注意env工具的路径必须是非中文无空格。

# 下载源码

双击打开\env_released_1.2.0\env\env.exe

输入git clone https://github.com/RT-Thread/rt-thread
回车

# 安装MDK
https://www2.keil.com/mdk5
下下载MDK v5.36和兼容包
安装和谐过程略,可以网上搜索。

# 安装JLINK
略

# 安装MDK设备数据库
从
http://www.nuvoton.com.cn/products/microprocessors/arm9-mpus/nuc980-industrial-control-iot-series/nuc980df61yc/?group=Software&rt=Board%20Support%20Package%20(BSP)&tab=2

下载NuMicro ARM9 Device Database for Keil 1.02

双击安装NuMicro ARM9 Device Database for Keil 1.02.exe,安装过程会自动选择Keil的安装路径。

# 导出MDK工程
由于使用MDK开发环境较多,所以这里导出MDK工程,后续均基于此开发。
- 输入cd rt-thread\回车,进入源码目录,
- 输入cd bsp\nuvoton\nk-980iot\回车,进入开发板对应的源码目录,
- 输入menuconfig --generate回车,进行配置,
- 输入 pkgs --update回车,更新包,如下提示更新完成

- 输入scons --target=mdk5回车,生成工程。

生成的工程为\env_released_1.2.0\env\rt-thread\bsp\nuvoton\nk-980iot\project.uvprojx

使用MDK打开project.uvprojx即可。后续基于该工程进行开发。

如果打开工程提示
Device not found
则使用scons --target=mdk4生成工程。

# 编译

双击\env_released_1.2.0\env\rt-thread\bsp\nuvoton\nk-980iot\project.uvprojx打开工程。

提示
..\libraries\nuc980\rtt_port\drv_emac.c(458): error:  #20: identifier "old_level" is undefined

搜索SYS_ARCH_DECL_PROTECT发现该宏定义在\components\net\lwip\lwip-2.1.2\src\include\lwip\sys.h
在 \bsp\nuvoton\libraries\nuc980\rtt_port\dev_emac.c前添加#include <lwip/sys.h>即可。

编译结果如下:

# 问题

已提交至 https://github.com/RT-Thread/rt-thread/issues/5636

另外编译告警
```
.\Objects\rtthread.axf: Warning: L6330W: Undefined symbol UtestTcTab$$Base (referred from utest.o). Unused section has been removed.
.\Objects\rtthread.axf: Warning: L6330W: Undefined symbol UtestTcTab$$Limit (referred from utest.o). Unused section has been removed.
```
是因为没有使用utest所以没有UtestTcTab段代码，可以先忽略。
