Tanakacool 0:f6f2880bef7f 1 # Getting started with Blinky on mbed OS
Tanakacool 0:f6f2880bef7f 2
Tanakacool 0:f6f2880bef7f 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
Tanakacool 0:f6f2880bef7f 4
Tanakacool 0:f6f2880bef7f 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
Tanakacool 0:f6f2880bef7f 6
Tanakacool 0:f6f2880bef7f 7 ## Import the example application
Tanakacool 0:f6f2880bef7f 8
Tanakacool 0:f6f2880bef7f 9 From the command-line, import the example:
Tanakacool 0:f6f2880bef7f 10
Tanakacool 0:f6f2880bef7f 11 ```
Tanakacool 0:f6f2880bef7f 12 mbed import mbed-os-example-blinky
Tanakacool 0:f6f2880bef7f 13 cd mbed-os-example-blinky
Tanakacool 0:f6f2880bef7f 14 ```
Tanakacool 0:f6f2880bef7f 15
Tanakacool 0:f6f2880bef7f 16 ### Now compile
Tanakacool 0:f6f2880bef7f 17
Tanakacool 0:f6f2880bef7f 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:
Tanakacool 0:f6f2880bef7f 19
Tanakacool 0:f6f2880bef7f 20 ```
Tanakacool 0:f6f2880bef7f 21 mbed compile -m K64F -t ARM
Tanakacool 0:f6f2880bef7f 22 ```
Tanakacool 0:f6f2880bef7f 23
Tanakacool 0:f6f2880bef7f 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
Tanakacool 0:f6f2880bef7f 25
Tanakacool 0:f6f2880bef7f 26 ```

Tanakacool 0:f6f2880bef7f 47 ### Program your board
Tanakacool 0:f6f2880bef7f 48
Tanakacool 0:f6f2880bef7f 49 1. Connect your mbed device to the computer over USB.
Tanakacool 0:f6f2880bef7f 50 1. Copy the binary file to the mbed device.
Tanakacool 0:f6f2880bef7f 51 1. Press the reset button to start the program.
Tanakacool 0:f6f2880bef7f 52
Tanakacool 0:f6f2880bef7f 53 The LED on your platform turns on and off.
Tanakacool 0:f6f2880bef7f 54
Tanakacool 0:f6f2880bef7f 55 ## Export the project to Keil MDK, and debug your application
Tanakacool 0:f6f2880bef7f 56
Tanakacool 0:f6f2880bef7f 57 From the command-line, run the following command:
Tanakacool 0:f6f2880bef7f 58
Tanakacool 0:f6f2880bef7f 59 ```
Tanakacool 0:f6f2880bef7f 60 mbed export -m K64F -i uvision
Tanakacool 0:f6f2880bef7f 61 ```
Tanakacool 0:f6f2880bef7f 62
Tanakacool 0:f6f2880bef7f 63 To debug the application:
Tanakacool 0:f6f2880bef7f 64
Tanakacool 0:f6f2880bef7f 65 1. Start uVision.
Tanakacool 0:f6f2880bef7f 66 1. Import the uVision project generated earlier.
Tanakacool 0:f6f2880bef7f 67 1. Compile your application, and generate an `.axf` file.
Tanakacool 0:f6f2880bef7f 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).
Tanakacool 0:f6f2880bef7f 69 1. Set breakpoints, and start a debug session.

Tanakacool 0:f6f2880bef7f 73 ## Troubleshooting
Tanakacool 0:f6f2880bef7f 74
Tanakacool 0:f6f2880bef7f 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
Tanakacool 0:f6f2880bef7f 76
Tanakacool 0:f6f2880bef7f 77 ```
Tanakacool 0:f6f2880bef7f 78 mbed --version
Tanakacool 0:f6f2880bef7f 79 ```
Tanakacool 0:f6f2880bef7f 80
Tanakacool 0:f6f2880bef7f 81 If not, you can update it:
Tanakacool 0:f6f2880bef7f 82
Tanakacool 0:f6f2880bef7f 83 ```
Tanakacool 0:f6f2880bef7f 84 pip install mbed-cli --upgrade
Tanakacool 0:f6f2880bef7f 85 ```
Tanakacool 0:f6f2880bef7f 86
Tanakacool 0:f6f2880bef7f 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.
