I flashed the kit with JetPack using SDK Manager. Weird thing: when I flashed 4.6.1 I could actually see /dev/video0 and /dev/video1, but after flashing 4.6 the devices just don’t appear at all. Nothing in /dev/video*.
The cameras I’m trying:
Arducam MINI IMX219 camera module for Jetson Nano/Xavier NX (SKU: B0342)
Arducam IMX219 Low Distortion IR Sensitive (NoIR) M12 Mount Camera Module for NVIDIA Jetson Nano (SKU: B0187)
I already got a reply from Waveshare and they say it should work. Is there some workaround from the Arducam side? Anyone seen this 4.6 vs 4.6.1 difference?
A quick clarification first: there’s no real difference between our IMX219 and the official IMX219 module. Our main advantage is that the lens is replaceable, so we can treat your question essentially as if it were the official IMX219.
One important caveat: we don’t work with Microsnow, and all of our testing is done on the official Jetson development board. So for third-party hardware we can’t give a 100% guaranteed solution - but we can still help.
The fact that 4.6.1 shows /dev/video0 and /dev/video1 while 4.6 shows nothing is a useful clue. To diagnose it, can you send us the dmesg output from the device? We can look at the errors there and narrow it down even on the official dev board.
Please show the dmesg information on the device and paste it here.
Sorry for the slow reply, I’m still looking into this for you.
Before we go further I need the diagnostic data. Please generate an Arducam bug report - this collects the system and camera info we need to figure out why the camera isn’t being detected.
This will output an arducam-bug-report.txt in the current directory. Please send that file as an attachment here. Also, if you can, send a new picture/diagram of the hardware connection - it helps us see how the CSI cables are routed.
If you already ran it, just attach the file again so I’m sure I have the latest one.
Ah, I think there’s a mix-up. The camera you saw detected is a USB camera (UB020201) that I also had connected to the Nano - that’s not the one I’m trying to get working. Sorry, should have mentioned that.
I’ve now removed the USB camera. Please see the attached screenshot for the output of:
v4l2-ctl --list-formats-ext
Also please check the latest report file I attached earlier - that should reflect the current setup.
Looking at what you sent, I have to be honest - I’ve never seen a CSI interface like the one in your setup, and the fact that the camera gets tested 4 times isn’t normal. On the official Jetson Nano development kit the CSI is usually buses 7 and 8 (<-> i2c buses).
So a couple of questions:
Is the system you installed actually the official one?
If possible, do you have an official IMX219 camera you could test with, just to see if it works? That would help us isolate whether it’s the module or the platform.
Looking at everything so far, there’s something weird going on with your system - I’ve attached an image pointing at the part that looks off (it’s around the repeated camera-enable behavior).
If you’re sure both the device and the system are official, then this is really something to check with the official (NVIDIA) source. I’m happy to ask them on your behalf if you confirm the device and system are official.
Note the thread title references the camera being enabled four times - that matches the abnormal repeated camera-enable behavior we saw earlier. Please post your setup details and the report there.
I replied in the NVIDIA forum. Here’s what I posted:
“That’s not actually 4-times to enable the same camera, it’s looking for imx219 at four different i2c buses but all return with probing failure. May I know what camera module you’re using?”
I read your reply in the forum thread - nice description of the probing behavior, that helps a lot. I’ll keep an eye on it daily and follow up there.
In the meantime, can you send me a couple more outputs? Please reboot your device first and then run the commands below, because after prolonged use dmesg gets very messy and hard to read:
dpkg --list
dmesg
Attach both outputs here. And can you confirm again whether your system was installed by official means? Just want to be sure before I dig further.
By “official” I mean your system’s device tree - the directory it’s currently using isn’t the official one. SDK Manager can also install third-party/custom system images, so flashing through SDK Manager doesn’t by itself guarantee it’s an official build. I’ve attached screenshots showing the device tree / system part that looks non-standard.
So the recommended path here: burn an official Jetson system image and test the camera on that. That will rule out a non-official system as the cause of the CSI detection and i2c probing failures.
Summary of where we are:
Camera/module itself is being detected, but your CSI interface (4x bus probing failures) and device tree don’t match the official Nano configuration (official CSI is usually buses 7 and 8).
USB camera UB020201 detects fine, so this is specific to the CSI IMX219 path.
The repeated camera-enable behavior has been escalated to NVIDIA’s developer forum.
Next action on your side: flash an official Jetson image and test again; if it still fails on a confirmed official system, we’ll continue from the forum thread with NVIDIA. Send me the results once you’ve tried the official image.
