| gidiana | 12:a34ecb37c03f | 2 | |
| gidiana | 12:a34ecb37c03f | 3 | This guide reviews the steps required to get Blinky with the addition of dynamic OS statistics working on an Mbed OS platform. |
| gidiana | 12:a34ecb37c03f | 4 | |
| gidiana | 12:a34ecb37c03f | 5 | Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli). |
| gidiana | 12:a34ecb37c03f | 6 | |
| gidiana | 12:a34ecb37c03f | 7 | ## Import the example application |
| gidiana | 12:a34ecb37c03f | 8 | |
| gidiana | 12:a34ecb37c03f | 9 | From the command-line, import the example: |
| gidiana | 12:a34ecb37c03f | 10 | |
| gidiana | 12:a34ecb37c03f | 11 | ``` |
| gidiana | 12:a34ecb37c03f | 12 | mbed import mbed-os-example-blinky |
| gidiana | 12:a34ecb37c03f | 13 | cd mbed-os-example-blinky |
| gidiana | 12:a34ecb37c03f | 14 | ``` |
| gidiana | 12:a34ecb37c03f | 15 | |
| gidiana | 12:a34ecb37c03f | 16 | ### Now compile |
| gidiana | 12:a34ecb37c03f | 17 | |
| gidiana | 12:a34ecb37c03f | 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: |
| gidiana | 12:a34ecb37c03f | 19 | |
| gidiana | 12:a34ecb37c03f | 20 | ``` |
| gidiana | 12:a34ecb37c03f | 21 | mbed compile -m K64F -t ARM |
| gidiana | 12:a34ecb37c03f | 22 | ``` |
| gidiana | 12:a34ecb37c03f | 23 | |
| gidiana | 12:a34ecb37c03f | 24 | Your PC may take a few minutes to compile your code. At the end, you see the following result: |
| gidiana | 12:a34ecb37c03f | 25 | |
