问一个关于在mega8上移植ucos-ii的问题。

我刚接触这方面的东西，想把ucos-ii移植到mega8上，程序是从网上下的，在ICCAVR7中出现，

找了半天也没有资料啊，有谁帮忙指点一下啊。或者说说看那些书啊

icc里带有一个移植的例子不过好像有错，我曾经移植到M162上，M8跑ucos很勉强吧。会不会是你的ROM溢出了，有些模块链接不进去？你换个大点的CPU编译试试。

yangsen。谢谢你。
我换成mega128后，把由ROM的造成问题解决了，但是还有：

你在源程序里找找'push_gset1' 这些变量，看看定义在那里，_OSIntCtxSw' _OSCtxSw' _OSStartHighRdy' 是在汇编里的一个程序是不是没有声明成extern,_OSTickISR可以是汇编语言的也可以是C语言的，不过要用汇编写接口，icc好久不用了，我忘了当时怎么处理这个函数的了

感觉 ucos ii 移植到mega8上意义不大吧

找到我移植到162的文件发给你，你试试
