sarahmarshy 0:c9ada13905aa 1 # Getting started with Blinky on mbed OS
sarahmarshy 0:c9ada13905aa 2
sarahmarshy 0:c9ada13905aa 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
sarahmarshy 0:c9ada13905aa 4
sarahmarshy 0:c9ada13905aa 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
sarahmarshy 0:c9ada13905aa 6
sarahmarshy 0:c9ada13905aa 7 ## Import the example application
sarahmarshy 0:c9ada13905aa 8
sarahmarshy 0:c9ada13905aa 9 From the command-line, import the example:
sarahmarshy 0:c9ada13905aa 10
sarahmarshy 0:c9ada13905aa 11 ```
sarahmarshy 0:c9ada13905aa 12 mbed import mbed-os-example-blinky
sarahmarshy 0:c9ada13905aa 13 cd mbed-os-example-blinky
sarahmarshy 0:c9ada13905aa 14 ```
sarahmarshy 0:c9ada13905aa 15
sarahmarshy 0:c9ada13905aa 16 ### Now compile
sarahmarshy 0:c9ada13905aa 17
sarahmarshy 0:c9ada13905aa 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:
sarahmarshy 0:c9ada13905aa 19
sarahmarshy 0:c9ada13905aa 20 ```
sarahmarshy 0:c9ada13905aa 21 mbed compile -m K64F -t ARM
sarahmarshy 0:c9ada13905aa 22 ```
sarahmarshy 0:c9ada13905aa 23
sarahmarshy 0:c9ada13905aa 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
sarahmarshy 0:c9ada13905aa 25

sarahmarshy 0:c9ada13905aa 47 ### Program your board
sarahmarshy 0:c9ada13905aa 48
sarahmarshy 0:c9ada13905aa 49 1. Connect your mbed device to the computer over USB.
sarahmarshy 0:c9ada13905aa 50 1. Copy the binary file to the mbed device.
sarahmarshy 0:c9ada13905aa 51 1. Press the reset button to start the program.
sarahmarshy 0:c9ada13905aa 52
sarahmarshy 0:c9ada13905aa 53 The LED on your platform turns on and off.

sarahmarshy 0:c9ada13905aa 55 ## Export the project to Keil MDK, and debug your application
sarahmarshy 0:c9ada13905aa 56
sarahmarshy 0:c9ada13905aa 57 From the command-line, run the following command:
sarahmarshy 0:c9ada13905aa 58
sarahmarshy 0:c9ada13905aa 59 ```
sarahmarshy 0:c9ada13905aa 60 mbed export -m K64F -i uvision
sarahmarshy 0:c9ada13905aa 61 ```
sarahmarshy 0:c9ada13905aa 62
sarahmarshy 0:c9ada13905aa 63 To debug the application:
sarahmarshy 0:c9ada13905aa 64
sarahmarshy 0:c9ada13905aa 65 1. Start uVision.
sarahmarshy 0:c9ada13905aa 66 1. Import the uVision project generated earlier.
sarahmarshy 0:c9ada13905aa 67 1. Compile your application, and generate an `.axf` file.
sarahmarshy 0:c9ada13905aa 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).
sarahmarshy 0:c9ada13905aa 69 1. Set breakpoints, and start a debug session.

sarahmarshy 0:c9ada13905aa 73 ## Troubleshooting
sarahmarshy 0:c9ada13905aa 74
sarahmarshy 0:c9ada13905aa 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
sarahmarshy 0:c9ada13905aa 76
sarahmarshy 0:c9ada13905aa 77 ```
sarahmarshy 0:c9ada13905aa 78 mbed --version
sarahmarshy 0:c9ada13905aa 79 ```
sarahmarshy 0:c9ada13905aa 80
sarahmarshy 0:c9ada13905aa 81 If not, you can update it:
sarahmarshy 0:c9ada13905aa 82
sarahmarshy 0:c9ada13905aa 83 ```
sarahmarshy 0:c9ada13905aa 84 pip install mbed-cli --upgrade
sarahmarshy 0:c9ada13905aa 85 ```
sarahmarshy 0:c9ada13905aa 86
sarahmarshy 0:c9ada13905aa 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.
