noutram 0:397b84c74d17 1 # Getting started with Blinky on mbed OS
noutram 0:397b84c74d17 2
noutram 0:397b84c74d17 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
noutram 0:397b84c74d17 4
noutram 0:397b84c74d17 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
noutram 0:397b84c74d17 6
noutram 0:397b84c74d17 7 ## Import the example application
noutram 0:397b84c74d17 8
noutram 0:397b84c74d17 9 From the command-line, import the example:
noutram 0:397b84c74d17 10
noutram 0:397b84c74d17 11 ```
noutram 0:397b84c74d17 12 mbed import mbed-os-example-blinky
noutram 0:397b84c74d17 13 cd mbed-os-example-blinky
noutram 0:397b84c74d17 14 ```
noutram 0:397b84c74d17 15
noutram 0:397b84c74d17 16 ### Now compile
noutram 0:397b84c74d17 17
noutram 0:397b84c74d17 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:
noutram 0:397b84c74d17 19
noutram 0:397b84c74d17 20 ```
noutram 0:397b84c74d17 21 mbed compile -m K64F -t ARM
noutram 0:397b84c74d17 22 ```
noutram 0:397b84c74d17 23
noutram 0:397b84c74d17 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
noutram 0:397b84c74d17 25
noutram 0:397b84c74d17 26 ```

noutram 0:397b84c74d17 47 ### Program your board
noutram 0:397b84c74d17 48
noutram 0:397b84c74d17 49 1. Connect your mbed device to the computer over USB.
noutram 0:397b84c74d17 50 1. Copy the binary file to the mbed device.
noutram 0:397b84c74d17 51 1. Press the reset button to start the program.
noutram 0:397b84c74d17 52
noutram 0:397b84c74d17 53 The LED on your platform turns on and off.
noutram 0:397b84c74d17 54
noutram 0:397b84c74d17 55 ## Export the project to Keil MDK, and debug your application
noutram 0:397b84c74d17 56
noutram 0:397b84c74d17 57 From the command-line, run the following command:
noutram 0:397b84c74d17 58
noutram 0:397b84c74d17 59 ```
noutram 0:397b84c74d17 60 mbed export -m K64F -i uvision
noutram 0:397b84c74d17 61 ```
noutram 0:397b84c74d17 62
noutram 0:397b84c74d17 63 To debug the application:
noutram 0:397b84c74d17 64
noutram 0:397b84c74d17 65 1. Start uVision.
noutram 0:397b84c74d17 66 1. Import the uVision project generated earlier.
noutram 0:397b84c74d17 67 1. Compile your application, and generate an `.axf` file.
noutram 0:397b84c74d17 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).
noutram 0:397b84c74d17 69 1. Set breakpoints, and start a debug session.

noutram 0:397b84c74d17 73 ## Troubleshooting
noutram 0:397b84c74d17 74
noutram 0:397b84c74d17 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
noutram 0:397b84c74d17 76
noutram 0:397b84c74d17 77 ```
noutram 0:397b84c74d17 78 mbed --version
noutram 0:397b84c74d17 79 ```
noutram 0:397b84c74d17 80
noutram 0:397b84c74d17 81 If not, you can update it:
noutram 0:397b84c74d17 82
noutram 0:397b84c74d17 83 ```
noutram 0:397b84c74d17 84 pip install mbed-cli --upgrade
noutram 0:397b84c74d17 85 ```
noutram 0:397b84c74d17 86
noutram 0:397b84c74d17 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.
