+* 如果安装Pack后，Keil依然报以下这类错误，可能是之前安装了 Keil v4 兼容包 (MDK v4 Legacy Support) 导致的，请尝试**卸载此包或重新安装 Keil v5**。
+
+`Error #540: 'Keil::Device:StdPeriph Drivers:ADC:1.0.1' component is not available for target 'X-Track'`

   ### 注意
   **不要修改芯片选型**，因为修改芯片选型后启动文件会重新生成，堆栈大小会恢复默认值，而使用默认的栈大小会导致**栈溢出**。现象是启动后立即蓝屏，提示发生**HardFault**(如下图所示)，串口会输出详细的错误信息。如果确实需要修改芯片选型，请参考工程原始的启动文件进行修改。
