|||
|
|
|||
|
## 1. 简介
|
|||
|
|
|||
|
STM32F4 是由意法半导体推出的Cortex-M4内核的高性能单片机
|
|||
|
包括如下硬件特性:
|
|||
|
|
|||

|
|||
|
| -- | -- |
|
|||
|
|芯片型号| STM32F4全系列 |
|
|||

|CPU| Cortex-M4 |
|
|||
|
|主频| 84MHz-208MHz |
|
|||
|
|
|||
|
## 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/iar |
|
|||
|
| 构建工具 | scons/mdk5/iar |
|
|||
|
| 依赖软件环境 | Env工具/(MDK或IAR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/stm32f4xx-HAL
|
|||
|
scons --menuconfig
|
|||
|
source ~/.env/env.sh
|
|||
|
pkgs --upgrade
|
|||
|
```
|
|||
|
|
|||
|
(Windows)
|
|||
|
|
|||
|
>在[RT-Thread官网][1]下载ENV工具包
|
|||
|
|
|||
|
3) 配置芯片型号
|
|||
|
|
|||
|
(Linux/Mac)
|
|||
|
|
|||
|
```bash
|
|||
|
scons --menuconfig
|
|||
|
```
|
|||
|
|
|||
|
(Windows(ENV环境中))
|
|||
|
|
|||
|
```bash
|
|||
|
menuconfig
|
|||
|
```
|
|||
|
|
|||
|
在menuconfig页面配置并选择对应的芯片型号,若开发环境为MDK/IAR,则需要生成工程
|
|||
|
|
|||
|
4) 生成工程(Mac/Linux下请跳过此步骤)
|
|||
|
|
|||
|
(Windows IAR)
|
|||
|
|
|||
|
```bash
|
|||
|
SET RTT_CC=iar
|
|||
|
scons --target=iar -s
|
|||
|
```
|
|||
|
|
|||
|
(Windows MDK5)*
|
|||
|
|
|||
|
```bash
|
|||
|
scons --target=mdk5 -s
|
|||
|
```
|
|||
|
|
|||
|
*该板级支持包不支持生成mdk4的工程
|
|||
|
|
|||
|
**MDK 与 IAR 在生成完成工程之后一定要在工程中手动选择一次芯片信号,否则会产生严重编译错误**
|
|||
|
|
|||
|
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(WindowsLinux/Mac arm-none-eabi-gcc)
|
|||
|
|
|||
|
```bash
|
|||
|
scons -j4
|
|||
|
```
|
|||
|
|
|||
|
出现下列信息即为编译成功
|
|||
|
|
|||
|
```bash
|
|||
|
LINK rtthread-stm32f4xx.elf
|
|||
|
arm-none-eabi-objcopy -O binary rtthread-stm32f4xx.elf rtthread.bin
|
|||
|
arm-none-eabi-size rtthread-stm32f4xx.elf
|
|||
|
text data bss dec hex filename
|
|||
|
41596 356 1456 43408 a990 rtthread-stm32f4xx.elf
|
|||
|
scons: done building targets.
|
|||
|
```
|
|||
|
|
|||
|
|
|||
|
如果编译正确无误,会产生rtthread-stm23f4xx.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2*上看到RT-Thread的启动logo信息:
|
|||
