+## 2. 编译说明
|
|
|
+
|
|
|
+
|
|
|
+| 环境 | 说明 |
|
|
|
+| ------------ | ------------------------------------------------------------ |
|
|
|
+| PC操作系统 | Linux/MacOS/Windows |
|
|
|
+| 编译器 | arm-none-eabi-gcc version 6.3.1 20170620 (release)/armcc/ |
|
|
|
+| 构建工具 | scons/mdk5/ |
|
|
|
+| 依赖软件环境 | Env工具/(MDK或arm-none-eabi-gcc)/git/调试器驱动 |
|
|
|
+
|
|
|
+1) 下载源码
|
|
|
+
|
|
|
+```bash
|
|
|
+ git clone https://github.com/RT-Thread/rt-thread.git
|
|
|
+```
|
|
|
+
|
|
|
+2) 配置工程并准备env
|
|
|
+
|
|
|
+（Linux/Mac）
|
|
|
+
|
|
|
+```bash
|
|
|
+ cd rt-thread/bsp/stm32f7-disco
|
|
|
+ scons --menuconfig
|
|
|
+ source ~/.env/env.sh
|
|
|
+ pkgs --upgrade
|
|
|
+```
|
|
|
+
|
|
|
+（Windows）
|
|
|
+
|
|
|
+>在[RT-Thread官网][1]下载ENV工具包
|
|
|
+
|
|
|
+4) 生成工程(Mac/Linux下请跳过此步骤)
|
|
|
+
|
|
|
+（Windows MDK5）*
|
|
|
+
|
|
|
+```bash
|
|
|
+ scons --target=mdk5 -s
|
|
|
+```
|
|
|
+
|
|
|
+*该板级支持包不支持生成mdk4的工程
|
|
|
+
|
|
|
+（Windows IAR）
|
|
|
+
|
|
|
+```bash
|
|
|
+ scons --target=iar -s
|
|
|
+```
|
|
|
+
|
|
|
+5) 编译
|
|
|
+
|
|
|
+使用MDK或IAR请参见对应教程
|
|
|
+
|
|
|
+（Windows arm-none-eabi-gcc）
|
|
|
+使用以下指令设置gcc路径
|
|
|
+
|
|
|
+```bash
|
|
|
+ SET RTT_EXEC_PATH=[GCC路径]
|
|
|
+```
|
|
|
+
|
|
|
+（Linux/Mac arm-none-eabi-gcc）
|
|
|
+使用以下指令设置gcc路径
|
|
|
+
|
|
|
+```bash
|
|
|
+ export RTT_EXEC_PATH=[GCC路径]
|
|
|
+```
|
|
|
+
|
|
|
+编译（Windows/Linux/Mac arm-none-eabi-gcc）
|
|
|
+
|
|
|
+```bash
|
|
|
+ scons -j4
|
|
|
+```
|
|
|
+
|
|
|
+出现下列信息即为编译成功
|
|
|
+
|
|
|
+```bash
|
|
|
+ LINK rtthread.elf
|
|
|
+ arm-none-eabi-objcopy -O binary rtthread.elf rtthread.bin
|
|
|
+ arm-none-eabi-size rtthread.elf
|
|
|
+ text data bss dec hex filename
|
|
|
+ 41596 356 1456 43408 a990 rtthread.elf
|
|
|
+ scons: done building targets.
|
|
|
+```
|
|
|
+
|
|
|
+
|
|
|
+如果编译正确无误，会产生rtthread.elf、rtthread.bin文件。其中rtthread.bin为二进制固件
|
|
|
+
|
|
|
+## 3. 烧写及执行
|
|
|
+
|
|
|
+烧写可以使用仿真器 ISP等多种方式 此处不再赘述
|
|
|
+
|
|
|
+### 3.1 运行结果
|
|
|
+
|
|
|
+如果编译 & 烧写无误，会在串口1*上看到RT-Thread的启动logo信息：
|
|
|
+
|
|
|
+```bash
|
|
|
+ \ | /

|
|
|
+*默认串口
