uLipe 0:d767141a0a9c 1 # Getting started with Blinky on mbed OS
uLipe 0:d767141a0a9c 2
uLipe 0:d767141a0a9c 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
uLipe 0:d767141a0a9c 4
uLipe 0:d767141a0a9c 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
uLipe 0:d767141a0a9c 6
uLipe 0:d767141a0a9c 7 ## Get the example application!
uLipe 0:d767141a0a9c 8
uLipe 0:d767141a0a9c 9 From the command line, import the example:
uLipe 0:d767141a0a9c 10
uLipe 0:d767141a0a9c 11 ```
uLipe 0:d767141a0a9c 12 mbed import mbed-os-example-blinky
uLipe 0:d767141a0a9c 13 cd mbed-os-example-blinky
uLipe 0:d767141a0a9c 14 ```
uLipe 0:d767141a0a9c 15
uLipe 0:d767141a0a9c 16 ### Now compile
uLipe 0:d767141a0a9c 17
uLipe 0:d767141a0a9c 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:d767141a0a9c 19
uLipe 0:d767141a0a9c 20 ```
uLipe 0:d767141a0a9c 21 mbed compile -m K64F -t ARM
uLipe 0:d767141a0a9c 22 ```
uLipe 0:d767141a0a9c 23
uLipe 0:d767141a0a9c 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
uLipe 0:d767141a0a9c 25
uLipe 0:d767141a0a9c 26 ```

uLipe 0:d767141a0a9c 47 ### Program your board
uLipe 0:d767141a0a9c 48
uLipe 0:d767141a0a9c 49 1. Connect your mbed device to the computer over USB.
uLipe 0:d767141a0a9c 50 1. Copy the binary file to the mbed device .
uLipe 0:d767141a0a9c 51 1. Press the reset button to start the program.
uLipe 0:d767141a0a9c 52
uLipe 0:d767141a0a9c 53 You should see the LED of your platform turning on and off.
uLipe 0:d767141a0a9c 54
uLipe 0:d767141a0a9c 55 Congratulations if you managed to complete this test!
uLipe 0:d767141a0a9c 56
uLipe 0:d767141a0a9c 57 ## Export the project to Keil MDK and debug your application
uLipe 0:d767141a0a9c 58
uLipe 0:d767141a0a9c 59 From the command line, run the following command:
uLipe 0:d767141a0a9c 60
uLipe 0:d767141a0a9c 61 ```
uLipe 0:d767141a0a9c 62 mbed export -m K64F -i uvision
uLipe 0:d767141a0a9c 63 ```
uLipe 0:d767141a0a9c 64
uLipe 0:d767141a0a9c 65 You should see the following output:
uLipe 0:d767141a0a9c 66

uLipe 0:d767141a0a9c 68 Successful exports:
uLipe 0:d767141a0a9c 69 * K64F::uvision .\projectfiles\uvision_K64F\Unnamed_Project
uLipe 0:d767141a0a9c 70 ```
uLipe 0:d767141a0a9c 71
uLipe 0:d767141a0a9c 72 To debug the application:
uLipe 0:d767141a0a9c 73
uLipe 0:d767141a0a9c 74 1. Start uVision.
uLipe 0:d767141a0a9c 75 1. Import the uVision project generated earlier.
uLipe 0:d767141a0a9c 76 1. Compile your application and generate an `.axf` file.
uLipe 0:d767141a0a9c 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:d767141a0a9c 78 1. Set breakpoints and start a debug session.

uLipe 0:d767141a0a9c 82 ## Troubleshooting
uLipe 0:d767141a0a9c 83
uLipe 0:d767141a0a9c 84 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
uLipe 0:d767141a0a9c 85
uLipe 0:d767141a0a9c 86 ```
uLipe 0:d767141a0a9c 87 mbed --version
uLipe 0:d767141a0a9c 88 ```
uLipe 0:d767141a0a9c 89
uLipe 0:d767141a0a9c 90 If not, you can update it easily:
uLipe 0:d767141a0a9c 91
uLipe 0:d767141a0a9c 92 ```
uLipe 0:d767141a0a9c 93 pip install mbed-cli --upgrade
uLipe 0:d767141a0a9c 94 ```
uLipe 0:d767141a0a9c 95
uLipe 0:d767141a0a9c 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.
