      这是检查image和dtb以及系统状态检测的结果

        软件的操作看起来是正常的,现在上电检测不到摄像头。怀疑是硬件连接的问题。
        请检查一下供电,排线方向。

          @veye_xumm排线应该没有问题,我觉得可能是dbt的问题,sc130m用的dbt是从mv-mipi-cam中找吗

                好久没有回信我以为你已经解决了呢。
                你用的线是我们标配的15pin的对吧? nx那端接的怎么样?
                另外执行一下

                sudo dmesg | grep mvcam
                

                发上来看一下。

                    @veye_xumm 对的,用的是15pin的,这是我的image和dbt的替换路径,我现在重刷系统为jetpack4.6.1ff5177911507f699e82c427d69e9c0d.jpg 2cc2d2b25616d50735a8a312a0c06df.jpg ![cb948cb1c8ab9617d31e464dc2a61b3.jpg](/assets/uploads/files/1699235246201-![0_1699235299538_82cd91eb3c6632b5ced60ed97c8a5da.jpg](正在上传 100%)

                      @stark 现在核心的问题是i2c detect不到,导致检测不到。应该不是你系统版本的差异。
                      你有万用表或者示波器吗?
                      测量一下供电,i2c波形。

                          @stark 你先测测两个杜邦线的供电吧。示波器不会用的话,那就没办法测试了。
                          你的nx主板是nVidia官方的吗?
                          可以尝试执行

                          sudo i2cdetect -y 9
                          sudo i2cdetect -y 10
                          

                          看一下有没有0x3b的设备能probe到,来确认一下i2c问题。

                                @stark 按理来说,虽然是国产套件,但是camera接口和i2c他们应该是兼容英伟达官方的才对。你可以跟卖家做一下确认。

                                    @stark 不好意思,得加上一个参数

                                    sudo i2cdetect -y -r 9
                                    sudo i2cdetect -y -r 10

                                          这是我在板子上命令行的操作整理了下,应该没有问题吧

                                            根据你的步骤,看起来是没问题的。 唯一的一个疑问,就是你用的这个第三方的板子是否完全兼容英伟达官方的版本。

                                            此外,其实i2cdetect本身不需要依赖到你的驱动配置无误。 只要给到我们模组正确的供电,另外就是power ENABLE引脚拉高,之后应该就能检测到了。
