seyfrid_L 0:ce8ad4f285d3 1 # Getting started with Blinky on mbed OS
seyfrid_L 0:ce8ad4f285d3 2
seyfrid_L 0:ce8ad4f285d3 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
seyfrid_L 0:ce8ad4f285d3 4
seyfrid_L 0:ce8ad4f285d3 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
seyfrid_L 0:ce8ad4f285d3 6
seyfrid_L 0:ce8ad4f285d3 7 ## Import the example application
seyfrid_L 0:ce8ad4f285d3 8
seyfrid_L 0:ce8ad4f285d3 9 From the command-line, import the example:
seyfrid_L 0:ce8ad4f285d3 10
seyfrid_L 0:ce8ad4f285d3 11 ```
seyfrid_L 0:ce8ad4f285d3 12 mbed import mbed-os-example-blinky
seyfrid_L 0:ce8ad4f285d3 13 cd mbed-os-example-blinky
seyfrid_L 0:ce8ad4f285d3 14 ```
seyfrid_L 0:ce8ad4f285d3 15
seyfrid_L 0:ce8ad4f285d3 16 ### Now compile
seyfrid_L 0:ce8ad4f285d3 17
seyfrid_L 0:ce8ad4f285d3 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:
seyfrid_L 0:ce8ad4f285d3 19
seyfrid_L 0:ce8ad4f285d3 20 ```
seyfrid_L 0:ce8ad4f285d3 21 mbed compile -m K64F -t ARM
seyfrid_L 0:ce8ad4f285d3 22 ```
seyfrid_L 0:ce8ad4f285d3 23
seyfrid_L 0:ce8ad4f285d3 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
seyfrid_L 0:ce8ad4f285d3 25
seyfrid_L 0:ce8ad4f285d3 26 ```

seyfrid_L 0:ce8ad4f285d3 47 ### Program your board
seyfrid_L 0:ce8ad4f285d3 48
seyfrid_L 0:ce8ad4f285d3 49 1. Connect your mbed device to the computer over USB.
seyfrid_L 0:ce8ad4f285d3 50 1. Copy the binary file to the mbed device.
seyfrid_L 0:ce8ad4f285d3 51 1. Press the reset button to start the program.

seyfrid_L 0:ce8ad4f285d3 55 ## Export the project to Keil MDK, and debug your application
seyfrid_L 0:ce8ad4f285d3 56
seyfrid_L 0:ce8ad4f285d3 57 From the command-line, run the following command:
seyfrid_L 0:ce8ad4f285d3 58
seyfrid_L 0:ce8ad4f285d3 59 ```
seyfrid_L 0:ce8ad4f285d3 60 mbed export -m K64F -i uvision
seyfrid_L 0:ce8ad4f285d3 61 ```
seyfrid_L 0:ce8ad4f285d3 62
seyfrid_L 0:ce8ad4f285d3 63 To debug the application:
seyfrid_L 0:ce8ad4f285d3 64
seyfrid_L 0:ce8ad4f285d3 65 1. Start uVision.
seyfrid_L 0:ce8ad4f285d3 66 1. Import the uVision project generated earlier.
seyfrid_L 0:ce8ad4f285d3 67 1. Compile your application, and generate an `.axf` file.
seyfrid_L 0:ce8ad4f285d3 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).
seyfrid_L 0:ce8ad4f285d3 69 1. Set breakpoints, and start a debug session.

seyfrid_L 0:ce8ad4f285d3 73 ## Troubleshooting
seyfrid_L 0:ce8ad4f285d3 74
seyfrid_L 0:ce8ad4f285d3 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
seyfrid_L 0:ce8ad4f285d3 76
seyfrid_L 0:ce8ad4f285d3 77 ```
seyfrid_L 0:ce8ad4f285d3 78 mbed --version
seyfrid_L 0:ce8ad4f285d3 79 ```
seyfrid_L 0:ce8ad4f285d3 80
seyfrid_L 0:ce8ad4f285d3 81 If not, you can update it:
seyfrid_L 0:ce8ad4f285d3 82
seyfrid_L 0:ce8ad4f285d3 83 ```
seyfrid_L 0:ce8ad4f285d3 84 pip install mbed-cli --upgrade
seyfrid_L 0:ce8ad4f285d3 85 ```
seyfrid_L 0:ce8ad4f285d3 86
seyfrid_L 0:ce8ad4f285d3 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.
