UNSOLVED 移植imx462摄像头驱动到rk3588时出现了以下的问题，不知道怎么解决,内核版本是5.10

[aike]

对的，像这样i2c能识别到摄像头型号

上面的代码编译出错，我把这里连接之后在和设备树一起编译内核，再把veyecam2m编译成veyecam2m.ko模块移植进去之后还是有问题
这个是错误截图

[veye_xumm]

@aike 我觉得dts没问题，你可以试试把veyecam2m直接编译到内核里面，而不是独立ko的形式试试。
关于dts的逻辑关系，你可以参考这篇文章。
https://www.cnblogs.com/armsom/articles/17449250.html

[aike]

直接整合到内核之后没有看到update sensor info failed 的报错信息，但是没有看到isp的设备文件和拓扑接口
摄像头拓扑结构图
摄像头拓扑结构图.txt
抓取图片也有问题

[aike]

应该是又更近了一步，现在无论是自己基于v4l2写的程序或者是gstreamer获取信息显示的画面都是绿色的
这是什么情况呢

[veye_xumm]

@aike 首先，我们这个模组是带有isp的，因此在dts中，isp部分都给bypass掉了。
其次，你可以先试试我们wiki上的gstreamer例子，看看能不能预览。

[aike]

我用gitee上面的gstreamer测试工具测试的时候出现了这些问题
同时串口会打印这些

请问这个问题怎么解决

[veye_xumm]

@aike 这个我们在其他的板卡上没有遇到过。你的板子本身没有带gstreamer吗？ 或者问问板卡厂家。

[aike]

板卡是自带gstreamer的，一直在这里卡住了，会不会是摄像头模组硬件的原因呢

[veye_xumm]

@aike 可能性很小。你试试用这个脚本抓一下图：

v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat='NV12' --stream-mmap --stream-count=100 --stream-to=nv12-1920x1080.yuv
