1. 官方文档 https://docs.rust-embedded.org/book/intro/install/windows.html

第一步 安装交叉编译器

1. 我下载的是最新版本的交叉编译器和编译工具 https://developer.arm.com/-/media/Files/downloads/gnu-rm/10.3-2021.10/gcc-arm-none-eabi-10.3-2021.10-win32.exe 可能是网络不好吧，我这失败了好几次。下载过后进行安装，同样修改了路径，最后不要忘记最后一步选择“添加到环境变量”

2. 试下环境变量是否生效

安装QEMU（模拟器）

1. 网址是

新建工程

1. cargo install cargo-generate

江湖惯例出现了问题

一顿操作，芭比Q了，需要付费板。使用免费的吧

2. 使用git 创建工程

git clone https://github.com/rust-embedded/cortex-m-quickstart app
cd app

2. 添加工程信息

[package]
authors = ["{{authors}}"] # "{{authors}}" -> "John Smith"
edition = "2018"
name = "{{project-name}}" # "{{project-name}}" -> "app"
version = "0.1.0"

# ..

[[bin]]
name = "{{project-name}}" # "{{project-name}}" -> "app"
test = false
bench = false

3.编译一下
3.1 cargo build --target thumbv7m-none-eabi （M3内内核的数据）

处理报错：

PS D:\app> rustup target add thumbv7m-none-eabi
info: downloading component 'rust-std' for 'thumbv7m-none-eabi'
info: installing component 'rust-std' for 'thumbv7m-none-eabi'

3.2 cargo build --target thumbv7m-none-eabi （M3内内核的数据）编译通过了
4.安装binutil

 cargo install cargo-binutils 
//安装时真的慢
cargo readobj --bin app -- --file-headers
//查看下环境
PS D:\app> cargo readobj --bin hello -- --file-headers
    Finished dev [unoptimized + debuginfo] target(s) in 0.19s
Could not find tool: readobj
at: C:\Users\Administrator\.rustup\toolchains\stable-x86_64-pc-windows-msvc\lib\rustlib\x86_64-pc-windows-msvc\bin\llvm-readobj.exe
Consider `rustup component add llvm-tools-preview`

5. 安装rustup
   rustup component add llvm-tools-preview
   6 .执行程序
   D://qemu/qemu-system-arm.exe -cpu cortex-m3 -machine lm3s6965evb -nographic -semihosting-config enable=on,target=native -kernel target/thumbv7m-none-eabi/debug/hello
   Timer with period zero, disabling
   Hello, world!
   至此编译环境基本通了，等下下一次开发吧
