agaikwad 0:92ddc9baf27b 1 # Getting started with Blinky on mbed OS
agaikwad 0:92ddc9baf27b 2
agaikwad 0:92ddc9baf27b 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
agaikwad 0:92ddc9baf27b 4
agaikwad 0:92ddc9baf27b 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
agaikwad 0:92ddc9baf27b 6
agaikwad 0:92ddc9baf27b 7 ## Import the example application
agaikwad 0:92ddc9baf27b 8
agaikwad 0:92ddc9baf27b 9 From the command-line, import the example:
agaikwad 0:92ddc9baf27b 10
agaikwad 0:92ddc9baf27b 11 ```
agaikwad 0:92ddc9baf27b 12 mbed import mbed-os-example-blinky
agaikwad 0:92ddc9baf27b 13 cd mbed-os-example-blinky
agaikwad 0:92ddc9baf27b 14 ```
agaikwad 0:92ddc9baf27b 15
agaikwad 0:92ddc9baf27b 16 ### Now compile
agaikwad 0:92ddc9baf27b 17
agaikwad 0:92ddc9baf27b 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:
agaikwad 0:92ddc9baf27b 19
agaikwad 0:92ddc9baf27b 20 ```
agaikwad 0:92ddc9baf27b 21 mbed compile -m K64F -t ARM
agaikwad 0:92ddc9baf27b 22 ```
agaikwad 0:92ddc9baf27b 23
agaikwad 0:92ddc9baf27b 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
agaikwad 0:92ddc9baf27b 25

agaikwad 0:92ddc9baf27b 47 ### Program your board
agaikwad 0:92ddc9baf27b 48
agaikwad 0:92ddc9baf27b 49 1. Connect your mbed device to the computer over USB.
agaikwad 0:92ddc9baf27b 50 1. Copy the binary file to the mbed device.
agaikwad 0:92ddc9baf27b 51 1. Press the reset button to start the program.
agaikwad 0:92ddc9baf27b 52
agaikwad 0:92ddc9baf27b 53 The LED on your platform turns on and off.

agaikwad 0:92ddc9baf27b 55 ## Export the project to Keil MDK, and debug your application
agaikwad 0:92ddc9baf27b 56
agaikwad 0:92ddc9baf27b 57 From the command-line, run the following command:
agaikwad 0:92ddc9baf27b 58
agaikwad 0:92ddc9baf27b 59 ```
agaikwad 0:92ddc9baf27b 60 mbed export -m K64F -i uvision
agaikwad 0:92ddc9baf27b 61 ```
agaikwad 0:92ddc9baf27b 62
agaikwad 0:92ddc9baf27b 63 To debug the application:
agaikwad 0:92ddc9baf27b 64
agaikwad 0:92ddc9baf27b 65 1. Start uVision.
agaikwad 0:92ddc9baf27b 66 1. Import the uVision project generated earlier.
agaikwad 0:92ddc9baf27b 67 1. Compile your application, and generate an `.axf` file.
agaikwad 0:92ddc9baf27b 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).
agaikwad 0:92ddc9baf27b 69 1. Set breakpoints, and start a debug session.

agaikwad 0:92ddc9baf27b 73 ## Troubleshooting
agaikwad 0:92ddc9baf27b 74
agaikwad 0:92ddc9baf27b 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
agaikwad 0:92ddc9baf27b 76
agaikwad 0:92ddc9baf27b 77 ```
agaikwad 0:92ddc9baf27b 78 mbed --version
agaikwad 0:92ddc9baf27b 79 ```
agaikwad 0:92ddc9baf27b 80
agaikwad 0:92ddc9baf27b 81 If not, you can update it:
agaikwad 0:92ddc9baf27b 82
agaikwad 0:92ddc9baf27b 83 ```
agaikwad 0:92ddc9baf27b 84 pip install mbed-cli --upgrade
agaikwad 0:92ddc9baf27b 85 ```
agaikwad 0:92ddc9baf27b 86
agaikwad 0:92ddc9baf27b 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.
