[求助]请大虾帮忙,我的9S12DG128MPV

[求助]请大虾帮忙,我的9S12DG128MPV

我的9S12DG128MPV新做的试制板,第二块板仿真器能识别芯片,但是在COMMAND窗口看到的芯片总线速度为1.2MHZ,实际我使用的是16MHZ有源晶振,示波器测量频率很准!
请教各位这是什么原因?通过串口初始化的发送速度,也证明总线速度不为8MHZ.另芯片是用手工焊的,效果很差!下面是COMMAND中的相关信息:

救命啊!第一块板子焊完后仿真器(P&E)干脆无法烧写FLASH,不能识别芯片的通讯速度.
检查一下芯片其他引脚的信号是否正常。如XCLKS,MODA,MODB, MODC等。

我做的DG128的开发板,没任何问题的,可能你的管脚电平不对或者没有复位芯片[upload=image/pjpeg]uploadImages/DG128.jpg[/upload]

1。要有复位芯片
2。XCLK,Test等管脚电平要正确
3。芯片要没虚焊

很简单 你的晶振没有起振
可以把你的晶振电路贴出来看看吗?
使用有源晶振 XCLK=>GND!!!!!!!!!!
晶振问题,查看连接,MCU没有检测到外部晶振会自动使用内部时钟源,频率和你所说的值一致
