V4l2-ctl gives CHANSEL_NOMATCH

jack31 · October 27, 2021, 12:21am

I’m able to load raw data off my sensor using this command:

v4l2-ctl -d /dev/video0 --set-fmt-video=width=2880,height=1860,pixelformat=RG12 --stream-count=1 --stream-mmap --stream-to=csi.raw --verbose

however, when I connect my camera to the second port on my deserializer chip (still same CSI-2 port on Jetson), the following command hangs and never produces a frame:

v4l2-ctl -d /dev/video1 --set-fmt-video=width=2880,height=1860,pixelformat=RG12 --stream-count=1 --stream-mmap --stream-to=csi.raw --verbose

Trace from command above:

How do I interpret these CHANSEL_NOMATCH messages? The embedded linux wiki implies that the 0x6e9 data means CTYPE=LS and DTYPE=0x37 (which my sensor’s datasheets say correspond to optical black)

hello jack31,

may I know what’s your steps, is this an identical camera sensor?
did you just unplug the camera and plug it into 2nd port?

jack31 · October 27, 2021, 4:53pm

Yeah, this is the exact same camera. Just unplugging it from first port on deserializer board and plugging it into second port.

Here’s the dtsi file I’m using to configure the cameras:

hello jack31,

may I know which JetPack release you’re working with?
please refer to the position property description in Sensor Software Driver Programming, you cannot remix the camera position values with a two-camera plus a six-camera system.

if you’re using r32.6.1,
please refer to Multi-camera Jetson Xavier NX configuration, more than 6 cameras - #10 by JerryChang and apply the patch to fix “Invalid sensor placement is set” failure, and also the reference for the property values to configure more than six camera system.
thanks

jack31 · October 28, 2021, 9:00pm

@JerryChang We’re using r32.5.0 currently.

Where are these position values used? Do you think this would cause the second port on the deserializer board to not work properly?

JerryChang · October 29, 2021, 3:02am

hello jack31,

yse, it’s upper layer to read the position property for mapping its sensor placement.
since you’re using r32.5 release, please have a try to use the duplicate position property for some of your cameras,
BTW, there’s known issue on r32.6, use the duplicate position property will failed
for example,
please have a try to configure position="bottomleft"; for your module0 and also module1.

jack31 · October 29, 2021, 8:42pm

@JerryChang even with duplicated position entries, still having error. here’s the edited device tree

hello jack31,

may I know what’s the error logs, did you still have the same CHANSEL_NOMATCH messages?
could you please add set_mode_delay_ms property to configure the wait time for the first frame after capture starts.
you should also check Sensor Software Driver Programming for reference, thanks

What kind of delay would be appropriate here? 50ms?

hello jack31,

you may evaluate your 1st (workable) camera port to understand the loading time from power-init to 1st frame sending to VI engine.
please check the kernel logs to observe the initial time, please have a try to configure that as set_mode_delay_ms.

Resolved, virtual channel id on packets from second sensor were 0, so Jetson thought second camera wasn’t actually writing any packets
