pratiksk 0:70cb5a6a3a4c 1 # Getting started with Blinky on mbed OS
pratiksk 0:70cb5a6a3a4c 2
pratiksk 0:70cb5a6a3a4c 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
pratiksk 0:70cb5a6a3a4c 4
pratiksk 0:70cb5a6a3a4c 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
pratiksk 0:70cb5a6a3a4c 6
pratiksk 0:70cb5a6a3a4c 7 ## Import the example application
pratiksk 0:70cb5a6a3a4c 8
pratiksk 0:70cb5a6a3a4c 9 From the command-line, import the example:
pratiksk 0:70cb5a6a3a4c 10
pratiksk 0:70cb5a6a3a4c 11 ```
pratiksk 0:70cb5a6a3a4c 12 mbed import mbed-os-example-blinky
pratiksk 0:70cb5a6a3a4c 13 cd mbed-os-example-blinky
pratiksk 0:70cb5a6a3a4c 14 ```
pratiksk 0:70cb5a6a3a4c 15
pratiksk 0:70cb5a6a3a4c 16 ### Now compile
pratiksk 0:70cb5a6a3a4c 17
pratiksk 0:70cb5a6a3a4c 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:
pratiksk 0:70cb5a6a3a4c 19
pratiksk 0:70cb5a6a3a4c 20 ```
pratiksk 0:70cb5a6a3a4c 21 mbed compile -m K64F -t ARM
pratiksk 0:70cb5a6a3a4c 22 ```
pratiksk 0:70cb5a6a3a4c 23
pratiksk 0:70cb5a6a3a4c 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
pratiksk 0:70cb5a6a3a4c 25
pratiksk 0:70cb5a6a3a4c 26 ```

pratiksk 0:70cb5a6a3a4c 47 ### Program your board
pratiksk 0:70cb5a6a3a4c 48
pratiksk 0:70cb5a6a3a4c 49 1. Connect your mbed device to the computer over USB.
pratiksk 0:70cb5a6a3a4c 50 1. Copy the binary file to the mbed device.
pratiksk 0:70cb5a6a3a4c 51 1. Press the reset button to start the program.
pratiksk 0:70cb5a6a3a4c 52
pratiksk 0:70cb5a6a3a4c 53 The LED on your platform turns on and off.
pratiksk 0:70cb5a6a3a4c 54
pratiksk 0:70cb5a6a3a4c 55 ## Export the project to Keil MDK, and debug your application
pratiksk 0:70cb5a6a3a4c 56
pratiksk 0:70cb5a6a3a4c 57 From the command-line, run the following command:
pratiksk 0:70cb5a6a3a4c 58
pratiksk 0:70cb5a6a3a4c 59 ```
pratiksk 0:70cb5a6a3a4c 60 mbed export -m K64F -i uvision
pratiksk 0:70cb5a6a3a4c 61 ```
pratiksk 0:70cb5a6a3a4c 62
pratiksk 0:70cb5a6a3a4c 63 To debug the application:
pratiksk 0:70cb5a6a3a4c 64
pratiksk 0:70cb5a6a3a4c 65 1. Start uVision.
pratiksk 0:70cb5a6a3a4c 66 1. Import the uVision project generated earlier.
pratiksk 0:70cb5a6a3a4c 67 1. Compile your application, and generate an `.axf` file.
pratiksk 0:70cb5a6a3a4c 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).
pratiksk 0:70cb5a6a3a4c 69 1. Set breakpoints, and start a debug session.

pratiksk 0:70cb5a6a3a4c 72
pratiksk 0:70cb5a6a3a4c 73 ## Troubleshooting
pratiksk 0:70cb5a6a3a4c 74
pratiksk 0:70cb5a6a3a4c 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
pratiksk 0:70cb5a6a3a4c 76
pratiksk 0:70cb5a6a3a4c 77 ```
pratiksk 0:70cb5a6a3a4c 78 mbed --version
pratiksk 0:70cb5a6a3a4c 79 ```
pratiksk 0:70cb5a6a3a4c 80
pratiksk 0:70cb5a6a3a4c 81 If not, you can update it:
pratiksk 0:70cb5a6a3a4c 82
pratiksk 0:70cb5a6a3a4c 83 ```
pratiksk 0:70cb5a6a3a4c 84 pip install mbed-cli --upgrade
pratiksk 0:70cb5a6a3a4c 85 ```
pratiksk 0:70cb5a6a3a4c 86
pratiksk 0:70cb5a6a3a4c 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.
