mijimy 0:819b4e0e0ae6 1 # Getting started with Blinky on mbed OS
mijimy 0:819b4e0e0ae6 2
mijimy 0:819b4e0e0ae6 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
mijimy 0:819b4e0e0ae6 4
mijimy 0:819b4e0e0ae6 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
mijimy 0:819b4e0e0ae6 6
mijimy 0:819b4e0e0ae6 7 ## Import the example application
mijimy 0:819b4e0e0ae6 8
mijimy 0:819b4e0e0ae6 9 From the command-line, import the example:
mijimy 0:819b4e0e0ae6 10
mijimy 0:819b4e0e0ae6 11 ```
mijimy 0:819b4e0e0ae6 12 mbed import mbed-os-example-blinky
mijimy 0:819b4e0e0ae6 13 cd mbed-os-example-blinky
mijimy 0:819b4e0e0ae6 14 ```
mijimy 0:819b4e0e0ae6 15
mijimy 0:819b4e0e0ae6 16 ### Now compile
mijimy 0:819b4e0e0ae6 17
mijimy 0:819b4e0e0ae6 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:
mijimy 0:819b4e0e0ae6 19
mijimy 0:819b4e0e0ae6 20 ```
mijimy 0:819b4e0e0ae6 21 mbed compile -m K64F -t ARM
mijimy 0:819b4e0e0ae6 22 ```
mijimy 0:819b4e0e0ae6 23
mijimy 0:819b4e0e0ae6 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
mijimy 0:819b4e0e0ae6 25
mijimy 0:819b4e0e0ae6 26 ```

mijimy 0:819b4e0e0ae6 47 ### Program your board
mijimy 0:819b4e0e0ae6 48
mijimy 0:819b4e0e0ae6 49 1. Connect your mbed device to the computer over USB.
mijimy 0:819b4e0e0ae6 50 1. Copy the binary file to the mbed device.
mijimy 0:819b4e0e0ae6 51 1. Press the reset button to start the program.
mijimy 0:819b4e0e0ae6 52
mijimy 0:819b4e0e0ae6 53 The LED on your platform turns on and off.
mijimy 0:819b4e0e0ae6 54
mijimy 0:819b4e0e0ae6 55 ## Export the project to Keil MDK, and debug your application
mijimy 0:819b4e0e0ae6 56
mijimy 0:819b4e0e0ae6 57 From the command-line, run the following command:
mijimy 0:819b4e0e0ae6 58
mijimy 0:819b4e0e0ae6 59 ```
mijimy 0:819b4e0e0ae6 60 mbed export -m K64F -i uvision
mijimy 0:819b4e0e0ae6 61 ```
mijimy 0:819b4e0e0ae6 62
mijimy 0:819b4e0e0ae6 63 To debug the application:
mijimy 0:819b4e0e0ae6 64
mijimy 0:819b4e0e0ae6 65 1. Start uVision.
mijimy 0:819b4e0e0ae6 66 1. Import the uVision project generated earlier.
mijimy 0:819b4e0e0ae6 67 1. Compile your application, and generate an `.axf` file.
mijimy 0:819b4e0e0ae6 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).
mijimy 0:819b4e0e0ae6 69 1. Set breakpoints, and start a debug session.

mijimy 0:819b4e0e0ae6 73 ## Troubleshooting
mijimy 0:819b4e0e0ae6 74
mijimy 0:819b4e0e0ae6 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
mijimy 0:819b4e0e0ae6 76
mijimy 0:819b4e0e0ae6 77 ```
mijimy 0:819b4e0e0ae6 78 mbed --version
mijimy 0:819b4e0e0ae6 79 ```
mijimy 0:819b4e0e0ae6 80
mijimy 0:819b4e0e0ae6 81 If not, you can update it:
mijimy 0:819b4e0e0ae6 82
mijimy 0:819b4e0e0ae6 83 ```
mijimy 0:819b4e0e0ae6 84 pip install mbed-cli --upgrade
mijimy 0:819b4e0e0ae6 85 ```
mijimy 0:819b4e0e0ae6 86
mijimy 0:819b4e0e0ae6 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.
