michaelVisimid 0:fcb2f7f70518 1 # Getting started with Blinky on mbed OS
michaelVisimid 0:fcb2f7f70518 2
michaelVisimid 0:fcb2f7f70518 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
michaelVisimid 0:fcb2f7f70518 4
michaelVisimid 0:fcb2f7f70518 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
michaelVisimid 0:fcb2f7f70518 6
michaelVisimid 0:fcb2f7f70518 7 ## Import the example application
michaelVisimid 0:fcb2f7f70518 8
michaelVisimid 0:fcb2f7f70518 9 From the command-line, import the example:
michaelVisimid 0:fcb2f7f70518 10
michaelVisimid 0:fcb2f7f70518 11 ```
michaelVisimid 0:fcb2f7f70518 12 mbed import mbed-os-example-blinky
michaelVisimid 0:fcb2f7f70518 13 cd mbed-os-example-blinky
michaelVisimid 0:fcb2f7f70518 14 ```
michaelVisimid 0:fcb2f7f70518 15
michaelVisimid 0:fcb2f7f70518 16 ### Now compile
michaelVisimid 0:fcb2f7f70518 17
michaelVisimid 0:fcb2f7f70518 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:
michaelVisimid 0:fcb2f7f70518 19
michaelVisimid 0:fcb2f7f70518 20 ```
michaelVisimid 0:fcb2f7f70518 21 mbed compile -m K64F -t ARM
michaelVisimid 0:fcb2f7f70518 22 ```
michaelVisimid 0:fcb2f7f70518 23
michaelVisimid 0:fcb2f7f70518 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
michaelVisimid 0:fcb2f7f70518 25

michaelVisimid 0:fcb2f7f70518 73 ## Troubleshooting
michaelVisimid 0:fcb2f7f70518 74
michaelVisimid 0:fcb2f7f70518 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
michaelVisimid 0:fcb2f7f70518 76
michaelVisimid 0:fcb2f7f70518 77 ```
michaelVisimid 0:fcb2f7f70518 78 mbed --version
michaelVisimid 0:fcb2f7f70518 79 ```
michaelVisimid 0:fcb2f7f70518 80
michaelVisimid 0:fcb2f7f70518 81 If not, you can update it:
michaelVisimid 0:fcb2f7f70518 82
michaelVisimid 0:fcb2f7f70518 83 ```
michaelVisimid 0:fcb2f7f70518 84 pip install mbed-cli --upgrade
michaelVisimid 0:fcb2f7f70518 85 ```
michaelVisimid 0:fcb2f7f70518 86
michaelVisimid 0:fcb2f7f70518 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.
