JavierGC 0:1c1c9f47b8ad 1 # Getting started with Blinky on mbed OS
JavierGC 0:1c1c9f47b8ad 2
JavierGC 0:1c1c9f47b8ad 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
JavierGC 0:1c1c9f47b8ad 4
JavierGC 0:1c1c9f47b8ad 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
JavierGC 0:1c1c9f47b8ad 6
JavierGC 0:1c1c9f47b8ad 7 ## Import the example application
JavierGC 0:1c1c9f47b8ad 8
JavierGC 0:1c1c9f47b8ad 9 From the command-line, import the example:
JavierGC 0:1c1c9f47b8ad 10
JavierGC 0:1c1c9f47b8ad 11 ```
JavierGC 0:1c1c9f47b8ad 12 mbed import mbed-os-example-blinky
JavierGC 0:1c1c9f47b8ad 13 cd mbed-os-example-blinky
JavierGC 0:1c1c9f47b8ad 14 ```
JavierGC 0:1c1c9f47b8ad 15
JavierGC 0:1c1c9f47b8ad 16 ### Now compile
JavierGC 0:1c1c9f47b8ad 17
JavierGC 0:1c1c9f47b8ad 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:
JavierGC 0:1c1c9f47b8ad 19
JavierGC 0:1c1c9f47b8ad 20 ```
JavierGC 0:1c1c9f47b8ad 21 mbed compile -m K64F -t ARM
JavierGC 0:1c1c9f47b8ad 22 ```
JavierGC 0:1c1c9f47b8ad 23
JavierGC 0:1c1c9f47b8ad 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
JavierGC 0:1c1c9f47b8ad 25

JavierGC 0:1c1c9f47b8ad 47 ### Program your board
JavierGC 0:1c1c9f47b8ad 48
JavierGC 0:1c1c9f47b8ad 49 1. Connect your mbed device to the computer over USB.
JavierGC 0:1c1c9f47b8ad 50 1. Copy the binary file to the mbed device.
JavierGC 0:1c1c9f47b8ad 51 1. Press the reset button to start the program.
JavierGC 0:1c1c9f47b8ad 52
JavierGC 0:1c1c9f47b8ad 53 The LED on your platform turns on and off.
JavierGC 0:1c1c9f47b8ad 54
JavierGC 0:1c1c9f47b8ad 55 ## Export the project to Keil MDK, and debug your application
JavierGC 0:1c1c9f47b8ad 56
JavierGC 0:1c1c9f47b8ad 57 From the command-line, run the following command:
JavierGC 0:1c1c9f47b8ad 58
JavierGC 0:1c1c9f47b8ad 59 ```
JavierGC 0:1c1c9f47b8ad 60 mbed export -m K64F -i uvision
JavierGC 0:1c1c9f47b8ad 61 ```
JavierGC 0:1c1c9f47b8ad 62
JavierGC 0:1c1c9f47b8ad 63 To debug the application:
JavierGC 0:1c1c9f47b8ad 64
JavierGC 0:1c1c9f47b8ad 65 1. Start uVision.
JavierGC 0:1c1c9f47b8ad 66 1. Import the uVision project generated earlier.
JavierGC 0:1c1c9f47b8ad 67 1. Compile your application, and generate an `.axf` file.
JavierGC 0:1c1c9f47b8ad 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).
JavierGC 0:1c1c9f47b8ad 69 1. Set breakpoints, and start a debug session.

JavierGC 0:1c1c9f47b8ad 73 ## Troubleshooting
JavierGC 0:1c1c9f47b8ad 74
JavierGC 0:1c1c9f47b8ad 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
JavierGC 0:1c1c9f47b8ad 76
JavierGC 0:1c1c9f47b8ad 77 ```
JavierGC 0:1c1c9f47b8ad 78 mbed --version
JavierGC 0:1c1c9f47b8ad 79 ```
JavierGC 0:1c1c9f47b8ad 80
JavierGC 0:1c1c9f47b8ad 81 If not, you can update it:
JavierGC 0:1c1c9f47b8ad 82
JavierGC 0:1c1c9f47b8ad 83 ```
JavierGC 0:1c1c9f47b8ad 84 pip install mbed-cli --upgrade
JavierGC 0:1c1c9f47b8ad 85 ```
JavierGC 0:1c1c9f47b8ad 86
JavierGC 0:1c1c9f47b8ad 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.
