fbdp1202 0:612ab7b3326c 1 # Getting started with Blinky on mbed OS
fbdp1202 0:612ab7b3326c 2
fbdp1202 0:612ab7b3326c 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
fbdp1202 0:612ab7b3326c 4
fbdp1202 0:612ab7b3326c 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
fbdp1202 0:612ab7b3326c 6
fbdp1202 0:612ab7b3326c 7 ## Import the example application
fbdp1202 0:612ab7b3326c 8
fbdp1202 0:612ab7b3326c 9 From the command-line, import the example:
fbdp1202 0:612ab7b3326c 10
fbdp1202 0:612ab7b3326c 11 ```
fbdp1202 0:612ab7b3326c 12 mbed import mbed-os-example-blinky
fbdp1202 0:612ab7b3326c 13 cd mbed-os-example-blinky
fbdp1202 0:612ab7b3326c 14 ```
fbdp1202 0:612ab7b3326c 15
fbdp1202 0:612ab7b3326c 16 ### Now compile
fbdp1202 0:612ab7b3326c 17
fbdp1202 0:612ab7b3326c 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:
fbdp1202 0:612ab7b3326c 19
fbdp1202 0:612ab7b3326c 20 ```
fbdp1202 0:612ab7b3326c 21 mbed compile -m K64F -t ARM
fbdp1202 0:612ab7b3326c 22 ```
fbdp1202 0:612ab7b3326c 23
fbdp1202 0:612ab7b3326c 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
fbdp1202 0:612ab7b3326c 25
fbdp1202 0:612ab7b3326c 26 ```

fbdp1202 0:612ab7b3326c 47 ### Program your board
fbdp1202 0:612ab7b3326c 48
fbdp1202 0:612ab7b3326c 49 1. Connect your mbed device to the computer over USB.
fbdp1202 0:612ab7b3326c 50 1. Copy the binary file to the mbed device.
fbdp1202 0:612ab7b3326c 51 1. Press the reset button to start the program.
fbdp1202 0:612ab7b3326c 52
fbdp1202 0:612ab7b3326c 53 The LED on your platform turns on and off.
fbdp1202 0:612ab7b3326c 54
fbdp1202 0:612ab7b3326c 55 ## Export the project to Keil MDK, and debug your application
fbdp1202 0:612ab7b3326c 56
fbdp1202 0:612ab7b3326c 57 From the command-line, run the following command:
fbdp1202 0:612ab7b3326c 58
fbdp1202 0:612ab7b3326c 59 ```
fbdp1202 0:612ab7b3326c 60 mbed export -m K64F -i uvision
fbdp1202 0:612ab7b3326c 61 ```
fbdp1202 0:612ab7b3326c 62
fbdp1202 0:612ab7b3326c 63 To debug the application:
fbdp1202 0:612ab7b3326c 64
fbdp1202 0:612ab7b3326c 65 1. Start uVision.
fbdp1202 0:612ab7b3326c 66 1. Import the uVision project generated earlier.
fbdp1202 0:612ab7b3326c 67 1. Compile your application, and generate an `.axf` file.
fbdp1202 0:612ab7b3326c 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).
fbdp1202 0:612ab7b3326c 69 1. Set breakpoints, and start a debug session.

fbdp1202 0:612ab7b3326c 73 ## Troubleshooting
fbdp1202 0:612ab7b3326c 74
fbdp1202 0:612ab7b3326c 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
fbdp1202 0:612ab7b3326c 76
fbdp1202 0:612ab7b3326c 77 ```
fbdp1202 0:612ab7b3326c 78 mbed --version
fbdp1202 0:612ab7b3326c 79 ```
fbdp1202 0:612ab7b3326c 80
fbdp1202 0:612ab7b3326c 81 If not, you can update it:
fbdp1202 0:612ab7b3326c 82
fbdp1202 0:612ab7b3326c 83 ```
fbdp1202 0:612ab7b3326c 84 pip install mbed-cli --upgrade
fbdp1202 0:612ab7b3326c 85 ```
fbdp1202 0:612ab7b3326c 86
fbdp1202 0:612ab7b3326c 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.
