rozendhyan 0:135b8f0ac5d5 1 # Getting started with Blinky on mbed OS
rozendhyan 0:135b8f0ac5d5 2
rozendhyan 0:135b8f0ac5d5 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
rozendhyan 0:135b8f0ac5d5 4
rozendhyan 0:135b8f0ac5d5 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
rozendhyan 0:135b8f0ac5d5 6
rozendhyan 0:135b8f0ac5d5 7 ## Import the example application
rozendhyan 0:135b8f0ac5d5 8
rozendhyan 0:135b8f0ac5d5 9 From the command-line, import the example:
rozendhyan 0:135b8f0ac5d5 10
rozendhyan 0:135b8f0ac5d5 11 ```
rozendhyan 0:135b8f0ac5d5 12 mbed import mbed-os-example-blinky
rozendhyan 0:135b8f0ac5d5 13 cd mbed-os-example-blinky
rozendhyan 0:135b8f0ac5d5 14 ```
rozendhyan 0:135b8f0ac5d5 15
rozendhyan 0:135b8f0ac5d5 16 ### Now compile
rozendhyan 0:135b8f0ac5d5 17
rozendhyan 0:135b8f0ac5d5 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:
rozendhyan 0:135b8f0ac5d5 19
rozendhyan 0:135b8f0ac5d5 20 ```
rozendhyan 0:135b8f0ac5d5 21 mbed compile -m K64F -t ARM
rozendhyan 0:135b8f0ac5d5 22 ```
rozendhyan 0:135b8f0ac5d5 23
rozendhyan 0:135b8f0ac5d5 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
rozendhyan 0:135b8f0ac5d5 25
rozendhyan 0:135b8f0ac5d5 26 ```

rozendhyan 0:135b8f0ac5d5 55 ## Export the project to Keil MDK, and debug your application
rozendhyan 0:135b8f0ac5d5 56
rozendhyan 0:135b8f0ac5d5 57 From the command-line, run the following command:
rozendhyan 0:135b8f0ac5d5 58
rozendhyan 0:135b8f0ac5d5 59 ```
rozendhyan 0:135b8f0ac5d5 60 mbed export -m K64F -i uvision
rozendhyan 0:135b8f0ac5d5 61 ```
rozendhyan 0:135b8f0ac5d5 62
rozendhyan 0:135b8f0ac5d5 63 To debug the application:
rozendhyan 0:135b8f0ac5d5 64
rozendhyan 0:135b8f0ac5d5 65 1. Start uVision.
rozendhyan 0:135b8f0ac5d5 66 1. Import the uVision project generated earlier.
rozendhyan 0:135b8f0ac5d5 67 1. Compile your application, and generate an `.axf` file.
rozendhyan 0:135b8f0ac5d5 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).
rozendhyan 0:135b8f0ac5d5 69 1. Set breakpoints, and start a debug session.

rozendhyan 0:135b8f0ac5d5 73 ## Troubleshooting
rozendhyan 0:135b8f0ac5d5 74
rozendhyan 0:135b8f0ac5d5 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
rozendhyan 0:135b8f0ac5d5 76
rozendhyan 0:135b8f0ac5d5 77 ```
rozendhyan 0:135b8f0ac5d5 78 mbed --version
rozendhyan 0:135b8f0ac5d5 79 ```
rozendhyan 0:135b8f0ac5d5 80
rozendhyan 0:135b8f0ac5d5 81 If not, you can update it:
rozendhyan 0:135b8f0ac5d5 82
rozendhyan 0:135b8f0ac5d5 83 ```
rozendhyan 0:135b8f0ac5d5 84 pip install mbed-cli --upgrade
rozendhyan 0:135b8f0ac5d5 85 ```
rozendhyan 0:135b8f0ac5d5 86
rozendhyan 0:135b8f0ac5d5 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.
