      我们的SYS_RSTn对应的是你的17,现在是NC的,我们内部有上拉,这样i2c应该直接就是通的。你是接到i2c-7上了吗?另外,你的fpc线方向有没有插反了?

            不好意思,我之前说的就是SYS_RSTn引脚的意思。

            拍一下你硬件连接的照片我看看。

              @veye_xumm复位端未与底板连接,由于相机上上拉的原因应该是属于持续工作的状态吧? 驱动没加载上的话,i2cdetect 能检测到挂载设备吗?868fc94a-ccc9-477f-ba64-a417a027d43f-image.png

                是的。 你这个camera3是对应的i2c-7吗? 如果无误,问题进展到这一步,我只能说上万用表,示波器量一下吧。先量供电,再量I2C。

                  @veye_xumm 用示波器测量i2c应该是什么情况能说明设备被连上了呢?

                    可以用mv_mipi_i2c.sh脚本执行读写寄存器操作,同时观察示波器上面波形。
