How to restore my CSI camera setting in my Jetson?

Robotics & Edge Computing Jetson Systems Jetson Xavier NX

HI, my Jetson worked fine before with my small csi camera. Then, I bought a new IMX477 camera and followed this video and did the installation for the IMX477 camera driver.

The IMX477 camera works, but as the IMX477 is connected to CSI 1 slot in hardware, the software sees it as CSI 0. It is strange….

Now, my original csi camera setting got mess up, the csi:0 does not connect anymore even after I removed the IMX477 from CSI 1 slot.
Error generated. /dvs/git/dirty/git-master_linux/multimedia/nvgstreamer/gst-nvarguscamera/gstnarguscamerasrc.cpp, execute:725 No cameras available

How can I set my original CSI camera back to normal? Thx

May I know which Jetson platform and JetPack SW you’re using?

My NX is really old, jetpack is 4.6-b199

Here is the update. Either I put the IMX477 in csi 0 or 1 in hardware, the software sees the IMX477 at csi:0

When I plug in another old csi camera, the NX cannot find it.

When I plug my USB camera in, the USB becomes /dev/video1. And when I use dustynv inference, the USB camera can not provide frame….. But the Cheese can…. Not sure why….

As the IMX477 driver mess up the camera setting, I just want to restore it back. Thx

Please use jetson-io to enable dual imx477 to verify.

sudo /opt/nvidia/jetson-io/jetson-io.py ? disable the IMX477?

Enable dual IMX477

Does not work. Same as before. I have save the pin and reboot….

For the USB camera, it is /dev/video0 now. I can still use Cheese to see the USB camera. However, when I try to run dusty nv inference using /dev/video0,

Capture() – a timeout occurred waiting for the next image buffer.

Same code and it works for the IMX477. (Not other typical CSI camera though, it worked before I installed that IMX477 driver)…. :< thx

Your IMX477 is from ArduCam?

BTW, the USB camera functionality shouldn’t matter with CSI camera but only the video node will shift if CSI camera probe successfully.

12

Yes IMX477 from ArduCam, the IMX477 works fine. But its driver mess up other cameras, including the USB camera. One hint is that before the setting you gave me, the IMX477 occupy the /dev/video0.

My plan B is to flash the NX again but the SDK manager disable the NX. :< Where can I download the Jetson 4.6 (work for dusty nv inference) image? Thx

Check below link

If I don’t pick the dual IMX477, I pick “Camera IMX477-A and IMX219-B, the original CSI camera works. But the IMX477 does not work anymore even after I select the Dual IMX477…. The IMX477 is in CSI 0

What is the reason I wonder….

15

What’s your original camera?

You need to confirm by “sudo dmesg | grep -i imx” to know each sensor loaded.

16

Just a typical CSI camera, just like Rpi v2.1 camera. How can I list all CSI camera that is connected? Thx I still cannot get the IMX477 working anymore….

You should able check by v4l2-ctl –list command.
