      @veye_xumm 590870fc-9b59-4a3e-8748-b0297bfc9599-image.png 你好,模组输出的时钟是多少,还有H-blanking 和 V-Blanking

        mipi信号的clock是数据速率的一半。
        H-Blank和V-Blank跟具体的roi设置和帧率设置有关系。不过我觉得你fpga接收只要设置好最小可能值就行了。
        H-blank:180
        V-blank:25

                              降低帧率的话,V-Blanking会加大。比如默认是1080p@60fps,对应V-Total=V-Active+V-Blanking=1080+25;那么配置成30fps的时候,V-Total会配置为原来的2倍,增加的全部会加到V-Blanking中。

                                      @canglin 不好意思,看错了,读出来的数是0xd9878,速率是870Mbps

                                        @canglin 应该是891Mbps/lane; csi_clk应该是这个值的一半,因为是双沿的。
