@nb 不客气。

@veye_xumm 好的，感谢

@antony
You've made a very accurate analysis and testing, which is admirable.
For this camera model, to save space, we use a double-sided contact connector, which indeed has caused some issues. We are planning to improve this module by replacing it with a 22-pin single-sided contact connector.

I, together with our hardware colleagues, conducted an analysis, and the results align with your test findings.
After reconnecting the FFC cable correctly following a reversal, the sensor's registers and error codes did not indicate a damaged state for the camera.

In the case of reversed power connection, the pins that are actually damaged are CON_CS_D1P and CON_CSI_CLKP. Unfortunately, this issue cannot be detected through software.

@lakers said in orin nano4g板卡使用MV-MIPI-IMX264M的问题:

我用您提供的sample中的 show.grey.py文件可以看见图像但帧率极低，用qv4l2却看不到图像，显示一片黑

python这个demo是帧率很低的。因为是纯软件跑到cpu上作的数据搬移。你回头开发自己的程序的时候，可以避免这一点。

qv4l2这个可能是因为分辨率太高了，qv4l2这个软件的兼容性的问题。

整体来看，我觉得驱动已经通了，你可以跑跑我们wiki上其他的例子了。

@robot
有一种可能，你的i2c和mipi是错配的。

@robot 不客气。

@xym 好的。

@veye_xumm 能否提供一些在python或是c/c++中可用的读取接口或程序示例，我需要一个确定可用的程序对摄像头进行功能测试，最好能兼容opencv和gstreamer
