      我现在只在设备树添加一个相机,设备树中对相机时钟有要求吗?

      没有要求,相机自己有时钟。
      OK3588-C-Camera.dtsi中,i2c-7这一路,你可以参考一下下面这部分代码。

        @veye_xumm请问,你们调试的时候有遇到这种情况吗?没有数据流输出,一直阻塞 16a1f873-dc28-49a3-9b52-47e9ce0a76fb-image.png

          @lin 你是否用的是外触发模式?
          查看一下dmesg是否有报错?
          确认一下dts中关于mipi接口配置是否正确。

            内核打印信息:1.txt
            还有您说的mipi接口配置是指链路设置还是mipi_csi2节点设置?

              整个数据通路都得配置好才行。

                  看你的拓扑图:

                  - entity 48: m00_b_mvcam 7-003b (1 pad, 1 link)

                                  -> "rockchip-csi2-dphy1":0 [ENABLED]
                  

                  你这边设定i2c-7接口配套的mipi硬件接口是:csi2-dphy1
                  真的是这样的吗?

                  我给你的我们调过的那个dts,用的可是csi2-dphy0啊!

                            OK3588-C这个开发板,我之前贴的这个dts是调试过的。

                            没有要求,相机自己有时钟。

                            你直接用这个dts,然后配合我们官方发布的驱动。
                            在加上这个链接提示的问题点:https://wiki.veye.cc/index.php/FAQ_on_RK35xx_Platform/zh

                            应该可以直接调通i2c-7这一路才对。

                                    应该跟这个没关系。

                                    你这个命令也没有问题。

                                    很奇怪,按理说应该不会有这些mipi协议上的错误,请拍一下你的硬件系统图给我看看。

                                        确认下这个3.3V是否稳定输出(幅值>3.2V)。100mA@1.2V(或1.5V)看起来功率是不够用的。

                                          功率不够需要怎么解决,外加电源吗?功率需达到多少可以呢?
