uLipe 0:0dc9a3be9863 1 # Getting started with Blinky on mbed OS
uLipe 0:0dc9a3be9863 2
uLipe 0:0dc9a3be9863 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
uLipe 0:0dc9a3be9863 4
uLipe 0:0dc9a3be9863 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
uLipe 0:0dc9a3be9863 6
uLipe 0:0dc9a3be9863 7 ## Get the example application!
uLipe 0:0dc9a3be9863 8
uLipe 0:0dc9a3be9863 9 From the command line, import the example:
uLipe 0:0dc9a3be9863 10
uLipe 0:0dc9a3be9863 11 ```
uLipe 0:0dc9a3be9863 12 mbed import mbed-os-example-blinky
uLipe 0:0dc9a3be9863 13 cd mbed-os-example-blinky
uLipe 0:0dc9a3be9863 14 ```
uLipe 0:0dc9a3be9863 15
uLipe 0:0dc9a3be9863 16 ### Now compile
uLipe 0:0dc9a3be9863 17
uLipe 0:0dc9a3be9863 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 0:0dc9a3be9863 19
uLipe 0:0dc9a3be9863 20 ```
uLipe 0:0dc9a3be9863 21 mbed compile -m K64F -t ARM
uLipe 0:0dc9a3be9863 22 ```
uLipe 0:0dc9a3be9863 23
uLipe 0:0dc9a3be9863 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
uLipe 0:0dc9a3be9863 25
uLipe 0:0dc9a3be9863 26 ```

uLipe 0:0dc9a3be9863 47 ### Program your board
uLipe 0:0dc9a3be9863 48
uLipe 0:0dc9a3be9863 49 1. Connect your mbed device to the computer over USB.
uLipe 0:0dc9a3be9863 50 1. Copy the binary file to the mbed device .
uLipe 0:0dc9a3be9863 51 1. Press the reset button to start the program.
uLipe 0:0dc9a3be9863 52
uLipe 0:0dc9a3be9863 53 You should see the LED of your platform turning on and off.
uLipe 0:0dc9a3be9863 54
uLipe 0:0dc9a3be9863 55 Congratulations if you managed to complete this test!

uLipe 0:0dc9a3be9863 57 ## Export the project to Keil MDK and debug your application
uLipe 0:0dc9a3be9863 58
uLipe 0:0dc9a3be9863 59 From the command line, run the following command:
uLipe 0:0dc9a3be9863 60
uLipe 0:0dc9a3be9863 61 ```
uLipe 0:0dc9a3be9863 62 mbed export -m K64F -i uvision
uLipe 0:0dc9a3be9863 63 ```
uLipe 0:0dc9a3be9863 64
uLipe 0:0dc9a3be9863 65 You should see the following output:
uLipe 0:0dc9a3be9863 66
uLipe 0:0dc9a3be9863 67 ```
uLipe 0:0dc9a3be9863 68 Successful exports:
uLipe 0:0dc9a3be9863 69 * K64F::uvision .\projectfiles\uvision_K64F\Unnamed_Project
uLipe 0:0dc9a3be9863 70 ```
uLipe 0:0dc9a3be9863 71
uLipe 0:0dc9a3be9863 72 To debug the application:
uLipe 0:0dc9a3be9863 73
uLipe 0:0dc9a3be9863 74 1. Start uVision.
uLipe 0:0dc9a3be9863 75 1. Import the uVision project generated earlier.
uLipe 0:0dc9a3be9863 76 1. Compile your application and generate an `.axf` file.
uLipe 0:0dc9a3be9863 77 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 0:0dc9a3be9863 78 1. Set breakpoints and start a debug session.

uLipe 0:0dc9a3be9863 82 ## Troubleshooting
uLipe 0:0dc9a3be9863 83
uLipe 0:0dc9a3be9863 84 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
uLipe 0:0dc9a3be9863 85
uLipe 0:0dc9a3be9863 86 ```
uLipe 0:0dc9a3be9863 87 mbed --version
uLipe 0:0dc9a3be9863 88 ```
uLipe 0:0dc9a3be9863 89
uLipe 0:0dc9a3be9863 90 If not, you can update it easily:
uLipe 0:0dc9a3be9863 91
uLipe 0:0dc9a3be9863 92 ```
uLipe 0:0dc9a3be9863 93 pip install mbed-cli --upgrade
uLipe 0:0dc9a3be9863 94 ```
uLipe 0:0dc9a3be9863 95
uLipe 0:0dc9a3be9863 96 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.
