SergeyVodopyan 0:432251066eb1 1 # Getting started with Blinky on mbed OS
SergeyVodopyan 0:432251066eb1 2
SergeyVodopyan 0:432251066eb1 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
SergeyVodopyan 0:432251066eb1 4
SergeyVodopyan 0:432251066eb1 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
SergeyVodopyan 0:432251066eb1 6
SergeyVodopyan 0:432251066eb1 7 ## Import the example application
SergeyVodopyan 0:432251066eb1 8
SergeyVodopyan 0:432251066eb1 9 From the command-line, import the example:
SergeyVodopyan 0:432251066eb1 10
SergeyVodopyan 0:432251066eb1 11 ```
SergeyVodopyan 0:432251066eb1 12 mbed import mbed-os-example-blinky
SergeyVodopyan 0:432251066eb1 13 cd mbed-os-example-blinky
SergeyVodopyan 0:432251066eb1 14 ```
SergeyVodopyan 0:432251066eb1 15
SergeyVodopyan 0:432251066eb1 16 ### Now compile
SergeyVodopyan 0:432251066eb1 17
SergeyVodopyan 0:432251066eb1 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:
SergeyVodopyan 0:432251066eb1 19
SergeyVodopyan 0:432251066eb1 20 ```
SergeyVodopyan 0:432251066eb1 21 mbed compile -m K64F -t ARM
SergeyVodopyan 0:432251066eb1 22 ```
SergeyVodopyan 0:432251066eb1 23
SergeyVodopyan 0:432251066eb1 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
SergeyVodopyan 0:432251066eb1 25
SergeyVodopyan 0:432251066eb1 26 ```

SergeyVodopyan 0:432251066eb1 55 ## Export the project to Keil MDK, and debug your application
SergeyVodopyan 0:432251066eb1 56
SergeyVodopyan 0:432251066eb1 57 From the command-line, run the following command:
SergeyVodopyan 0:432251066eb1 58
SergeyVodopyan 0:432251066eb1 59 ```
SergeyVodopyan 0:432251066eb1 60 mbed export -m K64F -i uvision
SergeyVodopyan 0:432251066eb1 61 ```
SergeyVodopyan 0:432251066eb1 62
SergeyVodopyan 0:432251066eb1 63 To debug the application:
SergeyVodopyan 0:432251066eb1 64
SergeyVodopyan 0:432251066eb1 65 1. Start uVision.

SergeyVodopyan 0:432251066eb1 73 ## Troubleshooting
SergeyVodopyan 0:432251066eb1 74
SergeyVodopyan 0:432251066eb1 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
SergeyVodopyan 0:432251066eb1 76
SergeyVodopyan 0:432251066eb1 77 ```
SergeyVodopyan 0:432251066eb1 78 mbed --version
SergeyVodopyan 0:432251066eb1 79 ```
SergeyVodopyan 0:432251066eb1 80
SergeyVodopyan 0:432251066eb1 81 If not, you can update it:
SergeyVodopyan 0:432251066eb1 82
SergeyVodopyan 0:432251066eb1 83 ```
SergeyVodopyan 0:432251066eb1 84 pip install mbed-cli --upgrade
SergeyVodopyan 0:432251066eb1 85 ```
SergeyVodopyan 0:432251066eb1 86
SergeyVodopyan 0:432251066eb1 87 2. If using Keil MDK, make sure you have a license installed. [MDK-Lite](http://www.keil.com/arm/mdk.asp) has a 32 KB restriction on code size.
