Compiling the code

  1. When Mbed CLI is installed, get the code for the Mbed OS full profile or bare metal profile.

    Open a command-line shell.

    For the full profile, enter:

    $ mbed import https://github.com/ARMmbed/mbed-os-example-blinky
    $ cd mbed-os-example-blinky

    For the bare metal profile, enter:

    $ mbed import https://github.com/ARMmbed/mbed-os-example-blinky-baremetal
    $ cd mbed-os-example-blinky-baremetal

    The rest of the workflow is identical for both profiles.

  2. Compile and program your board:

    Invoke mbed compile, and specify the name of your build target and your installed toolchain (GCC_ARM, ARM, IAR). For example, for the K64F board and ARM toolchain:

    $ mbed compile --target K64F --toolchain ARM --flash

    The --flash argument automatically flashes the compiled program onto your board if it is connected to your computer.

    Tip: You can get the name of the board plugged into your computer by running mbed detect, and you can get a full list of supported toolchains and targets by running the mbed compile --supported command.

    Note: To build with the Mbed OS bare metal profile, add "requires": ["bare-metal"] to the mbed_app.json file:

           "requires": ["bare-metal"],
           "target_overrides": {
               "*": {
  3. Press the board's reset button. The LED blinks.
