TI中文支持网使用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

Louis：
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？

回复 Louis:
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？

回复 Louis:
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？

回复 zhouzhuan2008 zhouzhuan2008:
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。
