argusbrown 0:2030e4f70e25 1 # Getting started with Blinky on mbed OS
argusbrown 0:2030e4f70e25 2
argusbrown 0:2030e4f70e25 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
argusbrown 0:2030e4f70e25 4
argusbrown 0:2030e4f70e25 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
argusbrown 0:2030e4f70e25 6
argusbrown 0:2030e4f70e25 7 ## Get the example application!
argusbrown 0:2030e4f70e25 8
argusbrown 0:2030e4f70e25 9 From the command line, import the example:
argusbrown 0:2030e4f70e25 10
argusbrown 0:2030e4f70e25 11 ```
argusbrown 0:2030e4f70e25 12 mbed import mbed-os-example-blinky
argusbrown 0:2030e4f70e25 13 cd mbed-os-example-blinky
argusbrown 0:2030e4f70e25 14 ```
argusbrown 0:2030e4f70e25 15
argusbrown 0:2030e4f70e25 16 ### Now compile
argusbrown 0:2030e4f70e25 17
argusbrown 0:2030e4f70e25 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:
argusbrown 0:2030e4f70e25 19
argusbrown 0:2030e4f70e25 20 ```
argusbrown 0:2030e4f70e25 21 mbed compile -m K64F -t ARM
argusbrown 0:2030e4f70e25 22 ```
argusbrown 0:2030e4f70e25 23
argusbrown 0:2030e4f70e25 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
argusbrown 0:2030e4f70e25 25
argusbrown 0:2030e4f70e25 26 ```

argusbrown 0:2030e4f70e25 47 ### Program your board
argusbrown 0:2030e4f70e25 48
argusbrown 0:2030e4f70e25 49 1. Connect your mbed device to the computer over USB.
argusbrown 0:2030e4f70e25 50 1. Copy the binary file to the mbed device .
argusbrown 0:2030e4f70e25 51 1. Press the reset button to start the program.
argusbrown 0:2030e4f70e25 52
argusbrown 0:2030e4f70e25 53 You should see the LED of your platform turning on and off.
argusbrown 0:2030e4f70e25 54
argusbrown 0:2030e4f70e25 55 Congratulations if you managed to complete this test!
argusbrown 0:2030e4f70e25 56
argusbrown 0:2030e4f70e25 57 ## Export the project to Keil MDK and debug your application
argusbrown 0:2030e4f70e25 58
argusbrown 0:2030e4f70e25 59 From the command line, run the following command:
argusbrown 0:2030e4f70e25 60
argusbrown 0:2030e4f70e25 61 ```
argusbrown 0:2030e4f70e25 62 mbed export -m K64F -i uvision
argusbrown 0:2030e4f70e25 63 ```
argusbrown 0:2030e4f70e25 64
argusbrown 0:2030e4f70e25 65 You should see the following output:
argusbrown 0:2030e4f70e25 66
argusbrown 0:2030e4f70e25 67 ```
argusbrown 0:2030e4f70e25 68 Successful exports:
argusbrown 0:2030e4f70e25 69 * K64F::uvision .\projectfiles\uvision_K64F\Unnamed_Project
argusbrown 0:2030e4f70e25 70 ```
argusbrown 0:2030e4f70e25 71
argusbrown 0:2030e4f70e25 72 To debug the application:
argusbrown 0:2030e4f70e25 73
argusbrown 0:2030e4f70e25 74 1. Start uVision.
argusbrown 0:2030e4f70e25 75 1. Import the uVision project generated earlier.
argusbrown 0:2030e4f70e25 76 1. Compile your application and generate an `.axf` file.
argusbrown 0:2030e4f70e25 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).
argusbrown 0:2030e4f70e25 78 1. Set breakpoints and start a debug session.

argusbrown 0:2030e4f70e25 82 ## Troubleshooting
argusbrown 0:2030e4f70e25 83
argusbrown 0:2030e4f70e25 84 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
argusbrown 0:2030e4f70e25 85
argusbrown 0:2030e4f70e25 86 ```
argusbrown 0:2030e4f70e25 87 mbed --version
argusbrown 0:2030e4f70e25 88 ```
argusbrown 0:2030e4f70e25 89
argusbrown 0:2030e4f70e25 90 If not, you can update it easily:
argusbrown 0:2030e4f70e25 91
argusbrown 0:2030e4f70e25 92 ```
argusbrown 0:2030e4f70e25 93 pip install mbed-cli --upgrade
argusbrown 0:2030e4f70e25 94 ```
argusbrown 0:2030e4f70e25 95
argusbrown 0:2030e4f70e25 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.
