前置依赖（可选）

sudo apt-get install vim
sudo apt-get install cmake
sudo apt-get install libncurses-dev
sudo apt-get install libssl-dev
sudo apt-get install git

一、下载SDK和编译链

• 下载SDK

  # 创建raspberry-pi pico SDK 工作路径
  mkdir /home/hongxi/RP2040/ && cd /home/hongxi/RP2040/
  mkdir raspberry_pi_pico && cd raspberry_pi_pico
  
  git clone -b master https://github.com/raspberrypi/pico-sdk.git
  
  cd pico-sdk/
  git submodule update --init
  cd ..
  
  git clone -b master https://github.com/raspberrypi/pico-examples.git
  git clone -b master https://github.com/raspberrypi/pico-extras.git
  git clone -b master https://github.com/raspberrypi/pico-playground.git
  

• 下载交叉编译链

  mkdir toolchain && cd toolchain
  tar -vxjf gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2
  cd gcc-arm-none-eabi-10.3-2021.10
  ./bin/arm-none-eabi-gcc -v
  

• 配置

  vim ~/.bashrc 
  

  在最后追加

  #RP2040
  export PICO_SDK_PATH="/home/hongxi/RP2040/raspberry_pi_pico/pico-sdk"
  export PICO_TOOLCHAIN_PATH="/home/hongxi/RP2040/raspberry_pi_pico/toolchain/gcc-arm-none-eabi-10.3-2021.10"
  

二、编译实例工程

• 新开一个终端，进入pico-examples目录

  cd pico-examples
  mkdir build
  cd build
  cmake ..
  

• 编译blink编程

  cd pico-examples/blink
  make
  

  编译完成同级目录下生成：blink.uf2、blink.elf、blink.bin

  格式	下载方式
  .uf2	USB拖拽到flash中
  .elf	SWD下载
  .bin	flash烧写器烧写到flash中
