报错信息

Cannot load driver 'C:\Keil_v5\ARM\Segger\JL2CM3.dll'.

Possible Reasons:
 - Driver DLL could not be found in the specified path
 - Driver DLL requires additional DLL's which are not installed
 - Required Hardware Drivers are not installed

解决方案

在电脑的PATH环境变量中添加上 C:\Keil_v5\ARM\Segger\ 这个路径,报错完美解决.

具体的参考 网上PATH环境变量添加方式.
