一、为什么移植RT-Thread RT-Thread是一个完全国产化的嵌入式实时多线程操作系统，看到AT32例程并没有关于RT-Thread的移植，鉴于AT32F425最大FLASH只有64K，故移植RT-Thread极简版，也就是RT-Thread Nano。 二、准备工作 1、AT32F425 BSP以及固件库。 下载链接：雅特力科技 : 32位微控制器的创新领导者! (arterytek.com) 2、RT-Thread Nano源码安装包 方法一、通过KEIL安装 1）打开 MDK 软件，点击工具栏的 Pack Installer 图标
2）点击右侧的 Pack，展开 Generic，可以找到 RealThread::RT-Thread，点击 Action 栏对应的 Install ，就可以在线安装 Nano Pack 了。另外，如果需要安装其他版本，则需要展开 RealThread::RT-Thread，进行选择
方法二、从官网下载即可。 https://www.rt-thread.org/download/mdk/RealThread.RT-Thread.3.1.5.pack 下载完，直接双击即可。 三、移植流程 1、新建AT32F425的基本工程（官方给的是所有的工程共用BSP） 1）复制官方的library到自己所新建的文件夹，并且添加at32f425_board.c、at32f425_board.h、at32f425_clock.c、at32f425_clock.h、at32f425_int.c、at32f425_int.h、main.c、at32f425_conf.h文件。 2）添加相应的C文件、添加.h文件目录。然后编译。 2、添加RT-Thread Nano到工程 1）点击工具栏Manage Run-Time Environment图标，如下图： 2）在 Manage Rum-Time Environment 里"Software Component" 栏找到 RTOS，sel 栏选择 RT-Thread，然后勾选 kernel，点击 "OK" 就添加 RT-Thread 内核到工程了。展开RTOS就可以看到添加到工程的文件。如图所示。
3、适配RT-Thread Nano 1）在at32f425_init.c文件中注释HardFault_Handler、PendSV_Handler、SysTick_Handler，这些已经由RT-Thread实现了。 2）在borad.c中实现系统时钟配置和OS tick配置。然后在main.c函数里面加入LED显示配置，编译，检查是否移植正确 /*
