leandropg 0:317ba4466741 1 # Getting started with Blinky on mbed OS
leandropg 0:317ba4466741 2
leandropg 0:317ba4466741 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
leandropg 0:317ba4466741 4
leandropg 0:317ba4466741 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
leandropg 0:317ba4466741 6
leandropg 0:317ba4466741 7 ## Import the example application
leandropg 0:317ba4466741 8
leandropg 0:317ba4466741 9 From the command-line, import the example:
leandropg 0:317ba4466741 10
leandropg 0:317ba4466741 11 ```
leandropg 0:317ba4466741 12 mbed import mbed-os-example-blinky
leandropg 0:317ba4466741 13 cd mbed-os-example-blinky
leandropg 0:317ba4466741 14 ```
leandropg 0:317ba4466741 15
leandropg 0:317ba4466741 16 ### Now compile
leandropg 0:317ba4466741 17
leandropg 0:317ba4466741 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:
leandropg 0:317ba4466741 19
leandropg 0:317ba4466741 20 ```
leandropg 0:317ba4466741 21 mbed compile -m K64F -t ARM
leandropg 0:317ba4466741 22 ```
leandropg 0:317ba4466741 23
leandropg 0:317ba4466741 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
leandropg 0:317ba4466741 25
leandropg 0:317ba4466741 26 ```

leandropg 0:317ba4466741 47 ### Program your board
leandropg 0:317ba4466741 48
leandropg 0:317ba4466741 49 1. Connect your mbed device to the computer over USB.
leandropg 0:317ba4466741 50 1. Copy the binary file to the mbed device.
leandropg 0:317ba4466741 51 1. Press the reset button to start the program.
leandropg 0:317ba4466741 52
leandropg 0:317ba4466741 53 The LED on your platform turns on and off.

leandropg 0:317ba4466741 55 ## Export the project to Keil MDK, and debug your application
leandropg 0:317ba4466741 56
leandropg 0:317ba4466741 57 From the command-line, run the following command:
leandropg 0:317ba4466741 58
leandropg 0:317ba4466741 59 ```
leandropg 0:317ba4466741 60 mbed export -m K64F -i uvision
leandropg 0:317ba4466741 61 ```
leandropg 0:317ba4466741 62
leandropg 0:317ba4466741 63 To debug the application:
leandropg 0:317ba4466741 64
leandropg 0:317ba4466741 65 1. Start uVision.
leandropg 0:317ba4466741 66 1. Import the uVision project generated earlier.
leandropg 0:317ba4466741 67 1. Compile your application, and generate an `.axf` file.
leandropg 0:317ba4466741 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).
leandropg 0:317ba4466741 69 1. Set breakpoints, and start a debug session.

leandropg 0:317ba4466741 73 ## Troubleshooting
leandropg 0:317ba4466741 74
leandropg 0:317ba4466741 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
leandropg 0:317ba4466741 76
leandropg 0:317ba4466741 77 ```
leandropg 0:317ba4466741 78 mbed --version
leandropg 0:317ba4466741 79 ```
leandropg 0:317ba4466741 80
leandropg 0:317ba4466741 81 If not, you can update it:
leandropg 0:317ba4466741 82
leandropg 0:317ba4466741 83 ```
leandropg 0:317ba4466741 84 pip install mbed-cli --upgrade
leandropg 0:317ba4466741 85 ```
leandropg 0:317ba4466741 86
leandropg 0:317ba4466741 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.
