shivanandgowdakr 0:0c5fe3ade1bb 1 # Getting started with Blinky on mbed OS
shivanandgowdakr 0:0c5fe3ade1bb 2
shivanandgowdakr 0:0c5fe3ade1bb 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
shivanandgowdakr 0:0c5fe3ade1bb 4
shivanandgowdakr 0:0c5fe3ade1bb 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
shivanandgowdakr 0:0c5fe3ade1bb 6
shivanandgowdakr 0:0c5fe3ade1bb 7 ## Import the example application
shivanandgowdakr 0:0c5fe3ade1bb 8
shivanandgowdakr 0:0c5fe3ade1bb 9 From the command-line, import the example:
shivanandgowdakr 0:0c5fe3ade1bb 10
shivanandgowdakr 0:0c5fe3ade1bb 11 ```
shivanandgowdakr 0:0c5fe3ade1bb 12 mbed import mbed-os-example-blinky
shivanandgowdakr 0:0c5fe3ade1bb 13 cd mbed-os-example-blinky
shivanandgowdakr 0:0c5fe3ade1bb 14 ```
shivanandgowdakr 0:0c5fe3ade1bb 15
shivanandgowdakr 0:0c5fe3ade1bb 16 ### Now compile
shivanandgowdakr 0:0c5fe3ade1bb 17
shivanandgowdakr 0:0c5fe3ade1bb 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:
shivanandgowdakr 0:0c5fe3ade1bb 19
shivanandgowdakr 0:0c5fe3ade1bb 20 ```
shivanandgowdakr 0:0c5fe3ade1bb 21 mbed compile -m K64F -t ARM
shivanandgowdakr 0:0c5fe3ade1bb 22 ```
shivanandgowdakr 0:0c5fe3ade1bb 23
shivanandgowdakr 0:0c5fe3ade1bb 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
shivanandgowdakr 0:0c5fe3ade1bb 25
shivanandgowdakr 0:0c5fe3ade1bb 26 ```

shivanandgowdakr 0:0c5fe3ade1bb 55 ## Export the project to Keil MDK, and debug your application
shivanandgowdakr 0:0c5fe3ade1bb 56
shivanandgowdakr 0:0c5fe3ade1bb 57 From the command-line, run the following command:
shivanandgowdakr 0:0c5fe3ade1bb 58
shivanandgowdakr 0:0c5fe3ade1bb 59 ```
shivanandgowdakr 0:0c5fe3ade1bb 60 mbed export -m K64F -i uvision
shivanandgowdakr 0:0c5fe3ade1bb 61 ```
shivanandgowdakr 0:0c5fe3ade1bb 62
shivanandgowdakr 0:0c5fe3ade1bb 63 To debug the application:
shivanandgowdakr 0:0c5fe3ade1bb 64
shivanandgowdakr 0:0c5fe3ade1bb 65 1. Start uVision.
shivanandgowdakr 0:0c5fe3ade1bb 66 1. Import the uVision project generated earlier.
shivanandgowdakr 0:0c5fe3ade1bb 67 1. Compile your application, and generate an `.axf` file.
shivanandgowdakr 0:0c5fe3ade1bb 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).
shivanandgowdakr 0:0c5fe3ade1bb 69 1. Set breakpoints, and start a debug session.

shivanandgowdakr 0:0c5fe3ade1bb 73 ## Troubleshooting
shivanandgowdakr 0:0c5fe3ade1bb 74
shivanandgowdakr 0:0c5fe3ade1bb 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
shivanandgowdakr 0:0c5fe3ade1bb 76
shivanandgowdakr 0:0c5fe3ade1bb 77 ```
shivanandgowdakr 0:0c5fe3ade1bb 78 mbed --version
shivanandgowdakr 0:0c5fe3ade1bb 79 ```
shivanandgowdakr 0:0c5fe3ade1bb 80
shivanandgowdakr 0:0c5fe3ade1bb 81 If not, you can update it:
shivanandgowdakr 0:0c5fe3ade1bb 82
shivanandgowdakr 0:0c5fe3ade1bb 83 ```
shivanandgowdakr 0:0c5fe3ade1bb 84 pip install mbed-cli --upgrade
shivanandgowdakr 0:0c5fe3ade1bb 85 ```
shivanandgowdakr 0:0c5fe3ade1bb 86
shivanandgowdakr 0:0c5fe3ade1bb 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.
