9s12HA48的问题

我用BDM硬件 CodeWarrior5.1软件中的hiwave.exe读汽车仪表9s12HA48,0xBFF

读0xD8000-0xFBFFF时,只能读出0xD8000-0xDBFF 剩下的没读出来

软件的错误提示也不对:

Error: while reading memory from DC000

Reason: memory not defined in given range

 

但我从0xDC000-0xFBFF读也还是上面的提示 实际上从0xDC000根本没有 说明这个软件不能很好的区分cpu的flash

 

我估计读9s12的软件应该还有一个软件补丁 否则不能很好的读出数据

 

请高手 或厂家高手解决下难题

 

 

我还发现一个问题 实际只要把0x4000-0xFFFF读出来就可以了 因为一擦0x4000 0xD8000也跟着被擦掉了 把0x4000写上0xD8000也跟着写上了

我估计还是软件没有做到最好

但有的cpu跟着擦掉数据后 会丢失数据 还要再写一下  所以说BDM读9s12就是一头雾水 没有民间的设备好用 安全可靠

 

谢!

 

 

分还是要给你 你的方法还是麻烦 但我受到启发 搞定  官方的这个还是不太好用
