DM8168 加载vpsss.ko问题

使用EZSDK开发包，安装ezsdk中的手册TI81XX_Video_Capture_Driver_User_Guide.pdf步骤操作，遇到下面问题：请问是什么原因造成的

    可能是一些aragp pre-installed 的 *.ko 与vpss.ko有冲突，下面的链接是否能帮到你？

    我查看了，应该是没有驱动重复加载导致冲突了。

    您觉得还有别的什么方面的原因造成了这个问题吗？

    另外还有别的客户反映过这个问题吗？

    另外，我查看了内核源代码，发现问题是出在下面这个地方：

    /* Remote notification is not initialized */
    #define NOTIFY_E_NOTINITIALIZED -16

    /* Stamp indicating that the Notify Shared Memory driver on the
    * processor has been initialized. */
    #define NOTIFYSHMDRIVER_INIT_STAMP 0xA9C8B7D6

    /* Send a notification event to the registered users for this
    * notification on the specified processor. */
    int notify_shm_drv_send_event(struct notify_driver_object *handle,
    u32 event_id, u32 payload, bool wait_clear)
    {

    .............

               /* Check whether driver on other processor is initialized */

               if (obj->other_proc_ctrl->recv_init_status != \

                      NOTIFYSHMDRIVER_INIT_STAMP) {
               /* This may be used for polling till other-side driver is ready,
              * so do not set failure reason. */
               status = NOTIFY_E_NOTINITIALIZED;
               goto exit;
       }

    ...........

    }

    我的理解是共享内存初始化失败？导致了这个问题的产生。您有什么看法呢？

    后面问题解决了吗？ 我也怀疑共享内存有问题，因为我的容量不一样，改了这部分设置。比较麻烦的是，我的芯片方案除了cpu，其它几乎都变了，所以很难找问题。
