STM32L476-nucleo 板级支持包

1. 简介

STM32F411-nucleo 是由意法半导体推出的搭载Cortex-M4内核的高性能微控制器开发板包括如下硬件特性

硬件 描述
芯片型号 STM32F411RE
CPU Cortex-M4
主频 100MHz
Flash 512kB
SRAM 128KB

stm32f411

2. 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/
构建工具 scons/mdk5
依赖软件环境 Env工具/(MDK或arm-none-eabi-gcc)/git/调试器驱动
  1. 下载源码
    git clone https://github.com/RT-Thread/rt-thread.git
  1. 配置工程并准备env
  • Windows

RT-Thread官网下载ENV工具包

  • Linux/Mac
    cd rt-thread/bsp/stm32l476-nucleo
    scons --menuconfig
    source ~/.env/env.sh
    pkgs --upgrade
  1. 生成工程(Mac/Linux下请跳过此步骤)
  • Windows MDK5
    scons --target=mdk5 -s
  1. 编译
  • Windows

使用MDK或IAR请参见对应教程。Windows下使用ENV工具已经携带GNU GCC工具链只需要在console下在bsp/stm32f411-nucleo目录下使用

    scons

即可编译成功。

  • Linux/MAC

请使用以下指令设置gcc路径

    export RTT_EXEC_PATH=[GCC路径]

而后在rt-thread/bsp/stm32f411-nucleo目录下使用

    scons

即可编译成功。

GNU GCC编译成功会在最后有如下类似信息显示

    LINK rtthread-stm32f411.elf
    arm-none-eabi-objcopy -O binary rtthread-stm32f411.elf rtthread.bin
    arm-none-eabi-size rtthread-stm32f411.elf
    text    data     bss     dec     hex filename
    55916     208    2456   58580    e4d4 rtthread-stm32f411.elf
    scons: done building targets.

并产生rtthread-stm32f411.elf、rtthread.bin文件。其中rtthread.bin为二进制固件

3. 烧写及执行

对于STM32F411-Nucleo开发板在Windows上可以直接把rtthread.bin文件拖到U盘中实现烧写。在Linux下请查找Linux下如何使用 ST-Link 的教程。

注: 如果需要使用Keil MDK来调试GNU GCC编译后的映像文件可以在编译出rt-thread/bsp/stm32f411-nucleo/rtthread-stm32f411.elf后,把这个文件改名成rtthread-stm32f4xx.axf 并放置于build目录下。然后在Keil MDK工程配置的Debug页中Run to main()选项拿掉,然后直接点击下载或调试即可进行调试(千万别再编译这个工程)。

3.1 运行结果

如果编译 & 烧写无误会在串口2上看到RT-Thread的启动logo信息
