      请问,使用5.10版本的驱动程序,但是加载失败了,可能是什么原因呀?

        @lin 系统启动后不需要手动insmod,系统会自动根据device tree去查找和加载对应的驱动。
        而且看你的提示已经成功probe到了。

            @lin 后面两个应该是驱动中某个函数出错了。你可以看一下完整的dmesg信息就知道了。 不知道你有没有改我们的驱动的.c的源码,一般来说是没有必要改的。

                看你的错误提示信息,是mvcam_probe函数中,大约调用到一个strcmp字符串拷贝的地方,访问了0地址。
                你需要跟踪一下代码。虽然你没有改动我们相机驱动,但是你用的kernel是跟我们的不同,这个是可能导致此问题的原因。

                  @veye_xumm 我修改了一下设备树,但是拓扑图中还是没有相机节点,可能是什么原因?

                    @lin 应该还是设备树配置的问题。
