      硬件是有转接板的,量过了线序是对应的上的:

        1处排线插歪了。
        2处的排线没有用处建议去掉,保证mipi信号的质量。

        不过感觉你这个的核心问题还是0bfbcbe0-cef6-42c7-848c-47fe84188a9e-image.png

          读取相机的datarate返回是-1代表什么意思。

            @jihua 应该是这个版本的固件还没有支持这个寄存器。不影响正常出图和对接的。

              内核打印的信息显示datarate是1.5G,用示波器测量不到时钟波形,只能测到数据波形,这个模块的实际datarate是多少的?现在抓图的时候,内核驱动报crc错误,怀疑是排线太长或者datarate对不上。

                按照1.5G配置是没问题的,我们在多个rk3588上面都调通的。
                你用的排线是多长的?可否拍个照片我看看。

                  排线长度有26厘米长

                    @jihua 线长也没有很夸张。你测测摄像头这端,入口地方的3.3V供电,实际电压是多少?

                      VCC3V3 测量到是3.3V,MIPI_CK_N 时钟是固定的吗?时钟是多少的?设置帧率后这个时钟会变吗?

                        @jihua 相机是固定的1188M,3588那头设置为1500M是没问题的。
                        你把现在报的错发给我看看。

                            @jihua 我们在rk平台没有遇到过这个问题。看ecc2这个错误提示的话,像是mipi信号劣化了。
