RGurav 0:889636b54b07 1 # Getting started with Blinky on mbed OS
RGurav 0:889636b54b07 2
RGurav 0:889636b54b07 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
RGurav 0:889636b54b07 4
RGurav 0:889636b54b07 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
RGurav 0:889636b54b07 6
RGurav 0:889636b54b07 7 ## Import the example application
RGurav 0:889636b54b07 8
RGurav 0:889636b54b07 9 From the command-line, import the example:
RGurav 0:889636b54b07 10
RGurav 0:889636b54b07 11 ```
RGurav 0:889636b54b07 12 mbed import mbed-os-example-blinky
RGurav 0:889636b54b07 13 cd mbed-os-example-blinky
RGurav 0:889636b54b07 14 ```
RGurav 0:889636b54b07 15
RGurav 0:889636b54b07 16 ### Now compile
RGurav 0:889636b54b07 17
RGurav 0:889636b54b07 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:
RGurav 0:889636b54b07 19
RGurav 0:889636b54b07 20 ```
RGurav 0:889636b54b07 21 mbed compile -m K64F -t ARM
RGurav 0:889636b54b07 22 ```
RGurav 0:889636b54b07 23
RGurav 0:889636b54b07 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
