Tafkal 0:384a18e35fb4 1 # Getting started with Blinky on mbed OS
Tafkal 0:384a18e35fb4 2
Tafkal 0:384a18e35fb4 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
Tafkal 0:384a18e35fb4 4
Tafkal 0:384a18e35fb4 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
Tafkal 0:384a18e35fb4 6
Tafkal 0:384a18e35fb4 7 ## Import the example application
Tafkal 0:384a18e35fb4 8
Tafkal 0:384a18e35fb4 9 From the command-line, import the example:
Tafkal 0:384a18e35fb4 10
Tafkal 0:384a18e35fb4 11 ```
Tafkal 0:384a18e35fb4 12 mbed import mbed-os-example-blinky
Tafkal 0:384a18e35fb4 13 cd mbed-os-example-blinky
Tafkal 0:384a18e35fb4 14 ```
Tafkal 0:384a18e35fb4 15
Tafkal 0:384a18e35fb4 16 ### Now compile
Tafkal 0:384a18e35fb4 17
Tafkal 0:384a18e35fb4 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:
Tafkal 0:384a18e35fb4 19
Tafkal 0:384a18e35fb4 20 ```
Tafkal 0:384a18e35fb4 21 mbed compile -m K64F -t ARM
Tafkal 0:384a18e35fb4 22 ```
Tafkal 0:384a18e35fb4 23
Tafkal 0:384a18e35fb4 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
Tafkal 0:384a18e35fb4 25

Tafkal 0:384a18e35fb4 55 ## Export the project to Keil MDK, and debug your application
Tafkal 0:384a18e35fb4 56
Tafkal 0:384a18e35fb4 57 From the command-line, run the following command:
Tafkal 0:384a18e35fb4 58
Tafkal 0:384a18e35fb4 59 ```
Tafkal 0:384a18e35fb4 60 mbed export -m K64F -i uvision
Tafkal 0:384a18e35fb4 61 ```
Tafkal 0:384a18e35fb4 62
Tafkal 0:384a18e35fb4 63 To debug the application:

Tafkal 0:384a18e35fb4 73 ## Troubleshooting
Tafkal 0:384a18e35fb4 74
Tafkal 0:384a18e35fb4 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
Tafkal 0:384a18e35fb4 76
Tafkal 0:384a18e35fb4 77 ```
Tafkal 0:384a18e35fb4 78 mbed --version
Tafkal 0:384a18e35fb4 79 ```
Tafkal 0:384a18e35fb4 80
Tafkal 0:384a18e35fb4 81 If not, you can update it:
Tafkal 0:384a18e35fb4 82
Tafkal 0:384a18e35fb4 83 ```
Tafkal 0:384a18e35fb4 84 pip install mbed-cli --upgrade
Tafkal 0:384a18e35fb4 85 ```
Tafkal 0:384a18e35fb4 86
Tafkal 0:384a18e35fb4 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.
