This guide reviews the steps required to get Blinky working on an mbed OS platform.
Please install mbed CLI.
From the command-line, import the example:
mbed import mbed-os-example-blinky
cd mbed-os-example-blinky
Invoke mbed compile
, and specify the name of your platform and your favorite toolchain (GCC_ARM
, ARM
, IAR
). For example, for the ARM Compiler 5:
mbed compile -m K64F -t ARM
Your PC may take a few minutes to compile your code. At the end, you see the following result:

- Connect your mbed device to the computer over USB.
- Copy the binary file to the mbed device.
- Press the reset button to start the program.
The LED on your platform turns on and off.
From the command-line, run the following command:
mbed export -m K64F -i uvision
To debug the application:
- Start uVision.
- Import the uVision project generated earlier.
- Compile your application, and generate an
.axf
file. - Make sure uVision is configured to debug over CMSIS-DAP (From the Project menu > Options for Target '...' > Debug tab > Use CMSIS-DAP Debugger).
- Set breakpoints, and start a debug session.
If you have problems, you can review the documentation for suggestions on what could be wrong and how to fix it.
