UNSOLVED 关于第三方载板移植SC132M时发现只有当两个相机同时接入时才能工作的问题

@robot
这样的话，岂不是没有问题吗？ -
@veye_xumm d但是此时相机读取到的图像是全黑的，正常应该是实际拍到的东西
-
@robot 现象目前有所变化，dmesg打印变成了：

@robot 事实上我现在对设备树进行了修改，去掉了另一路相机只保留了一路，然而他的现象又改变了：

如果方便的话，我是否需要上传我的设备树文件？希望能得到您的帮助 -
@robot 你现在现象是：同时插入两个camera的时候，图像正常。 只使用一个，不能正常使用。是这样吗？

设备树文件要跟你的硬件载板想匹配。 具体来说，对每一个MIPI CSI-2接口，其i2c bus和mipi总线的配置，要匹配。

@veye_xumm 是的，就是这个意思

按照原理图来看是匹配的，我来对调mipi总线测试一下

@robot
有一种可能，你的i2c和mipi是错配的。
