We found a way let argus satisfy.
Change the resolution to 1920 1080 in dts , and with certain line length, “gst-launch arguscamerasrc ! fakesink” not going die now, Although sensor register setting to 3840 2160.
And I found this post https://forums.developer.nvidia.com/t/arducam-imx-219-not-giving-4k-video/201367/42
Is there some relations between the post and my problem?
I’m really appreciate for your help!
