uLipe 0:da8a31f3e0f7 1 # Getting started with Blinky on mbed OS
uLipe 0:da8a31f3e0f7 2
uLipe 0:da8a31f3e0f7 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
uLipe 0:da8a31f3e0f7 4
uLipe 0:da8a31f3e0f7 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
uLipe 0:da8a31f3e0f7 6
uLipe 0:da8a31f3e0f7 7 ## Get the example application!
uLipe 0:da8a31f3e0f7 8
uLipe 0:da8a31f3e0f7 9 From the command line, import the example:
uLipe 0:da8a31f3e0f7 10
uLipe 0:da8a31f3e0f7 11 ```
uLipe 0:da8a31f3e0f7 12 mbed import mbed-os-example-blinky
uLipe 0:da8a31f3e0f7 13 cd mbed-os-example-blinky
uLipe 0:da8a31f3e0f7 14 ```
uLipe 0:da8a31f3e0f7 15
uLipe 0:da8a31f3e0f7 16 ### Now compile
uLipe 0:da8a31f3e0f7 17
uLipe 0:da8a31f3e0f7 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:da8a31f3e0f7 19
uLipe 0:da8a31f3e0f7 20 ```
uLipe 0:da8a31f3e0f7 21 mbed compile -m K64F -t ARM
uLipe 0:da8a31f3e0f7 22 ```
uLipe 0:da8a31f3e0f7 23
uLipe 0:da8a31f3e0f7 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
uLipe 0:da8a31f3e0f7 25
uLipe 0:da8a31f3e0f7 26 ```

uLipe 0:da8a31f3e0f7 47 ### Program your board
uLipe 0:da8a31f3e0f7 48
uLipe 0:da8a31f3e0f7 49 1. Connect your mbed device to the computer over USB.
uLipe 0:da8a31f3e0f7 50 1. Copy the binary file to the mbed device .
uLipe 0:da8a31f3e0f7 51 1. Press the reset button to start the program.
uLipe 0:da8a31f3e0f7 52
uLipe 0:da8a31f3e0f7 53 You should see the LED of your platform turning on and off.
uLipe 0:da8a31f3e0f7 54
uLipe 0:da8a31f3e0f7 55 Congratulations if you managed to complete this test!
uLipe 0:da8a31f3e0f7 56
uLipe 0:da8a31f3e0f7 57 ## Export the project to Keil MDK and debug your application
uLipe 0:da8a31f3e0f7 58
uLipe 0:da8a31f3e0f7 59 From the command line, run the following command:
uLipe 0:da8a31f3e0f7 60
uLipe 0:da8a31f3e0f7 61 ```
uLipe 0:da8a31f3e0f7 62 mbed export -m K64F -i uvision
uLipe 0:da8a31f3e0f7 63 ```
uLipe 0:da8a31f3e0f7 64
uLipe 0:da8a31f3e0f7 65 You should see the following output:
uLipe 0:da8a31f3e0f7 66
uLipe 0:da8a31f3e0f7 67 ```
uLipe 0:da8a31f3e0f7 68 Successful exports:
uLipe 0:da8a31f3e0f7 69 * K64F::uvision .\projectfiles\uvision_K64F\Unnamed_Project
uLipe 0:da8a31f3e0f7 70 ```
uLipe 0:da8a31f3e0f7 71
uLipe 0:da8a31f3e0f7 72 To debug the application:
uLipe 0:da8a31f3e0f7 73
uLipe 0:da8a31f3e0f7 74 1. Start uVision.
uLipe 0:da8a31f3e0f7 75 1. Import the uVision project generated earlier.
uLipe 0:da8a31f3e0f7 76 1. Compile your application and generate an `.axf` file.
uLipe 0:da8a31f3e0f7 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:da8a31f3e0f7 78 1. Set breakpoints and start a debug session.

uLipe 0:da8a31f3e0f7 82 ## Troubleshooting
uLipe 0:da8a31f3e0f7 83
uLipe 0:da8a31f3e0f7 84 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
uLipe 0:da8a31f3e0f7 85
uLipe 0:da8a31f3e0f7 86 ```
uLipe 0:da8a31f3e0f7 87 mbed --version
uLipe 0:da8a31f3e0f7 88 ```
uLipe 0:da8a31f3e0f7 89
uLipe 0:da8a31f3e0f7 90 If not, you can update it easily:
uLipe 0:da8a31f3e0f7 91
uLipe 0:da8a31f3e0f7 92 ```
uLipe 0:da8a31f3e0f7 93 pip install mbed-cli --upgrade
uLipe 0:da8a31f3e0f7 94 ```
uLipe 0:da8a31f3e0f7 95
uLipe 0:da8a31f3e0f7 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.
