It appears that the camera was successfully probed on i2c-10. Next, you can refer to Part 9 and Part 10 in this link to try capturing images.
You can also try using veye_viewer.

@myzy said in 请教IMX287M驱动移植到RX3588的操作:

如果没有linux驱动的基础的话，不建议做这个工作。有一定的门槛和难度。
你的主板是什么型号的？
需要首先编译你主板的系统，然后在系统中增加我们摄像头模组的驱动，做出新的系统。

@nian 好的

@golden0514 你可以进一步将fps设置小，相应的最大曝光时间也会拉长。

@golden0514 这篇文章没有修改曝光时间的东西吧？ 有设置格式，分辨率，帧率，取图相关的内容。

@golden0514
可以参考这篇文章进行取图。

@golden0514 你的嵌入式平台是什么？

@nian
你说的对，我们现在还没有那么高的ADC精度的产品。
你的使用场景，动态范围很宽？ 用长短曝光时间来辅助解决可否？

@nian
12bit模式，相机是支持的。但是你现在只可以将其保存为文件，并手动转换为可以方便用软件读取的格式。你可以看一下这个文章part7，尤其是part7.5的部分

14bit这个，我们现在相机还不支持。sensor是有的，我们没有做这个格式。

@nian 不客气

@nian

@nian said in 有一些错误 ，大神们 请指教啊raspi5 +imx78:

但是veye_vbyone不能用 是不是可以忽视往下进行？

是的。
请更新一下最新的github上的media_setting_rpi5.sh，应该就可以解决你现在的问题。

@linoooooo
你好，fps参数是可以修改的。但是需要先停止取图。曝光时间是被限制到1/fps的。 你可以先设置合适的fps，然后在范围内进行曝光时间的修改。

在这个脚本中，带星号的命令，都是取图中写保护的。
你也可以参考寄存器清单中的part1.3来理解这个设置规则。

@fumyang 请问您用的是哪个相机模组？

1. The MV-MIPI-GMAX4002M model was missing on this page and has now been added. Both Jetpack 5.1 and 6.2 are supported. However, we currently only provide the 4-lane mode DTB for Orin NX and Orin Nano under JP6.2 mode, as only these two boards have official baseboards that expose the 4-lane interface.
3. You're right. Just place the order using that link. We will ship ADP-MV1-V2.
4. For Jetson Xavier NX, since the official baseboard only exposes 2 lanes, the DTB in our provided driver remains configured for 2-lane mode, which limits the maximum frame rate.
   As for Orin NX, there is no such restriction. You can refer to the 4 How to Use 4-Lane Modesection to enable 4-lane mode.
5. yes.
6. The MV series products feature ISP (Image Signal Processor) capabilities, including typical functions such as auto-exposure, LUT (Look-Up Table), and more.

@israel_bolo Actually, for the development of new projects, I would recommend using the V4L2 mode, which is the material from the link below.

@israel_bolo

May I ask which version of piOS you are currently using? The libdmipicam mode is only suitable for the 32-bit legacy mode of piOS.

@dragos You are welcome.

@dragos
I think the MIPI CSI interface on this board only exposes 2 lanes and uses a 15-pin connector.
Could you check your board to see if that's the case?

@dragos May I ask if the board you're using is an official NVIDIA development board or a compatible third-party board?

@linoooooo 你好，我们的相机内部isp流程是没有整帧缓存的，相机本身引入的delay是毫秒之内。
我觉得你这个延时主要是v4l2取图缓存和显示缓存的缘故。不过说实话SDL库我们不太懂，怎样优化需要您自己研究一下。
至于相机采集后，您这边程序直接导入算法的话，延迟肯定要比这种测量方法小的多。
