5. WSL2 嵌入式工程-Zephyr篇

雖然官網說 WSL因爲 裝置無法燒錄不建議用 WSL，但我們可以用 usbipd連接 USB 裝置了，剩下的工作同 Ubuntu，不必再為 Windows安裝奇奇怪怪的東西了。。。

22.04 前的 Ubuntu 要添加 apt 源：

wget https：//apt.kitware.com/kitware-archive.sh
sudo bash kitware-archive.sh

編譯環境：

sudo apt-get install --no-install-recommends git cmake ninja-build gperf \
  ccache dfu-util device-tree-compiler wget \
  python3-dev python3-pip python3-setuptools python3-tk python3-wheel xz-utils file libpython3.8-dev \
  make gcc gcc-multilib g++-multilib libsdl2-dev libmagic1

安裝 cmake：

sudo snap install cmake --classic

取得 zephyrSDK：

(current stable version： v0.15.2)： 我放在 ~/.local 下（參考官網建議notes）。

cd ~/.local
# (see notes)
wget https：//github.com/zephyrproject-rtos/sdk-ng/releases/download/v0.15.2/zephyr-sdk-0.15.2_linux-x86_64.tar.gz
wget -O - https：//github.com/zephyrproject-rtos/sdk-ng/releases/download/v0.15.2/sha256.sum | shasum --check --ignore-missing

tar xvf zephyr-sdk-0.15.2_linux-x86_64.tar.gz

cd zephyr-sdk-0.15.2
./setup.sh
# If you want to uninstall the SDK， remove the directory where you installed it。If you relocate the SDK directory， you need to re-run the setup script.

It is recommended to extract the Zephyr SDK bundle at one of the following locations：

• $HOME
• $HOME/.local
• $HOME/.local/opt
• $HOME/bin
• /opt
• /usr/local

The Zephyr SDK bundle archive contains the zephyr-sdk-0.15.2 directory and，when extracted under $HOME，the resulting installation path will be `$HOME/zephyr-sdk-0.15.2.

If you install the Zephyr SDK outside any of these locations，you must register the Zephyr SDK in the CMake package registry by running the setup script，or set ZEPHYR_SDK_INSTALL_DIR to point to the Zephyr SDK installation directory.

安裝 West與 Zephyr Source Code：

1. Install west，and make sure ~/.local/bin is on your PATH environment variable：

   pip3 install --user -U west
   echo 'export PATH=~/.local/bin："$PATH"' >> ~/.bashrc
   source ~/.bashrc
   

2. Get the Zephyr source code：

   west init ~/zephyrproject
   cd ~/zephyrproject
   west update
   

3. Export a Zephyr CMake package。This allows CMake to automatically load boilerplate code required for building Zephyr applications.

   west zephyr-export
   

4. Zephyr’s scripts/requirements.txt file declares additional Python dependencies。Install them with pip3.

   pip3 install --user -r ~/zephyrproject/zephyr/scripts/requirements.txt
