Jetson orin nx

你好,我在jetson orin nx上使用IMX477 csi接口摄像头,根据IMX477芯片参数,应该是有多种分辨率以及帧数可以选择的,但是为什么我在jetson上使用v4l2-ctl --device=/dev/video --list-formats-ext只显示了两种分辨率,这与IMX477的参数完全不一样,这是为什么呢,跟相机驱动有关系吗?

It must be the driver and device tree problem.
Do you use default driver that enable by jetson-io?
What’s the BSP version? (cat /etc/nv_tegra_release)

是的,我使用的是/opt/nvidia/jetson-io中的程序,BSP version:# R35 (release), REVISION: 4.1, GCID: 33958178, BOARD: t186ref, EABI: aarch64, DATE: Tue Aug 1 19:57:35 UTC 2023

Just check the default driver only implement these two sensor modes.

Thanks

那如果我要完全使用到摄像头的各个参数,应该怎么实现呢

You need add new sensor mode REG table and report different size in device tree for it.

Thanks

是指修改/opt/nvidia/jetson-io中的程序吗,请问你可以讲的详细一点吗,谢谢!

Can’t do it via jetson-io. Need sensor driver and device tree to add new sensor mode.

Please check below for the driver and device tree implementation.
