uLipe 0:a59680ccdb41 1 # Getting started with Blinky on mbed OS
uLipe 0:a59680ccdb41 2
uLipe 0:a59680ccdb41 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
uLipe 0:a59680ccdb41 4
uLipe 0:a59680ccdb41 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
uLipe 0:a59680ccdb41 6
uLipe 0:a59680ccdb41 7 ## Get the example application!
uLipe 0:a59680ccdb41 8
uLipe 0:a59680ccdb41 9 From the command line, import the example:
uLipe 0:a59680ccdb41 10
uLipe 0:a59680ccdb41 11 ```
uLipe 0:a59680ccdb41 12 mbed import mbed-os-example-blinky
uLipe 0:a59680ccdb41 13 cd mbed-os-example-blinky
uLipe 0:a59680ccdb41 14 ```
uLipe 0:a59680ccdb41 15
uLipe 0:a59680ccdb41 16 ### Now compile
uLipe 0:a59680ccdb41 17
uLipe 0:a59680ccdb41 18 Invoke `mbed compile` specifying the name of your platform and your favorite toolchain (`GCC_ARM`, `ARM`, `IAR`). For example, for the ARM Compiler 5:
uLipe 0:a59680ccdb41 19
uLipe 0:a59680ccdb41 20 ```
uLipe 0:a59680ccdb41 21 mbed compile -m K64F -t ARM
uLipe 0:a59680ccdb41 22 ```
uLipe 0:a59680ccdb41 23
uLipe 0:a59680ccdb41 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
uLipe 0:a59680ccdb41 25
uLipe 0:a59680ccdb41 26 ```

uLipe 0:a59680ccdb41 47 ### Program your board
uLipe 0:a59680ccdb41 48
uLipe 0:a59680ccdb41 49 1. Connect your mbed device to the computer over USB.
uLipe 0:a59680ccdb41 50 1. Copy the binary file to the mbed device .
uLipe 0:a59680ccdb41 51 1. Press the reset button to start the program.
uLipe 0:a59680ccdb41 52
uLipe 0:a59680ccdb41 53 You should see the LED of your platform turning on and off.
uLipe 0:a59680ccdb41 54
uLipe 0:a59680ccdb41 55 Congratulations if you managed to complete this test!

uLipe 0:a59680ccdb41 57 ## Export the project to Keil MDK and debug your application
uLipe 0:a59680ccdb41 58
uLipe 0:a59680ccdb41 59 From the command line, run the following command:
uLipe 0:a59680ccdb41 60
uLipe 0:a59680ccdb41 61 ```
uLipe 0:a59680ccdb41 62 mbed export -m K64F -i uvision
uLipe 0:a59680ccdb41 63 ```
uLipe 0:a59680ccdb41 64
uLipe 0:a59680ccdb41 65 To debug the application:
uLipe 0:a59680ccdb41 66
uLipe 0:a59680ccdb41 67 1. Start uVision.
uLipe 0:a59680ccdb41 68 1. Import the uVision project generated earlier.
uLipe 0:a59680ccdb41 69 1. Compile your application and generate an `.axf` file.
uLipe 0:a59680ccdb41 70 1. Make sure uVision is configured to debug over CMSIS-DAP (From the Project menu > Options for Target '...' > Debug tab > Use CMSIS-DAP Debugger).
uLipe 0:a59680ccdb41 71 1. Set breakpoints and start a debug session.

uLipe 0:a59680ccdb41 75 ## Troubleshooting
uLipe 0:a59680ccdb41 76
uLipe 0:a59680ccdb41 77 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
uLipe 0:a59680ccdb41 78
uLipe 0:a59680ccdb41 79 ```
uLipe 0:a59680ccdb41 80 mbed --version
uLipe 0:a59680ccdb41 81 ```
uLipe 0:a59680ccdb41 82
uLipe 0:a59680ccdb41 83 If not, you can update it easily:
uLipe 0:a59680ccdb41 84
uLipe 0:a59680ccdb41 85 ```
uLipe 0:a59680ccdb41 86 pip install mbed-cli --upgrade
uLipe 0:a59680ccdb41 87 ```
uLipe 0:a59680ccdb41 88
uLipe 0:a59680ccdb41 89 2. If using Keil MDK, make sure you have a license installed. [MDK-Lite](http://www.keil.com/arm/mdk.asp) has a 32KB restriction on code size.
