Hello, we’ve recently flashed a brand new Nano Dev Kit (B01) with JetPack 4.6 and configured its CSI ports to support IMX477 via the jetson-io.py. The Raspberry Pi HQ Camera (with the resistor R8 removed) can be found by v4l2-ctl and can also stream using nvarguscamerasrc. BUT it failed streaming …

Yes, I will make it merge for next or future release.

Sorry for the late resposne, we will have the investigation to do the updat soon.

Thanks for the response. I am working with zhuda on this. Here’s some additional information for you: We have actually tried 3 Nano Developer kits, all with JetPack 4.6 installed and on one of them the camera works well with v4l2-ctl, but on the other two we get the errors mentioned by zhuda most …

@ShaneCCC , I see the same results on two of my identical 2GB Nano dev kits with the Arducam IMX477 Mini. With the stock Nvidia drivers, both on the latest L4T, I am only able to get v4l2-ctl working with one of them. I’ve tried both sensor modes (3840x2160 and 1920x1080 that the stock Nvidia driver …

@ShaneCCC , both 3840x2160 and 1920x1080 have the same problem as described above.

As a side note, it would be great to have the full resolution 4032x3040 30fps sensor mode available as it is in the original RidgeRun and current Arducam drivers. This 4:3 aspect ratio is extremely valuable for certain use-cases. Understandably at that throughput, v4l2 may have bandwidth issues tran…

I just try the dual IMX477 connect to Nano and v4l2-ctl have problem on video1 but without problem on video0.

Just wanted to check in on this. I’m still unable to use v4l2-ctl on one of my Jetson Nano’s. @zhuda , are you still having this same issue?

@ShaneCCC : thanks for the test and response. So do you know that root cause it might be and how to fix it? Because for us both ports (video0 and video1) don’t work with streaming. The IO was configured as IMX477 dual. @dustinkerstein : thanks for the cross check. The issue is still valid. We have th…

Sure thing. You may want to untick the “Solution” button as the thread might get locked automatically. And also, just to clarify, on the Nano 2GB Dev Kit, there is only one CSI port - which does’t work with v4l2-ctl on one of my Nanos - but the other Nano 2GB Dev Kit works fine.

What’s about the 3840x2160 this mode?

V4l2-ctl not respecting frame_rate control, unlike Gstreamer on IMX477 + Nano 2GB
