@sanlu
This is indeed a bug, please refer to this link below to upgrade the camera firmware to version MV-MIPI-IMX178M_C1.44_L2.01_upgrade_20241121.bin.

@victor Sorry for the late reply.
After communicating with the sensor manufacturer, I found that the built-in temperature sensor in the SC130GS is extremely inaccurate and cannot be used properly.

@zang 相机是支持这个分辨率配置的。你的整个操作报什么错误吗？
可以用mv_mipi_i2c.sh脚本读取一下相机实际roi确认是否已经配置到camera里面。
另外300不利于对齐，你可以试试304

@alex_ai said in IMX462M pixelformat on RPi5:

I need wait for clear sky to test and provide feedback

Finally tested, for gain value 20 it is looks pretty same with color sensor with ISP, but background no so black as for color sensor.
For me this issue resolved, attached examples to compare (10 seconds stacks)

@nb 您好，我遇到了类似的问题，请问一下您的解决方案就是将4.6的opencv更换成4.2的opencv吗？

@xym 可能是pipeline效率的原因，buffer不够用导致丢帧了。

@roman I'm sorry, we do not have that plan at the moment.

@veye_xumm Thanks, this should be enough I think

@veye_xumm 好的 感谢

@张志伟 不好意思，我们现在相机本身没有图像矫正功能，也没有使用板块的ISP模块的方案。

@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。
