前言本文以星火一号开发板为例记录STM32命令行开发环境在Linux上的部署，用以替代Windows上的RT-Thread-studio。RT-Thread开源，但RT-Thread-studio不是开源软件。

Windows方案

该方案使用scons+gcc-arm-none-eabi+openocd,可以和Vscode等等配合使用.

拉取源码

https://github.com/Dichgrem/sdk-bsp-stm32f407-spark-template.git

安装依赖

安装 Scons 构建工具

pip install scons

安装 gcc-arm-none-eabi 工具链

在官网下载gcc-arm-none-eabi-10.3-2021.10-win32.exe,安装后使用以下命令设置环境变量

$env:RTT_EXEC_PATH="C:\Program Files (x86)\GNU Arm Embedded Toolchain\10 2021.10\bin"

$path = [Environment]::GetEnvironmentVariable("Path", "Machine")
[Environment]::SetEnvironmentVariable(
  "Path",
  "$path;C:\Program Files (x86)\GNU Arm Embedded Toolchain\10 2021.10\bin",
  "Machine"
)

安装 openocd 调试/烧录工具

scoop install openocd
openocd --version

安装串口调试工具（可选，也可以用其他串口工具）

pip install pyserial

编译固件

进入项目目录并在projects下使用scons编译固件,编译结果为rt-thread.bin和rt-thread-elf

sdk-bsp-stm32f407-spark
❯ cd ./projects/03_driver_als_ps

scons: done building targets.

烧入测试

使用openocd指定开发板对应的cfg并烧入，起始地址为0x08000000

openocd -f interface/stlink.cfg -f target/stm32f4x.cfg
openocd -f interface/stlink.cfg -f target/stm32f4x.cfg -c "program rtthread.bin 0x08000000 verify reset exit"

串口连接

烧入完成后我们可以使用pyserial的这个命令连接到串口，退出使用Ctrl+]退出

python -m serial.tools.miniterm COM3 115200

注意Windows上和开发板连接的串口可能是COM3,COM4等等，需要和实际的相符，可以在设备管理器中查看.

Ubuntu 方案

拉取源码

https://github.com/Dichgrem/sdk-bsp-stm32f407-spark-template.git

安装依赖

sudo apt update
sudo apt install -y git python3 scons openocd stlink-tools gcc-arm-none-eabi gdb-multiarch

编译固件

scons -j$(nproc)

测试连接

使用USB线连接开发板和开发PC，并使用lsusb命令查看是否出现：

lsusb
Bus 001 Device 004: ID 0483:374b STMicroelectronics ST-LINK/V2.1

添加成功后可以使用这个命令来检测是否连接成功：

❯ st-info --probe
Found 1 stlink programmers
  version:    V2J35S26
  serial:     0671FF373654393143244522
  flash:      1048576 (pagesize: 16384)
  sram:       196608
  chipid:     0x413
  dev-type:   STM32F4x5_F4x7

如果你将Ubuntu安装在QEMU等虚拟机中，需要在libvirt中使用Add_hardware添加usb设备。

烧入测试

编译成功后你应该会看到有一个rtthread.bin在目录下，这就是我们编译出来的系统！

在烧入之前，我们可以备份一下原来的系统：

st-flash read firmware_backup.bin 0x08000000 0x100001

随后使用如下命令烧入系统：

st-flash write rtthread.bin 0x08000000

串口连接

除了USB之外我们还可以使用串口连接：

sudo apt install picocom
picocom -b 115200 /dev/ttyACM0

可以使用ctrl + A 然后 ctrl + x退出。

其他Tips

使用Cmake编译

通过官方文档可以得知除了scons外还可以使用Cmake来编译.

首先找到编译器的路径，并export，我这里是Nixos的路径，如果你使用其他发行版注意修改：

❯ which arm-none-eabi-gcc
/nix/store/v9p5md3d4aaqwc9i9hlaxkl7nawd9vrc-gcc-arm-embedded-14.3.rel1/bin/arm-none-eabi-gcc
export RTT_EXEC_PATH=/nix/store/v9p5md3d4aaqwc9i9hlaxkl7nawd9vrc-gcc-arm-embedded-14.3.rel1/bin
export RTT_CC=gcc

随后使用指令scons --target=cmake：

❯ scons --target=cmake

scons: Reading SConscript files ...
Newlib version:4.5.0
Update setting files for CMakeLists.txt...
Done!
scons: done reading SConscript files.
scons: Building targets ...
scons: building associated VariantDir targets: build
CC build/applications/main.o
LINK rt-thread.elf
arm-none-eabi-objcopy -O binary rt-thread.elf rtthread.bin
arm-none-eabi-size rt-thread.elf
scons: done building targets.

可以看到生成CmakeLists.txt成功，随后开始构建：

❯ cd ./build       
❯ cmake ..  
CMake Warning (dev) at CMakeLists.txt:43:

使用make命令编译：

Nixos

虽然Nixos上没有RT-Thread-studio这个包，但是可以用flake.nix很方便的搭建一个开发环境：

{
  description = "STM32 && RT-Thread development environment";
  inputs.nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
  outputs = { self, nixpkgs }:
  let
    supportedSystems = [ "x86_64-linux" "aarch64-linux" ];
    forEachSupportedSystem = f: nixpkgs.lib.genAttrs supportedSystems (system: f {
      pkgs = import nixpkgs { inherit self system; };
    });
  in
  {
    devShells = forEachSupportedSystem ({ pkgs }: {
      default = pkgs.mkShell {
        packages = with pkgs; [
          python312
          scons
          openocd
          stlink
          stlink-tool
          gcc-arm-embedded
          picocom
          renode-bin
        ];
      };
    });
  };
}

使用Renode

如果没有真实的开发版，可以使用Renode来进行仿真模拟：

# 启动renode
renode

# 创建机器
(monitor) mach create

# 加载STM32F407平台
(monitor) machine LoadPlatformDescription @platforms/boards/stm32f4_discovery.repl

# 加载你的固件
(monitor) sysbus LoadELF @/你的路径/rtthread.elf

# 打开串口窗口（finsh会显示在这里）
(monitor) showAnalyzer sysbus.usart1

# 启动仿真
(monitor) start
