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

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。

按照原理图来看是匹配的，我来对调mipi总线测试一下

@veye_xumm 是的，就是这个意思

@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：

@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

@veye_xumm said in 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:

如果检测不到，用

可以检测到相机，在/dev下有video0显示

rt，我们的载板使用的csi通道为2，3和标准开发板不同(0,2)，因此在使用RAW_MIPI_SC132M时，我们对设备树进行了修改，修改后成功的到了两个相机的图像
但是最近偶然发现当拔掉其中一只相机后，另一只也不能出图了，看了一下dmesg，有报错，打印如下：
[ 49.719292] tegra-vi4 15700000.vi: PXL_SOF syncpt timeout! err = -11
[ 49.727284] tegra-vi4 15700000.vi: tegra_channel_error_recovery: attempting to reset the capture channel

[ 49.749641] nvcsi 150c0000.nvcsi: csi4_stream_check_status (2) ERROR_STATUS2VI_VC0 = 0x0000000c
在对照了半天标准设备树后未果，因此想请教一下，这可能是由什么原因导致的？

@veye_xumm 是的，确实是未装镜头导致的，实际图像正常，感谢您的指点

我们正在计划在自行研发的Tx2Nx控制器上面使用RAW_MIPI_SC132M这个模块，目前在调试阶段已经调到可以出图了，但是出图不对，看图像数据也都是00和FF，不像是正常图像
这个是我们用v4l2命令导出后用vooya打开的图像，我们不太清楚是哪里的问题，想得到您的指点

@veye_xumm said in Jeston Tx2 Nx + cs132 v4l2获取图像，一段时间后显示VIDIOC_DQBUF failed!Input/output error:

@robot 请问摄像机采用的什么工作模式？
另外请检查一下ffc排线是否插牢，左右对称。

手动曝光模式，1280*720P的模式下,另外我使用的是CS-FPD-CAM-SC132，且链接了两路，其他没有什么特殊的。
就是正常在抓流，代码也是根据教程来写的，如果您愿意帮忙排查也可以附上。
一开始也获取到了两个相机的图像，后来就有一路报错了，而且重新跑程序又可以获取到
