sarahmarshy 0:501aab314b48 1 # Getting started with Blinky on mbed OS
sarahmarshy 0:501aab314b48 2
sarahmarshy 0:501aab314b48 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
sarahmarshy 0:501aab314b48 4
sarahmarshy 0:501aab314b48 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
sarahmarshy 0:501aab314b48 6
sarahmarshy 0:501aab314b48 7 ## Get the example application!
sarahmarshy 0:501aab314b48 8
sarahmarshy 0:501aab314b48 9 From the command line, import the example:
sarahmarshy 0:501aab314b48 10
sarahmarshy 0:501aab314b48 11 ```
sarahmarshy 0:501aab314b48 12 mbed import mbed-os-example-blinky
sarahmarshy 0:501aab314b48 13 cd mbed-os-example-blinky
sarahmarshy 0:501aab314b48 14 ```
sarahmarshy 0:501aab314b48 15
sarahmarshy 0:501aab314b48 16 ### Now compile
sarahmarshy 0:501aab314b48 17
sarahmarshy 0:501aab314b48 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:
sarahmarshy 0:501aab314b48 19
sarahmarshy 0:501aab314b48 20 ```
sarahmarshy 0:501aab314b48 21 mbed compile -m K64F -t ARM
sarahmarshy 0:501aab314b48 22 ```
sarahmarshy 0:501aab314b48 23
sarahmarshy 0:501aab314b48 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
sarahmarshy 0:501aab314b48 25
sarahmarshy 0:501aab314b48 26 ```

sarahmarshy 0:501aab314b48 47 ### Program your board
sarahmarshy 0:501aab314b48 48
sarahmarshy 0:501aab314b48 49 1. Connect your mbed device to the computer over USB.
sarahmarshy 0:501aab314b48 50 1. Copy the binary file to the mbed device .
sarahmarshy 0:501aab314b48 51 1. Press the reset button to start the program.
sarahmarshy 0:501aab314b48 52
sarahmarshy 0:501aab314b48 53 You should see the LED of your platform turning on and off.

sarahmarshy 0:501aab314b48 57 ## Export the project to Keil MDK and debug your application
sarahmarshy 0:501aab314b48 58
sarahmarshy 0:501aab314b48 59 From the command line, run the following command:
sarahmarshy 0:501aab314b48 60
sarahmarshy 0:501aab314b48 61 ```
sarahmarshy 0:501aab314b48 62 mbed export -m K64F -i uvision
sarahmarshy 0:501aab314b48 63 ```
sarahmarshy 0:501aab314b48 64
sarahmarshy 0:501aab314b48 65 You should see the following output:

sarahmarshy 0:501aab314b48 67 ```
sarahmarshy 0:501aab314b48 68 Successful exports:
sarahmarshy 0:501aab314b48 69 * K64F::uvision .\projectfiles\uvision_K64F\Unnamed_Project
sarahmarshy 0:501aab314b48 70 ```
sarahmarshy 0:501aab314b48 71
sarahmarshy 0:501aab314b48 72 To debug the application:
sarahmarshy 0:501aab314b48 73
sarahmarshy 0:501aab314b48 74 1. Start uVision.
sarahmarshy 0:501aab314b48 75 1. Import the uVision project generated earlier.
sarahmarshy 0:501aab314b48 76 1. Compile your application and generate an `.axf` file.
sarahmarshy 0:501aab314b48 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).
sarahmarshy 0:501aab314b48 78 1. Set breakpoints and start a debug session.

sarahmarshy 0:501aab314b48 82 ## Troubleshooting
sarahmarshy 0:501aab314b48 83
sarahmarshy 0:501aab314b48 84 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
sarahmarshy 0:501aab314b48 85
sarahmarshy 0:501aab314b48 86 ```
sarahmarshy 0:501aab314b48 87 mbed --version
sarahmarshy 0:501aab314b48 88 ```
sarahmarshy 0:501aab314b48 89
sarahmarshy 0:501aab314b48 90 If not, you can update it easily:
sarahmarshy 0:501aab314b48 91
sarahmarshy 0:501aab314b48 92 ```
sarahmarshy 0:501aab314b48 93 pip install mbed-cli --upgrade
sarahmarshy 0:501aab314b48 94 ```
sarahmarshy 0:501aab314b48 95
sarahmarshy 0:501aab314b48 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.
