在KEIL中用JTAG仿真出錯：error：cannot load driver".....JL2CM3.dll" 時的解決方法
報錯：
Error: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
將C:\Keil_v5\ARM\Segger添加到系統環境變量解決
