      亚博Xavier NX，软件版本是Jetpack4.4,L4T版本r32.4.3，硬件上我们插了2个镜头，一个csi的，一个VEYE-MIPI-327，dev下面本来有一个video0(是那个csi的),

      针对相机VEYE-MIPI-327按照网站http://wiki.veye.cc/index.php/VEYE_CS_Camera_for_Jetson_TX2/zh的操作把bsp包中的kernel_image\Image_l4t_r32.4.3_veyecam_signed_4_xavier下的image、Image.sig，以及Xavier-NX\JetPack_4.4_Linux_JETSON_XAVIER_NX_DEVKIT\dts dtb\VEYE-MIPI-327目录下的tegra194-p3668-all-p3509-0000.dtb拷贝到boot目录下，然后修改了/boot/extlinux/extlinux.conf，增加
      FDT /boot/tegra194-p3668-all-p3509-0000.dtb
      重新启动后连原来有的video0都不见了

        你好。
        我们提供的dtb指定了两个camera都是VEYE-MIPI-327，所以如果替换了我们的dtb，则原有csi摄像头无法探测到是正常的。
        如果想要兼容两个，则需要根据dts的代码，分别为两个mipi接口指定两种摄像头。

        此外，是不是VEYE-MIPI-327也没有探测到？
        建议根据文档的3.7 Image和DTB更新成功了吗？查看。

        PS：你的板子采购自亚博，但是是英伟达官方版本，对吧？

          @veye_xumm 板子是从亚博买的，用过他们提供的系统，也用过英伟达最新的官方版本，结果都是一样的，两个都没看到了。
          3.7的检查ls /sys/bus/i2c/drivers/用亚博的系统时只看到veye327 csx307 cssc132 目录的存在，但是没有veyecam
          用官方版本记得是都存在
          ls /proc/device-tree/cam_i2cmux/i2c@*的 结果是:
          /proc/device-tree/cam_i2cmux/i2c@0:
          '#address-cells' name rbpcv2_veye327_a@3b '#size-cells'
          linux,phandle phandle reg

          /proc/device-tree/cam_i2cmux/i2c@1:
          '#address-cells' name rbpcv2_veye327_c@3b '#size-cells'
          linux,phandle phandle reg

            @veye_xumm 你的意思是不是用你们dtb就只能用同一个类型的镜头？那我只用一个327应该也是可以的，对吗？

              是的，看起来你的系统应该搞对了。
              327不知你用的哪款，如果是327E（双板）这款，是需要杜邦线独立供电的。
              可以重点检查一下供电，还有fpc排线的情况。

                  @veye_xumm 应该是硬件有问题，同事重新量了电压，发现有不对。好像还真的是327E。我们弄弄硬件再看看。谢谢。

                          @veye_xumm 我们用另外一套合众Xavier NX系统，也按照3.5升级，video也没有了。现在已经是单独供电了，3.7的检测结果如下:

                          基本跟上次一样，但是我发现dmesg | grep veye327的结果有报错
                          8f6e289b-f141-47b7-8036-0d59d09b3294-image.png
                          是什么问题呢？

                            你需要问一下他们，板子的原理图（摄像头相关部分）是不是跟官方的不同。

                              @veye_xumm 他们说 IIC的控制有些不一样。这样是就没办法了吗？

                                当然有办法。 如果他们系统是开源的，您可以自己将我们的dts源码和驱动源码移植到他们的系统中去。
                                如果他们系统是封闭的，此工作可以由他们来完成。
                                因为我们的产品驱动和dts都是开源的。

                                  @veye_xumm 我们的L4T版本是Jetpack4.4,L4T r32.4.3，您的意思让我们自己拿你们的源码编译那些dtb\image文件？
                                  我是菜鸟，不是太懂，没找到哪里下载tegra-l4t-r32.4.3、source_sync.sh、nvidia_sdk这些程序？你们的源码是不是都在nvidia_jetson_veye_bsp目录下的？
                                  能不能麻烦您详细跟我说说怎么做，

                                    我的意思是，你现在的系统，跑的是亚博他们的linux kernel。你要首先跟亚博沟通，确认他们的代码是否是开放的。
