uLipe 0:ead5ee0a33fa 1 # Getting started with Blinky on mbed OS
uLipe 0:ead5ee0a33fa 2
uLipe 0:ead5ee0a33fa 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
uLipe 0:ead5ee0a33fa 4
uLipe 0:ead5ee0a33fa 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
uLipe 0:ead5ee0a33fa 6
uLipe 0:ead5ee0a33fa 7 ## Get the example application!
uLipe 0:ead5ee0a33fa 8
uLipe 0:ead5ee0a33fa 9 From the command line, import the example:
uLipe 0:ead5ee0a33fa 10
uLipe 0:ead5ee0a33fa 11 ```
uLipe 0:ead5ee0a33fa 12 mbed import mbed-os-example-blinky
uLipe 0:ead5ee0a33fa 13 cd mbed-os-example-blinky
uLipe 0:ead5ee0a33fa 14 ```
uLipe 0:ead5ee0a33fa 15
uLipe 0:ead5ee0a33fa 16 ### Now compile
uLipe 0:ead5ee0a33fa 17
uLipe 0:ead5ee0a33fa 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:ead5ee0a33fa 19
uLipe 0:ead5ee0a33fa 20 ```
uLipe 0:ead5ee0a33fa 21 mbed compile -m K64F -t ARM
uLipe 0:ead5ee0a33fa 22 ```
uLipe 0:ead5ee0a33fa 23
uLipe 0:ead5ee0a33fa 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
uLipe 0:ead5ee0a33fa 25
uLipe 0:ead5ee0a33fa 26 ```

uLipe 0:ead5ee0a33fa 47 ### Program your board
uLipe 0:ead5ee0a33fa 48
uLipe 0:ead5ee0a33fa 49 1. Connect your mbed device to the computer over USB.
uLipe 0:ead5ee0a33fa 50 1. Copy the binary file to the mbed device .
uLipe 0:ead5ee0a33fa 51 1. Press the reset button to start the program.
uLipe 0:ead5ee0a33fa 52
uLipe 0:ead5ee0a33fa 53 You should see the LED of your platform turning on and off.
uLipe 0:ead5ee0a33fa 54
uLipe 0:ead5ee0a33fa 55 Congratulations if you managed to complete this test!

uLipe 0:ead5ee0a33fa 57 ## Export the project to Keil MDK and debug your application
uLipe 0:ead5ee0a33fa 58
uLipe 0:ead5ee0a33fa 59 From the command line, run the following command:
uLipe 0:ead5ee0a33fa 60
uLipe 0:ead5ee0a33fa 61 ```
uLipe 0:ead5ee0a33fa 62 mbed export -m K64F -i uvision
uLipe 0:ead5ee0a33fa 63 ```
uLipe 0:ead5ee0a33fa 64
uLipe 0:ead5ee0a33fa 65 To debug the application:
uLipe 0:ead5ee0a33fa 66
uLipe 0:ead5ee0a33fa 67 1. Start uVision.
uLipe 0:ead5ee0a33fa 68 1. Import the uVision project generated earlier.
uLipe 0:ead5ee0a33fa 69 1. Compile your application and generate an `.axf` file.
uLipe 0:ead5ee0a33fa 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:ead5ee0a33fa 71 1. Set breakpoints and start a debug session.

uLipe 0:ead5ee0a33fa 75 ## Troubleshooting
uLipe 0:ead5ee0a33fa 76
uLipe 0:ead5ee0a33fa 77 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
uLipe 0:ead5ee0a33fa 78
uLipe 0:ead5ee0a33fa 79 ```
uLipe 0:ead5ee0a33fa 80 mbed --version
uLipe 0:ead5ee0a33fa 81 ```
uLipe 0:ead5ee0a33fa 82
uLipe 0:ead5ee0a33fa 83 If not, you can update it easily:
uLipe 0:ead5ee0a33fa 84
uLipe 0:ead5ee0a33fa 85 ```
uLipe 0:ead5ee0a33fa 86 pip install mbed-cli --upgrade
uLipe 0:ead5ee0a33fa 87 ```
uLipe 0:ead5ee0a33fa 88
uLipe 0:ead5ee0a33fa 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.
