maclobdell 0:b0767be19223 1 # Getting started with Blinky on mbed OS
maclobdell 0:b0767be19223 2
maclobdell 0:b0767be19223 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
maclobdell 0:b0767be19223 4
maclobdell 0:b0767be19223 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
maclobdell 0:b0767be19223 6
maclobdell 0:b0767be19223 7 ## Get the example application!
maclobdell 0:b0767be19223 8
maclobdell 0:b0767be19223 9 From the command line, import the example:
maclobdell 0:b0767be19223 10
maclobdell 0:b0767be19223 11 ```
maclobdell 0:b0767be19223 12 mbed import mbed-os-example-blinky
maclobdell 0:b0767be19223 13 cd mbed-os-example-blinky
maclobdell 0:b0767be19223 14 ```
maclobdell 0:b0767be19223 15
maclobdell 0:b0767be19223 16 ### Now compile
maclobdell 0:b0767be19223 17
maclobdell 0:b0767be19223 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:
maclobdell 0:b0767be19223 19
maclobdell 0:b0767be19223 20 ```
maclobdell 0:b0767be19223 21 mbed compile -m K64F -t ARM
maclobdell 0:b0767be19223 22 ```
maclobdell 0:b0767be19223 23
maclobdell 0:b0767be19223 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
maclobdell 0:b0767be19223 25
maclobdell 0:b0767be19223 26 ```

maclobdell 0:b0767be19223 82 ## Troubleshooting
maclobdell 0:b0767be19223 83
maclobdell 0:b0767be19223 84 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
maclobdell 0:b0767be19223 85
maclobdell 0:b0767be19223 86 ```
maclobdell 0:b0767be19223 87 mbed --version
maclobdell 0:b0767be19223 88 ```
maclobdell 0:b0767be19223 89
maclobdell 0:b0767be19223 90 If not, you can update it easily:
maclobdell 0:b0767be19223 91
maclobdell 0:b0767be19223 92 ```
maclobdell 0:b0767be19223 93 pip install mbed-cli --upgrade
maclobdell 0:b0767be19223 94 ```
maclobdell 0:b0767be19223 95
maclobdell 0:b0767be19223 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.
