randalthor 0:4232849417e1 1 # Getting started with Blinky on mbed OS
randalthor 0:4232849417e1 2
randalthor 0:4232849417e1 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
randalthor 0:4232849417e1 4
randalthor 0:4232849417e1 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
randalthor 0:4232849417e1 6
randalthor 0:4232849417e1 7 ## Import the example application
randalthor 0:4232849417e1 8
randalthor 0:4232849417e1 9 From the command-line, import the example:
randalthor 0:4232849417e1 10
randalthor 0:4232849417e1 11 ```
randalthor 0:4232849417e1 12 mbed import mbed-os-example-blinky
randalthor 0:4232849417e1 13 cd mbed-os-example-blinky
randalthor 0:4232849417e1 14 ```
randalthor 0:4232849417e1 15
randalthor 0:4232849417e1 16 ### Now compile
randalthor 0:4232849417e1 17
randalthor 0:4232849417e1 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:
randalthor 0:4232849417e1 19
randalthor 0:4232849417e1 20 ```
randalthor 0:4232849417e1 21 mbed compile -m K64F -t ARM
randalthor 0:4232849417e1 22 ```
randalthor 0:4232849417e1 23
randalthor 0:4232849417e1 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
randalthor 0:4232849417e1 25
randalthor 0:4232849417e1 26 ```

randalthor 0:4232849417e1 73 ## Troubleshooting
randalthor 0:4232849417e1 74
randalthor 0:4232849417e1 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
randalthor 0:4232849417e1 76
randalthor 0:4232849417e1 77 ```
randalthor 0:4232849417e1 78 mbed --version
randalthor 0:4232849417e1 79 ```
randalthor 0:4232849417e1 80
randalthor 0:4232849417e1 81 If not, you can update it:
randalthor 0:4232849417e1 82
randalthor 0:4232849417e1 83 ```
randalthor 0:4232849417e1 84 pip install mbed-cli --upgrade
randalthor 0:4232849417e1 85 ```
randalthor 0:4232849417e1 86
randalthor 0:4232849417e1 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.
