udagawa 0:41304d545e93 1 # Getting started with Blinky on mbed OS
udagawa 0:41304d545e93 2
udagawa 0:41304d545e93 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
udagawa 0:41304d545e93 4
udagawa 0:41304d545e93 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
udagawa 0:41304d545e93 6
udagawa 0:41304d545e93 7 ## Import the example application
udagawa 0:41304d545e93 8
udagawa 0:41304d545e93 9 From the command-line, import the example:
udagawa 0:41304d545e93 10
udagawa 0:41304d545e93 11 ```
udagawa 0:41304d545e93 12 mbed import mbed-os-example-blinky
udagawa 0:41304d545e93 13 cd mbed-os-example-blinky
udagawa 0:41304d545e93 14 ```
udagawa 0:41304d545e93 15
udagawa 0:41304d545e93 16 ### Now compile
udagawa 0:41304d545e93 17
udagawa 0:41304d545e93 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:
udagawa 0:41304d545e93 19
udagawa 0:41304d545e93 20 ```
udagawa 0:41304d545e93 21 mbed compile -m K64F -t ARM
udagawa 0:41304d545e93 22 ```
udagawa 0:41304d545e93 23
udagawa 0:41304d545e93 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
udagawa 0:41304d545e93 25
udagawa 0:41304d545e93 26 ```

udagawa 0:41304d545e93 73 ## Troubleshooting
udagawa 0:41304d545e93 74
udagawa 0:41304d545e93 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
udagawa 0:41304d545e93 76
udagawa 0:41304d545e93 77 ```
udagawa 0:41304d545e93 78 mbed --version
udagawa 0:41304d545e93 79 ```
udagawa 0:41304d545e93 80
udagawa 0:41304d545e93 81 If not, you can update it:
udagawa 0:41304d545e93 82
udagawa 0:41304d545e93 83 ```
udagawa 0:41304d545e93 84 pip install mbed-cli --upgrade
udagawa 0:41304d545e93 85 ```
udagawa 0:41304d545e93 86
udagawa 0:41304d545e93 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.
