好久没摸过战舰版了，这次捡起来完全是冲着国产的RT-Thread，想好好学习操作系统，提升一下自己的水平，结果问的问题自己都不知道在问什么!好在有老师的不厌其烦地指导下终于跑出了人生中的第一次系统。以后会继续努力的！(发图片提示Server IO Error )
现在总结一下经验教训：
1.系统没跑起来主要是搞错战舰版的串口，一直在用uart2连接串口，后来查看 战舰的原理图才发现问题所在！
2.系统调试缺少经验，花费很多时间在DEBUG上。Dialog DLL和Parameter要改为DARMSTM.DLL，TARMSTM.DLL，和-pSTM32F103ZE。Debug-Connect改为Under Reset.
3.直接用的战舰的BSP，搞了好久才发现CubeMX_Config里的SYS-Debug设置的No Debug!
