noutram 0:e48f4ddb9393 1 # Getting started with Blinky on mbed OS
noutram 0:e48f4ddb9393 2
noutram 0:e48f4ddb9393 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
noutram 0:e48f4ddb9393 4
noutram 0:e48f4ddb9393 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
noutram 0:e48f4ddb9393 6
noutram 0:e48f4ddb9393 7 ## Import the example application
noutram 0:e48f4ddb9393 8
noutram 0:e48f4ddb9393 9 From the command-line, import the example:
noutram 0:e48f4ddb9393 10
noutram 0:e48f4ddb9393 11 ```
noutram 0:e48f4ddb9393 12 mbed import mbed-os-example-blinky
noutram 0:e48f4ddb9393 13 cd mbed-os-example-blinky
noutram 0:e48f4ddb9393 14 ```
noutram 0:e48f4ddb9393 15
noutram 0:e48f4ddb9393 16 ### Now compile
noutram 0:e48f4ddb9393 17
noutram 0:e48f4ddb9393 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:
noutram 0:e48f4ddb9393 19
noutram 0:e48f4ddb9393 20 ```
noutram 0:e48f4ddb9393 21 mbed compile -m K64F -t ARM
noutram 0:e48f4ddb9393 22 ```
noutram 0:e48f4ddb9393 23
noutram 0:e48f4ddb9393 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
noutram 0:e48f4ddb9393 25
noutram 0:e48f4ddb9393 26 ```

noutram 0:e48f4ddb9393 47 ### Program your board
noutram 0:e48f4ddb9393 48
noutram 0:e48f4ddb9393 49 1. Connect your mbed device to the computer over USB.
noutram 0:e48f4ddb9393 50 1. Copy the binary file to the mbed device.
noutram 0:e48f4ddb9393 51 1. Press the reset button to start the program.
noutram 0:e48f4ddb9393 52
noutram 0:e48f4ddb9393 53 The LED on your platform turns on and off.
noutram 0:e48f4ddb9393 54
noutram 0:e48f4ddb9393 55 ## Export the project to Keil MDK, and debug your application
noutram 0:e48f4ddb9393 56
noutram 0:e48f4ddb9393 57 From the command-line, run the following command:
noutram 0:e48f4ddb9393 58
noutram 0:e48f4ddb9393 59 ```
noutram 0:e48f4ddb9393 60 mbed export -m K64F -i uvision
noutram 0:e48f4ddb9393 61 ```
noutram 0:e48f4ddb9393 62
noutram 0:e48f4ddb9393 63 To debug the application:
noutram 0:e48f4ddb9393 64
noutram 0:e48f4ddb9393 65 1. Start uVision.
noutram 0:e48f4ddb9393 66 1. Import the uVision project generated earlier.
noutram 0:e48f4ddb9393 67 1. Compile your application, and generate an `.axf` file.
noutram 0:e48f4ddb9393 68 1. Make sure uVision is configured to debug over CMSIS-DAP (From the Project menu > Options for Target '...' > Debug tab > Use CMSIS-DAP Debugger).
noutram 0:e48f4ddb9393 69 1. Set breakpoints, and start a debug session.

noutram 0:e48f4ddb9393 73 ## Troubleshooting
noutram 0:e48f4ddb9393 74
noutram 0:e48f4ddb9393 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
noutram 0:e48f4ddb9393 76
noutram 0:e48f4ddb9393 77 ```
noutram 0:e48f4ddb9393 78 mbed --version
noutram 0:e48f4ddb9393 79 ```
noutram 0:e48f4ddb9393 80
noutram 0:e48f4ddb9393 81 If not, you can update it:
noutram 0:e48f4ddb9393 82
noutram 0:e48f4ddb9393 83 ```
noutram 0:e48f4ddb9393 84 pip install mbed-cli --upgrade
noutram 0:e48f4ddb9393 85 ```
noutram 0:e48f4ddb9393 86
noutram 0:e48f4ddb9393 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.
