A Zephyr RTOS codespace based on devcontainer

Usage

# Make sure the build is clean
user@480c36b20b00:/workdir$ rm -rf /workdir/app/build

# Build the app
user@480c36b20b00:/workdir$ west build /workdir/app -d /workdir/app/build -p auto -b nucleo_f767zi

# Flash the app
user@480c36b20b00:/workdir$ west flash -d /workdir/app/build

# Debug the app with gdb
user@480c36b20b00:/workdir$ west debug --build-dir app/build/

Windows 11

Install docker on WSL2 following this link https://learn.microsoft.com/en-us/windows/wsl/tutorials/wsl-containers

Limitation

ZEPHYR_BASE environment variable is hard coded in the docker image

✅ ToDo

• Build an STM32 app

• Flash app using openocd

• Debug app using vscode cortex-debug

• Restructure workspace to be compatible with the hard coded ZEPHYR_BASE path
