Second imx477 camera doesn't work

[waldemar.friesen]

I have made followed changes in file tegra210-p3448-0002-p3449-0000-b00.dts:

#include "tegra210-porg-p3448-common.dtsi"
#include "porg-platforms/tegra210-porg-camera-rbpcv3-dual-imx477.dtsi"
//#include "porg-platforms/tegra210-porg-camera-rbpcv2-dual-imx219.dtsi"
#include "porg-platforms/tegra210-porg-pinmux-p3448-0002-b00.dtsi"
#include "porg-platforms/tegra210-porg-gpio-p3448-0002-b00.dtsi"
#include "porg-platforms/tegra210-porg-p3448-emc-a00.dtsi"

and then one camera is working. with second cam is there problem too, when the binary from arducam will apply.

Does the video node created? (/dev/video1)

[waldemar.friesen]

hello @ShaneCCC,
yes it is there together with video0

[ShaneCCC]

Did you check with v4l2-ctl if able capture successfully.

[waldemar.friesen]

I checked it with gst-launch-1.0 and python script from the Github-Repository JetsonHacksNano.

[ShaneCCC]

Please run the v4l2-ctl to make sure the HW and driver without problem.

[waldemar.friesen]

could you give me a command with this I should do that? I have had problems with this one:

v4l2-ctl --device /dev/video1 --set-fmt-video=width=1920,height=1080,pixelformat=MJPEG --stream-mmap --stream-to=frame.jpg --stream-count=1

[ShaneCCC]

Try below

v4l2-ctl --device /dev/video1 --set-fmt-video=width=1920,height=1080 --stream-mmap -c bypass_mode=0

[waldemar.friesen]

after installing the packet with sudo apt install v4l-utils. I have the output:

wlad@ubuntu:/media/wlad/Copy/CAM$ v4l2-ctl --device /dev/video0 --set-fmt-video=width=1920,height=1080 --stream-mmap -c bypass_mode=0

last command remain ca. 5 minutes in this state before cancelled.

Looks like the script start two cameras simultaneity.
Do you try below command to launch second camera?

gst-launch-1.0 nvarguscamerasrc sensor-id=1 ! "video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080,format=(string)NV12, framerate=(fraction)30/1" ! nvvidconv ! xvimagesink sync=false

[waldemar.friesen]

yes it is tried with non working camera result. What could it be?

[ShaneCCC]

Do you mean above command working for non working camera??

[waldemar.friesen]

only for one camera, it is working.

[ShaneCCC]

OK, didn’t switch the camera port to check if any HW problem cause the issue?

[waldemar.friesen]

yes I have 4 ports all are checked for function. These are the connections between Jetson nano module and camera:

The AB-Channel is working. Should maybe A and B be different cameras on board?

[waldemar.friesen]

Hello Shane,
how can I change the number of csi_lines?
I have set already in tegra210-camera-rbpcv3-dual-imx477.dtsi and have had no success with that:

num_lanes = "4";
port-index = <0>;
bus-width = <4>;
port-index = <2>;
bus-width = <4>;
num_csi_lanes = <8>;

[ShaneCCC]

It could be include the tegra210-camera-rbpcv3-imx477.dtsi that override it.
Check and remove it to try.
