AustinKim 0:37121f302ff1 2
AustinKim 0:37121f302ff1 3 This guide reviews the steps required to get Blinky with the addition of dynamic OS statistics working on an Mbed OS platform. (Note: To see a rendered example you can import into the Arm Online Compiler, please see our [quick start](https://os.mbed.com/docs/mbed-os/latest/quick-start/online-with-the-online-compiler.html#importing-the-code).)
AustinKim 0:37121f302ff1 4
AustinKim 0:37121f302ff1 5 Please install [Mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
AustinKim 0:37121f302ff1 6
AustinKim 0:37121f302ff1 7 ## Import the example application
AustinKim 0:37121f302ff1 8
AustinKim 0:37121f302ff1 9 From the command-line, import the example:
AustinKim 0:37121f302ff1 10
AustinKim 0:37121f302ff1 11 ```
AustinKim 0:37121f302ff1 12 mbed import mbed-os-example-blinky
AustinKim 0:37121f302ff1 13 cd mbed-os-example-blinky
AustinKim 0:37121f302ff1 14 ```
AustinKim 0:37121f302ff1 15
AustinKim 0:37121f302ff1 16 ### Now compile
AustinKim 0:37121f302ff1 17
AustinKim 0:37121f302ff1 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:
AustinKim 0:37121f302ff1 19
AustinKim 0:37121f302ff1 20 ```
AustinKim 0:37121f302ff1 21 mbed compile -m K64F -t ARM
AustinKim 0:37121f302ff1 22 ```
AustinKim 0:37121f302ff1 23
AustinKim 0:37121f302ff1 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
AustinKim 0:37121f302ff1 25
AustinKim 0:37121f302ff1 26 ```

AustinKim 0:37121f302ff1 30 ```
AustinKim 0:37121f302ff1 31
AustinKim 0:37121f302ff1 32 ### Program your board
AustinKim 0:37121f302ff1 33
AustinKim 0:37121f302ff1 34 1. Connect your Mbed device to the computer over USB.
AustinKim 0:37121f302ff1 35 1. Copy the binary file to the Mbed device.
AustinKim 0:37121f302ff1 36 1. Press the reset button to start the program.
AustinKim 0:37121f302ff1 37
AustinKim 0:37121f302ff1 38 The LED on your platform turns on and off. The main thread will additionally take a snapshot of the device's runtime statistics and display it over serial to your PC. The snapshot includes:
