# RT-Thread全志D1移植
|
||
|
||
全志 d1-allwinner-nezha 属于 riscv64 平台
|
||
|
||
## 编译环境搭建
|
||
|
||
- 拉取 RT-Thread Smart的代码仓库 `git clone https://gitee.com/guozhanxin/rtthread-smart.git`
|
||
|
||
### windows 环境
|
||
|
||
- 打开 RT-Thread ENV 工具
|
||
|
||
- 进入 tools 目录 `cd tools`
|
||
|
||
- 拉取 `riscv64`平台的编译工具 `python get_toolchain.py riscv64`
|
||
|
||
- 返回上级目录 `cd ..`
|
||
|
||
- 设置环境变量 `./smart-env.bat`
|
||
|
||
### ubuntu 环境
|
||
|
||
- 打开 ubuntu shell 终端
|
||
|
||
- 进入 tools 目录 `cd tools`
|
||
|
||
- 拉取 `riscv64`平台的编译工具 `python get_toolchain.py riscv64`
|
||
|
||
- 返回上级目录 `cd ..`
|
||
|
||
- 设置环境变量 `source smart-env.sh riscv64`
|
||
|
||
### 编译环境验证
|
||
|
||
- 输入：`riscv64-unknown-linux-musl-gcc -v`
|
||
|
||
## 开发与编译
|
||
|
||
- windows 下使用RT-Thread ENV 工具， `menuconfig` 配置工程，`scons` 编译工程
|
||
|
||
- ubuntu 下 使用shell 终端： `scons --menuconfig` 配置工程， `scons` 编译工程
|
||
|
||
|
||
## 下载验证
|
||
|
||
- 编译完后，通过：mkimage 生成 img 镜像文件，这个img 镜像文件可以使用 U-boot 引导启动
|
||
|
||
- 启动方式一般有：SD卡启动、NandFlash启动、网络引导启动
|
||
|
||
- windows 下使用全志的：`AllwinnertechPhoeniSuitRelease20201225`
|
||
|
||
- 可以使用 xfel 工具进行烧写NandFlash
|
||
|
||
## 运行效果
|
||
|
||
```c
