      @lin 这款相机在4lane模式下,才可以支持到120fps。 你需要配置一下lanenum,然后再配置fps。
      此外,任何时候你都可以通过maxfps指令来读取当前支持的最大帧率。

        @veye_xumm 我将0x3b的帧率和lanenum进行了修改后,在media-ctl拓扑图中找不到这个相机了,没改过的0x3c还是可以正常找到,什么原因呀?

          @lin 不好意思,昨天忘了说一个事情。改成4lane之后,用脚本paramsave保存一下参数。
          然后,需要修改一下dts中的lane的定义——需要改为4lane才可以。
          此外,需要使用新版本的ADP-MV2,这个板子增加了22pin的那个排线接口。你可以看一下跟你手上的ADP-MV2是不是一样。

            @veye_xumm 那3588还能同时接两个相机吗?现在是每个相机是2lane的

              rk3588本身具备同时输入两个4lane的MIPI信号的能力的。关键是你的主板是否引出了对应的接口?

                只有这一个Mipi接口,2x2lane或者1x4lane,没有别的方法可以提高曝光的时间了吗?除了通过提高lane数,修改相机帧率之外的方法?

                  @lin 你现在用的这个板子,只引出来了2个2lane的mipi接口。无法完成接入两个4lane的相机的工作。你需要换个板子了。

                    @veye_xumm 没有其他方法了吗?只能通过更换成2x4lane的才能提高曝光时间了吗?

                      @lin 是的。
                      不过你要是用视频流模式当然可以咯。
