      您好,我反复确认过了,开发板与我们的板子原理上是一样的。
      现在的问题是我改后的dtb可以完美的搭配预编译的Image使用,那么我是不是可以就此确认我的dtb和我的硬件已经没有问题了?
      另一方面,从dmesg来看ds90ub954的驱动正常运行,我也已经从i2c-7读出了0x30 0x19 0x3b三个地址,那么是不是有可能我需要对cssc132的驱动做出一定的修改才能正常使用?如果是我需要改什么?

        应该是的。你怀疑你自己编译的Image不行吗?

        已经有了0x3b,说明整个fpdlink的初始化通路都成功了,而且跟摄像头的i2c已经通了。
        这种情况,按理说应该正常识别到摄像头了啊。你确认实际摄像头型号跟dtb中的型号一致吗?

          是的,这个是我使用预编译的Image的dmesg,dtb都是同一个

            这个dmesg看,已经成功了,一切正常。

              是的,但是这个Image是从github上下载的,我自己的一直都不行:
              mr123@mr123-emmc3:~$ dmesg |grep cssc

              [ 1.712914] cssc132: probe of 8-003b failed with error -121

              mr123@mr123-emmc3:~$ i2cdetect -y -r 7
              0 1 2 3 4 5 6 7 8 9 a b c d e f

              70: -- -- -- -- -- -- -- --

              所以就现在来说我比较怀疑cssc132驱动的问题。
              或者说还有其他原因会导致这个现象吗?
              在此过程中我只改变的Image。

                看一下你的dmes全部内容,954这颗芯片的初始化,难不成跑到了132模组初始化后面去了?
                或者你吧整个dmesg的输出保存成文件,post上来我看看。

                    您好,
                    是这样的,确实是先初始化的cssc132然后再初始化的ds90ub954:

                    你看一下你合并我们的代码部分,注意makefile和kconfig中954和132两个驱动的先后顺序。 这个影响调用顺序。

                      好的,谢谢您了。
                      另外我今天新到四个cssc132相机,如果想要全部识别到的话,我是否需要对其进行硬件上的修改?

                        不客气。 我不太清楚你买的订单的硬件信息。 可以看我们这页文章:
