## 2. 硬件开发环境(Hardware development system)
|
||
|
||
开发板(EVK)

|
||
## 3. 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/lpc55s69_evk
|
||
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
|
||
```
|
||
|
||
或者通过 `scons --exec-path="GCC工具链路径"` 命令,在指定工具链位置的同时直接编译。
|
||
|
||
出现下列信息即为编译成功
|
||
|
||
```bash
|
||
LINK rtthread-lpc55s69.elf
|
||
arm-none-eabi-objcopy -O binary rtthread-lpc55s6x.elf rtthread.bin
|
||
arm-none-eabi-size rtthread-lpc55s69.elf
|
||
text data bss dec hex filename
|
||
41596 356 1456 43408 a990 rtthread-lpc55s6x.elf
|
||
scons: done building targets.
|
||
```
|
||
|
||
|
||
如果编译正确无误,会产生rtthread-lpc55s6x.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Flexcomm0串口*上看到RT-Thread的启动logo信息:
|
||
|
||
```bash
|
||
