      sc132通过mipi连接到黑金开发板的FPGA( Xilinx ZU2CG)上,PL端用MIPI CSI的IP核;

      遇到的问题是:上电后,如果不向sc132发送reboot(0x0187)或是reset(0x0104),ip核(包括dphy和csi)内部的寄存器读数相对正常,不影响出图;
      如果向sc132发送reboot或是reset,等待5秒后,dphy寄存器上报clocklane进入退出状态,反复复位dphy不起作用;请问如何解决

        132模组启动大约需要8s。等待5s。理论上MIPI没起来。建议你在reboot摄像头或者reset摄像头之前,先处理好你的接收逻辑,比如退出一下。

        另外 尝试先disable 模组的MIPI-CSI2输出,再reboot试试。

          @veye_xumm disable模组的MIPI-CSI2输出,是指配置streammode=1?初始化的第一条命令就是配置0x0e=1,reboot等待10s、20s都没有变化;调用reboot前,我关闭CSI/DPHY;初始化后,依次开启DPHY/CSI,DPHY的寄存器仍然上报clocklane进入退出状态;我想知道,sc132复位后的MIPI的工作状态的变化过程;

            你好,不好意思没有说清楚怎样停止csi输出。
            我们模组的0x03寄存器,写1则表示使能csi输出,写0则表示停止输出。
            建议你的操作是,重启或者reset模组之前,将这个地址写为0。
            模组重启完成后,会自动恢复的。
