eddienuel 0:bd3942174be3 1 # Getting started with Blinky on mbed OS
eddienuel 0:bd3942174be3 2
eddienuel 0:bd3942174be3 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
eddienuel 0:bd3942174be3 4
eddienuel 0:bd3942174be3 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
eddienuel 0:bd3942174be3 6
eddienuel 0:bd3942174be3 7 ## Get the example application!
eddienuel 0:bd3942174be3 8
eddienuel 0:bd3942174be3 9 From the command line, import the example:
eddienuel 0:bd3942174be3 10
eddienuel 0:bd3942174be3 11 ```
eddienuel 0:bd3942174be3 12 mbed import mbed-os-example-blinky
eddienuel 0:bd3942174be3 13 cd mbed-os-example-blinky
eddienuel 0:bd3942174be3 14 ```
eddienuel 0:bd3942174be3 15
eddienuel 0:bd3942174be3 16 ### Now compile
eddienuel 0:bd3942174be3 17
eddienuel 0:bd3942174be3 18 Invoke `mbed compile` specifying the name of your platform and your favorite toolchain (`GCC_ARM`, `ARM`, `IAR`). For example, for the ARM Compiler 5:
eddienuel 0:bd3942174be3 19
eddienuel 0:bd3942174be3 20 ```
eddienuel 0:bd3942174be3 21 mbed compile -m K64F -t ARM
eddienuel 0:bd3942174be3 22 ```
eddienuel 0:bd3942174be3 23
eddienuel 0:bd3942174be3 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
eddienuel 0:bd3942174be3 25
eddienuel 0:bd3942174be3 26 ```

eddienuel 0:bd3942174be3 82 ## Troubleshooting
eddienuel 0:bd3942174be3 83
eddienuel 0:bd3942174be3 84 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
eddienuel 0:bd3942174be3 85
eddienuel 0:bd3942174be3 86 ```
eddienuel 0:bd3942174be3 87 mbed --version
eddienuel 0:bd3942174be3 88 ```
eddienuel 0:bd3942174be3 89
eddienuel 0:bd3942174be3 90 If not, you can update it easily:
eddienuel 0:bd3942174be3 91
eddienuel 0:bd3942174be3 92 ```
eddienuel 0:bd3942174be3 93 pip install mbed-cli --upgrade
eddienuel 0:bd3942174be3 94 ```
eddienuel 0:bd3942174be3 95
eddienuel 0:bd3942174be3 96 2. If using Keil MDK, make sure you have a license installed. [MDK-Lite](http://www.keil.com/arm/mdk.asp) has a 32KB restriction on code size.
