|
| ------------ | ------------------------------------------------------------ |
|
|
|
|
|
|
| PC操作系统 | Linux/MacOS/Windows |
|
|
|
|
|
|
| 编译器 | arm-none-eabi-gcc version 6.3.1 20170620 (release)/iar |
|
|
|
|
|
|
| 构建工具 | scons/iar |
|
|
|
|
|
|
| 依赖软件环境 | Env工具/(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/amebaz
|
|
|
|
|
|
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IAR，则需要生成工程
|
|
|
|
|
|
|
|
|
|
|
|
4) 下载package
|
|
|
|
|
|
|
|
|
|
|
|
amebaz配套的驱动库以package形式提供，故需先下载对应的package(realtek-ameba)，请使用env下载package
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
pkgs --update
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
5) 生成工程(Mac/Linux下请跳过此步骤)
|
|
|
|
|
|
|
|
|
|
|
|
（Windows IAR）
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
SET RTT_CC=iar
|
|
|
|
|
|
scons --target=iar -s
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
*该板级支持包不支持生成mdk的工程
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
6) 编译
|
|
|
|
|
|
|
|
|
|
|
|
使用IAR请参见对应教程
|
|
|
|
|
|
|
|
|
|
|
|
（Windows arm-none-eabi-gcc）
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
SET RTT_EXEC_PATH=[GCC路径]
|
|
|
|
|
|
```
|
