求助,请各位大侠帮忙分析下是什么问题
我刚做的电路板,晶振是普通的8M晶振,用MULTILINK BDM调试时发现,总是说和目标板联系不上。 出现过以下几种提示:
1. "Target MCU has no clock or Wrong BDM Clock speed is used or derivative is secured!"
2..出现IO_DELAY_COUNT输入窗口,也还有search,autodetect自动检测!使用自动检测后。
3.出现HI-WAVE窗口,提示Failed to find communication speed!点击确定后...
4.出现窗口提示,communication to the target failed!(target MCU has no clock or wrong BDM clock speed is used or derivative).
