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
