这是MDK上的错误

硬件检查了许多次，感觉没问题，请问大神这个问题该怎样解决，是不是晶振的问题啊

不要晶振也能下载程序的

No matching core found 是不是芯片型号不对？再检查硬件，测测JTAG的引脚

肯定有问题。

买的芯片与mini板子上的一样都是stm32f103RBT6，j—link也测了高低电平与mini板j-link相同

原因应经找到，当我把芯片拔下，显示的是相同的信息，，这只有两种解释：一，芯片归西了，二，芯片虚焊了。这是我才买的芯片，从通电到结束芯片没发过一次热，芯片归西的可能性很小，当我拿烙铁再焊焊时，抱着试试看的心情下载了LED跑马灯程序，发现突然能下进去了，一切正常，事实说明芯片虚焊，经历与大家分享一下，希望大家引以为戒
