我的任务
分享哪位大神有Renesas M16C65系列 UCOS2 移植经验的 求解答，谢谢
IDE: IAR
Hardware: Renesas M16C65
OS: ucos2.56
我从官网上下载了M16C62P的例程做参考，移植了快1周，任务建立也成功，在OSStart()单步调试到RETI后，程序飞了，什么原因，请大神指点，谢谢

OSStartHighRdy:
JSR OSTaskSwHook
MOV.W OSTCBHighRdy, A0 ; ISP = OSTCBHighRdy->OSTCBStkPtr
LDC [A0], ISP
MOV.B #01H, OSRunning ; OSRunning = TRUE
POPM R0,R1,R2,R3,A0,A1,SB,FB

MLGB 任务终于切换成功了！！！
原因在IAR 的编译器
分享一下：
IAR编译器把启动代码还有中断向量全部做到库文件中，工程里面找不到。
给客户的中断接口就是：
#pragma vector=0
__interrupt void OSCtxSw( void )
然而 用仿真器观察发现 像这样的中断函数定义，IAR进入后 直接执行了两行命令：
PUSHM R0,R2,A0
POPM R0,R2,A0
REIT
所以如果我们还是按照官方例程来移植的话，无疑是自寻死路！！！！

那是不是需要在这里加些汇编的代码？

瑞萨也弄算堆栈指针？怎么和CM3一样呢
双堆栈的使用可以参考CM3上移植好的UCOS2。我IAR和UCOS2都还算熟悉，但瑞萨芯片不熟，帮不了忙。[/quote]
谢谢，我马上去看看CM3上的例程

瑞萨的单片机有USP ISP两个堆栈指针，所以要选择一下，目前任务可以切换成功一次，还有许多问题，还在努力DEBUG中。
如果大家有好的建议，请告诉我，不胜感激。

是否初始堆栈(非任务堆栈，main函数使用的堆栈)设置的太小了，你在main函数的初始化函数里用了太多的局部变量导致堆栈溢出了。
初始堆栈一般是在启动汇编中设置的。
