      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
      [ 49.738728] nvcsi 150c0000.nvcsi: csi4_stream_check_status (2) ERROR_STATUS2VI_VC0 = 0x0000000c
      [ 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？

        首先，mipi接口的相机不要热插拔哦，mipi协议并不是usb协议，不支持热插拔的。
        其次，你试一下，只插一个上电。看看能不能正常检测到摄像头？
        如果检测不到，用

        dmesg| grep mvcam

        试一下。

        Questions will be answered as soon as possible, please be patient.
        如果你使用中文，请直接用中文提问。

          可以检测到相机，在/dev下有video0显示

            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：

                    @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。

                          按照原理图来看是匹配的，我来对调mipi总线测试一下

                            有一种可能，你的i2c和mipi是错配的。
