agaikwad 0:dbba16496f3e 1 # Getting started with Blinky on mbed OS
agaikwad 0:dbba16496f3e 2
agaikwad 0:dbba16496f3e 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
agaikwad 0:dbba16496f3e 4
agaikwad 0:dbba16496f3e 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
agaikwad 0:dbba16496f3e 6
agaikwad 0:dbba16496f3e 7 ## Import the example application
agaikwad 0:dbba16496f3e 8
agaikwad 0:dbba16496f3e 9 From the command-line, import the example:
agaikwad 0:dbba16496f3e 10
agaikwad 0:dbba16496f3e 11 ```
agaikwad 0:dbba16496f3e 12 mbed import mbed-os-example-blinky
agaikwad 0:dbba16496f3e 13 cd mbed-os-example-blinky
agaikwad 0:dbba16496f3e 14 ```
agaikwad 0:dbba16496f3e 15
agaikwad 0:dbba16496f3e 16 ### Now compile
agaikwad 0:dbba16496f3e 17
agaikwad 0:dbba16496f3e 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:
agaikwad 0:dbba16496f3e 19
agaikwad 0:dbba16496f3e 20 ```
agaikwad 0:dbba16496f3e 21 mbed compile -m K64F -t ARM
agaikwad 0:dbba16496f3e 22 ```
agaikwad 0:dbba16496f3e 23
agaikwad 0:dbba16496f3e 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
agaikwad 0:dbba16496f3e 25
agaikwad 0:dbba16496f3e 26 ```

agaikwad 0:dbba16496f3e 55 ## Export the project to Keil MDK, and debug your application
agaikwad 0:dbba16496f3e 56
agaikwad 0:dbba16496f3e 57 From the command-line, run the following command:
agaikwad 0:dbba16496f3e 58
agaikwad 0:dbba16496f3e 59 ```
agaikwad 0:dbba16496f3e 60 mbed export -m K64F -i uvision
agaikwad 0:dbba16496f3e 61 ```
agaikwad 0:dbba16496f3e 62
agaikwad 0:dbba16496f3e 63 To debug the application:
agaikwad 0:dbba16496f3e 64
agaikwad 0:dbba16496f3e 65 1. Start uVision.
agaikwad 0:dbba16496f3e 66 1. Import the uVision project generated earlier.
agaikwad 0:dbba16496f3e 67 1. Compile your application, and generate an `.axf` file.
agaikwad 0:dbba16496f3e 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).
agaikwad 0:dbba16496f3e 69 1. Set breakpoints, and start a debug session.

agaikwad 0:dbba16496f3e 73 ## Troubleshooting
agaikwad 0:dbba16496f3e 74
agaikwad 0:dbba16496f3e 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
agaikwad 0:dbba16496f3e 76
agaikwad 0:dbba16496f3e 77 ```
agaikwad 0:dbba16496f3e 78 mbed --version
agaikwad 0:dbba16496f3e 79 ```
agaikwad 0:dbba16496f3e 80
agaikwad 0:dbba16496f3e 81 If not, you can update it:
agaikwad 0:dbba16496f3e 82
agaikwad 0:dbba16496f3e 83 ```
agaikwad 0:dbba16496f3e 84 pip install mbed-cli --upgrade
agaikwad 0:dbba16496f3e 85 ```
agaikwad 0:dbba16496f3e 86
agaikwad 0:dbba16496f3e 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.
