小白想问一下一致性维护的程序怎么写，各位大佬有没有例程，Cache_flush和Cache_inv该怎么调用，，如果还有硬件信号量的例程就更好了，，求这两种通信例程，
1. cache_wb和cache_inv的函数可以看一下c6678SDK\pdk_c667x_2_0_5\packages\ti\csl\csl_cacheAux.h
2. 硬件信号量例程可以参考下面的帖子。http://www.deyisupport.com/question_answer/dsp_arm/c6000_multicore/f/53/t/4899.aspx
我照着您的硬件信号量例程中的代码使用硬件信号量，但发现没办法Release信号量，或者说Release信号量之后发现isfree函数返回0，能问一下您知道是什么原因吗？
