在原子的UCOS例子里移植LCD文件，每到LCD初始化的时候就跑飞了，LED任务灯也不亮了

用的是V1.9 MINI

你没有开串口，因为原子的LCD初始化中有通过串口打印LCDID

回复【3楼】2449164582:
---------------------------------
谢谢，我把这句去掉了，// printf(" LCD ID:%x\r\n",DeviceCode);
就可以了，还是没有沉下心分析代码，多谢您的帮助。

还有一个问题就是因为跑飞，所以就用JTAG SW的方式仿真了一下，每次都是在GPIO_PinRemapConfig(GPIO_Remap_SWJ_JTAGDisable , ENABLE);执行不下去的，这是为什么呢？
