求助关于c6748加密的问题

现在我的ini文件中已经设置bootExitType=securewithsk,可是我在执行setuserkey()函数中的resultval=SK——registerscwp（）函数时总是返回的值和scw不相等是什么原因呢？

Tony Tang：

看一下返回值到底是什么，对照下面说明，看是出的什么错。

Syntax int SK_registerSCWP(scwp, numSC);Parameters int *scwp – pointer to an integer owned by the Operating System that tracks the current secure context.unsigned numSC – number of secure contexts into which the single secure stack block is dividedReturn Value SCWP, if no errorSK_EPRIV if not called from supervisor privilege levelSK_EINUSE if any secure contexts are currently allocatedSK_EINVAL if scwp is not word-alignedSK_ECTX if numSC is bad (can only be 1, 2, 4 or 8)Constraints Must be called from supervisor privilege

回复 Tony Tang:

返回的是-1（#define SK_ESTACK -1 /* bad secure/non-secure stack */），例程是按照指导文档编写的。请问这个是什么原因引起的？
