image ok
Camera 2 /dev/video1 blue image
Camera 3 /dev/video2 purple image
Camera 4 /dev/video3 image ok
Camera 5 /dev/video4 purple image
Camera 6 /dev/video5 blue image
Camera 7 /dev/video6 purple image
Camera 8 /dev/video7 blue image -
@g-towboat
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. -
@veye_xumm
No special lens on the cameras - just the standard from veye
Here is an image
-
@g-towboat
Hi, I think this camera has no lens mounted. Is it true ?
