Valoni 0:c3dab0101dea 1 # Getting started with Blinky on mbed OS
Valoni 0:c3dab0101dea 2
Valoni 0:c3dab0101dea 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
Valoni 0:c3dab0101dea 4
Valoni 0:c3dab0101dea 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
Valoni 0:c3dab0101dea 6
Valoni 0:c3dab0101dea 7 ## Import the example application
Valoni 0:c3dab0101dea 8
Valoni 0:c3dab0101dea 9 From the command-line, import the example:
Valoni 0:c3dab0101dea 10
Valoni 0:c3dab0101dea 11 ```
Valoni 0:c3dab0101dea 12 mbed import mbed-os-example-blinky
Valoni 0:c3dab0101dea 13 cd mbed-os-example-blinky
Valoni 0:c3dab0101dea 14 ```
Valoni 0:c3dab0101dea 15
Valoni 0:c3dab0101dea 16 ### Now compile
Valoni 0:c3dab0101dea 17
Valoni 0:c3dab0101dea 18 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:
Valoni 0:c3dab0101dea 19
Valoni 0:c3dab0101dea 20 ```
Valoni 0:c3dab0101dea 21 mbed compile -m K64F -t ARM
Valoni 0:c3dab0101dea 22 ```
Valoni 0:c3dab0101dea 23
Valoni 0:c3dab0101dea 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
Valoni 0:c3dab0101dea 25
Valoni 0:c3dab0101dea 26 ```

Valoni 0:c3dab0101dea 47 ### Program your board
Valoni 0:c3dab0101dea 48
Valoni 0:c3dab0101dea 49 1. Connect your mbed device to the computer over USB.
Valoni 0:c3dab0101dea 50 1. Copy the binary file to the mbed device.
Valoni 0:c3dab0101dea 51 1. Press the reset button to start the program.
Valoni 0:c3dab0101dea 52
Valoni 0:c3dab0101dea 53 The LED on your platform turns on and off.
Valoni 0:c3dab0101dea 54
Valoni 0:c3dab0101dea 55 ## Export the project to Keil MDK, and debug your application
Valoni 0:c3dab0101dea 56
Valoni 0:c3dab0101dea 57 From the command-line, run the following command:
Valoni 0:c3dab0101dea 58
Valoni 0:c3dab0101dea 59 ```
Valoni 0:c3dab0101dea 60 mbed export -m K64F -i uvision
Valoni 0:c3dab0101dea 61 ```
Valoni 0:c3dab0101dea 62
Valoni 0:c3dab0101dea 63 To debug the application:
Valoni 0:c3dab0101dea 64
Valoni 0:c3dab0101dea 65 1. Start uVision.
Valoni 0:c3dab0101dea 66 1. Import the uVision project generated earlier.
Valoni 0:c3dab0101dea 67 1. Compile your application, and generate an `.axf` file.
Valoni 0:c3dab0101dea 68 1. Make sure uVision is configured to debug over CMSIS-DAP (From the Project menu > Options for Target '...' > Debug tab > Use CMSIS-DAP Debugger).
Valoni 0:c3dab0101dea 69 1. Set breakpoints, and start a debug session.

Valoni 0:c3dab0101dea 73 ## Troubleshooting
Valoni 0:c3dab0101dea 74
Valoni 0:c3dab0101dea 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
Valoni 0:c3dab0101dea 76
Valoni 0:c3dab0101dea 77 ```
Valoni 0:c3dab0101dea 78 mbed --version
Valoni 0:c3dab0101dea 79 ```
Valoni 0:c3dab0101dea 80
Valoni 0:c3dab0101dea 81 If not, you can update it:
Valoni 0:c3dab0101dea 82
Valoni 0:c3dab0101dea 83 ```
Valoni 0:c3dab0101dea 84 pip install mbed-cli --upgrade
Valoni 0:c3dab0101dea 85 ```
Valoni 0:c3dab0101dea 86
Valoni 0:c3dab0101dea 87 2. If using Keil MDK, make sure you have a license installed. [MDK-Lite](http://www.keil.com/arm/mdk.asp) has a 32 KB restriction on code size.
