ti8168 tvp5158 hdvpss驱动代码运行时阻塞

Other Parts Discussed in Thread: TVP5158

我基于dvrdk开发包进行开发,hdvpss版本是01_00_01_28,板子使用4颗tvp5158作为videodecoder,demo程序运行时会阻塞在tvp5158的驱动里面,具体在vpsdrv_tvp5158Api.c文件的Vps_tvp5158AllocObj函数的Vps_tvp5158Unlock()这一句,实际就是Semaphore_post ( gVps_tvp5158CommonObj.lock );这个是操作系统提供的接口,而且按常理应该是能100%执行成功的,有没有人知道可能会是什么原因引起的,或者有谁碰到过类似问题解决了的,还望不吝赐教!
