shivanandgowdakr 0:93e3f35567a5 2
shivanandgowdakr 0:93e3f35567a5 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
shivanandgowdakr 0:93e3f35567a5 4
shivanandgowdakr 0:93e3f35567a5 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).

shivanandgowdakr 0:93e3f35567a5 7 ## Import the example application
shivanandgowdakr 0:93e3f35567a5 8
shivanandgowdakr 0:93e3f35567a5 9 From the command-line, import the example:
shivanandgowdakr 0:93e3f35567a5 10
shivanandgowdakr 0:93e3f35567a5 11 ```
shivanandgowdakr 0:93e3f35567a5 12 mbed import mbed-os-example-blinky
shivanandgowdakr 0:93e3f35567a5 13 cd mbed-os-example-blinky
shivanandgowdakr 0:93e3f35567a5 14 ```
shivanandgowdakr 0:93e3f35567a5 15
shivanandgowdakr 0:93e3f35567a5 16 ### Now compile
shivanandgowdakr 0:93e3f35567a5 17
shivanandgowdakr 0:93e3f35567a5 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:
shivanandgowdakr 0:93e3f35567a5 19
shivanandgowdakr 0:93e3f35567a5 20 ```
shivanandgowdakr 0:93e3f35567a5 21 mbed compile -m K64F -t ARM
shivanandgowdakr 0:93e3f35567a5 22 ```
shivanandgowdakr 0:93e3f35567a5 23
shivanandgowdakr 0:93e3f35567a5 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
