        你好，请问你用的模组是否为mipi 307，这个默认需要额外5v供电。

            买了两个camera的模组 单独插上每一个都可以点亮，同事插两个就会有上面的提示

              @daxue0116 请问你使用的底板，是否为英伟达官方的开发板b01呢？

                正常情况下，插上两个，会probe到两个。
                你可以看看/dev/video0 /dev/video1是否同时存在。
                另外可以看看

                dmesg | grep 307

                的输出情况。
