wujansin 0:58db089d4478 1 # Getting started with Blinky on mbed OS
wujansin 0:58db089d4478 2
wujansin 0:58db089d4478 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
wujansin 0:58db089d4478 4
wujansin 0:58db089d4478 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
wujansin 0:58db089d4478 6
wujansin 0:58db089d4478 7 ## Import the example application
wujansin 0:58db089d4478 8
wujansin 0:58db089d4478 9 From the command-line, import the example:
wujansin 0:58db089d4478 10
wujansin 0:58db089d4478 11 ```
wujansin 0:58db089d4478 12 mbed import mbed-os-example-blinky
wujansin 0:58db089d4478 13 cd mbed-os-example-blinky
wujansin 0:58db089d4478 14 ```
wujansin 0:58db089d4478 15
wujansin 0:58db089d4478 16 ### Now compile
wujansin 0:58db089d4478 17
wujansin 0:58db089d4478 18 Invoke `mbed compile`, and specify the name of your platform and your favorite toolchain (`GCC_ARM`, `ARM`, `IAR`). For example, for the ARM Compiler 5:
wujansin 0:58db089d4478 19
wujansin 0:58db089d4478 20 ```
wujansin 0:58db089d4478 21 mbed compile -m K64F -t ARM
wujansin 0:58db089d4478 22 ```
wujansin 0:58db089d4478 23
wujansin 0:58db089d4478 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
wujansin 0:58db089d4478 25
wujansin 0:58db089d4478 26 ```

wujansin 0:58db089d4478 47 ### Program your board
wujansin 0:58db089d4478 48
wujansin 0:58db089d4478 49 1. Connect your mbed device to the computer over USB.
wujansin 0:58db089d4478 50 1. Copy the binary file to the mbed device.
wujansin 0:58db089d4478 51 1. Press the reset button to start the program.
wujansin 0:58db089d4478 52
wujansin 0:58db089d4478 53 The LED on your platform turns on and off.
wujansin 0:58db089d4478 54
wujansin 0:58db089d4478 55 ## Export the project to Keil MDK, and debug your application
wujansin 0:58db089d4478 56
wujansin 0:58db089d4478 57 From the command-line, run the following command:
wujansin 0:58db089d4478 58
wujansin 0:58db089d4478 59 ```
wujansin 0:58db089d4478 60 mbed export -m K64F -i uvision
wujansin 0:58db089d4478 61 ```
wujansin 0:58db089d4478 62
wujansin 0:58db089d4478 63 To debug the application:
wujansin 0:58db089d4478 64
wujansin 0:58db089d4478 65 1. Start uVision.
wujansin 0:58db089d4478 66 1. Import the uVision project generated earlier.
wujansin 0:58db089d4478 67 1. Compile your application, and generate an `.axf` file.
wujansin 0:58db089d4478 68 1. Make sure uVision is configured to debug over CMSIS-DAP (From the Project menu > Options for Target '...' > Debug tab > Use CMSIS-DAP Debugger).
wujansin 0:58db089d4478 69 1. Set breakpoints, and start a debug session.

wujansin 0:58db089d4478 73 ## Troubleshooting
wujansin 0:58db089d4478 74
wujansin 0:58db089d4478 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
wujansin 0:58db089d4478 76
wujansin 0:58db089d4478 77 ```
wujansin 0:58db089d4478 78 mbed --version
wujansin 0:58db089d4478 79 ```
wujansin 0:58db089d4478 80
wujansin 0:58db089d4478 81 If not, you can update it:
wujansin 0:58db089d4478 82
wujansin 0:58db089d4478 83 ```
wujansin 0:58db089d4478 84 pip install mbed-cli --upgrade
wujansin 0:58db089d4478 85 ```
wujansin 0:58db089d4478 86
wujansin 0:58db089d4478 87 2. If using Keil MDK, make sure you have a license installed. [MDK-Lite](http://www.keil.com/arm/mdk.asp) has a 32 KB restriction on code size.
