khayakawa 0:1a04fda5faa3 1 # Getting started with Blinky on mbed OS
khayakawa 0:1a04fda5faa3 2
khayakawa 0:1a04fda5faa3 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
khayakawa 0:1a04fda5faa3 4
khayakawa 0:1a04fda5faa3 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
khayakawa 0:1a04fda5faa3 6
khayakawa 0:1a04fda5faa3 7 ## Import the example application
khayakawa 0:1a04fda5faa3 8
khayakawa 0:1a04fda5faa3 9 From the command-line, import the example:
khayakawa 0:1a04fda5faa3 10
khayakawa 0:1a04fda5faa3 11 ```
khayakawa 0:1a04fda5faa3 12 mbed import mbed-os-example-blinky
khayakawa 0:1a04fda5faa3 13 cd mbed-os-example-blinky
khayakawa 0:1a04fda5faa3 14 ```
khayakawa 0:1a04fda5faa3 15
khayakawa 0:1a04fda5faa3 16 ### Now compile
khayakawa 0:1a04fda5faa3 17
khayakawa 0:1a04fda5faa3 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:
khayakawa 0:1a04fda5faa3 19
khayakawa 0:1a04fda5faa3 20 ```
khayakawa 0:1a04fda5faa3 21 mbed compile -m K64F -t ARM
khayakawa 0:1a04fda5faa3 22 ```
khayakawa 0:1a04fda5faa3 23
khayakawa 0:1a04fda5faa3 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
khayakawa 0:1a04fda5faa3 25

khayakawa 0:1a04fda5faa3 47 ### Program your board
khayakawa 0:1a04fda5faa3 48
khayakawa 0:1a04fda5faa3 49 1. Connect your mbed device to the computer over USB.
khayakawa 0:1a04fda5faa3 50 1. Copy the binary file to the mbed device.
khayakawa 0:1a04fda5faa3 51 1. Press the reset button to start the program.
khayakawa 0:1a04fda5faa3 52
khayakawa 0:1a04fda5faa3 53 The LED on your platform turns on and off.
khayakawa 0:1a04fda5faa3 54
khayakawa 0:1a04fda5faa3 55 ## Export the project to Keil MDK, and debug your application
khayakawa 0:1a04fda5faa3 56
khayakawa 0:1a04fda5faa3 57 From the command-line, run the following command:
khayakawa 0:1a04fda5faa3 58
khayakawa 0:1a04fda5faa3 59 ```
khayakawa 0:1a04fda5faa3 60 mbed export -m K64F -i uvision
khayakawa 0:1a04fda5faa3 61 ```
khayakawa 0:1a04fda5faa3 62
khayakawa 0:1a04fda5faa3 63 To debug the application:
khayakawa 0:1a04fda5faa3 64
khayakawa 0:1a04fda5faa3 65 1. Start uVision.
khayakawa 0:1a04fda5faa3 66 1. Import the uVision project generated earlier.
khayakawa 0:1a04fda5faa3 67 1. Compile your application, and generate an `.axf` file.
khayakawa 0:1a04fda5faa3 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).
khayakawa 0:1a04fda5faa3 69 1. Set breakpoints, and start a debug session.

khayakawa 0:1a04fda5faa3 73 ## Troubleshooting
khayakawa 0:1a04fda5faa3 74
khayakawa 0:1a04fda5faa3 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
khayakawa 0:1a04fda5faa3 76
khayakawa 0:1a04fda5faa3 77 ```
khayakawa 0:1a04fda5faa3 78 mbed --version
khayakawa 0:1a04fda5faa3 79 ```
khayakawa 0:1a04fda5faa3 80
khayakawa 0:1a04fda5faa3 81 If not, you can update it:
khayakawa 0:1a04fda5faa3 82
khayakawa 0:1a04fda5faa3 83 ```
khayakawa 0:1a04fda5faa3 84 pip install mbed-cli --upgrade
khayakawa 0:1a04fda5faa3 85 ```
khayakawa 0:1a04fda5faa3 86
khayakawa 0:1a04fda5faa3 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.
