noutram 0:9ff439f5bf2e 1 # Getting started with Blinky on mbed OS
noutram 0:9ff439f5bf2e 2
noutram 0:9ff439f5bf2e 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
noutram 0:9ff439f5bf2e 4
noutram 0:9ff439f5bf2e 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
noutram 0:9ff439f5bf2e 6
noutram 0:9ff439f5bf2e 7 ## Import the example application
noutram 0:9ff439f5bf2e 8
noutram 0:9ff439f5bf2e 9 From the command-line, import the example:
noutram 0:9ff439f5bf2e 10
noutram 0:9ff439f5bf2e 11 ```
noutram 0:9ff439f5bf2e 12 mbed import mbed-os-example-blinky
noutram 0:9ff439f5bf2e 13 cd mbed-os-example-blinky
noutram 0:9ff439f5bf2e 14 ```
noutram 0:9ff439f5bf2e 15
noutram 0:9ff439f5bf2e 16 ### Now compile
noutram 0:9ff439f5bf2e 17
noutram 0:9ff439f5bf2e 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 0:9ff439f5bf2e 19
noutram 0:9ff439f5bf2e 20 ```
noutram 0:9ff439f5bf2e 21 mbed compile -m K64F -t ARM
noutram 0:9ff439f5bf2e 22 ```
noutram 0:9ff439f5bf2e 23
noutram 0:9ff439f5bf2e 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
noutram 0:9ff439f5bf2e 25
noutram 0:9ff439f5bf2e 26 ```

noutram 0:9ff439f5bf2e 47 ### Program your board
noutram 0:9ff439f5bf2e 48
noutram 0:9ff439f5bf2e 49 1. Connect your mbed device to the computer over USB.
noutram 0:9ff439f5bf2e 50 1. Copy the binary file to the mbed device.
noutram 0:9ff439f5bf2e 51 1. Press the reset button to start the program.
noutram 0:9ff439f5bf2e 52
noutram 0:9ff439f5bf2e 53 The LED on your platform turns on and off.
noutram 0:9ff439f5bf2e 54
noutram 0:9ff439f5bf2e 55 ## Export the project to Keil MDK, and debug your application
noutram 0:9ff439f5bf2e 56
noutram 0:9ff439f5bf2e 57 From the command-line, run the following command:
noutram 0:9ff439f5bf2e 58
noutram 0:9ff439f5bf2e 59 ```
noutram 0:9ff439f5bf2e 60 mbed export -m K64F -i uvision
noutram 0:9ff439f5bf2e 61 ```
noutram 0:9ff439f5bf2e 62
noutram 0:9ff439f5bf2e 63 To debug the application:
noutram 0:9ff439f5bf2e 64
noutram 0:9ff439f5bf2e 65 1. Start uVision.
noutram 0:9ff439f5bf2e 66 1. Import the uVision project generated earlier.
noutram 0:9ff439f5bf2e 67 1. Compile your application, and generate an `.axf` file.
noutram 0:9ff439f5bf2e 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 0:9ff439f5bf2e 69 1. Set breakpoints, and start a debug session.

noutram 0:9ff439f5bf2e 73 ## Troubleshooting
noutram 0:9ff439f5bf2e 74
noutram 0:9ff439f5bf2e 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
noutram 0:9ff439f5bf2e 76
noutram 0:9ff439f5bf2e 77 ```
noutram 0:9ff439f5bf2e 78 mbed --version
noutram 0:9ff439f5bf2e 79 ```
noutram 0:9ff439f5bf2e 80
noutram 0:9ff439f5bf2e 81 If not, you can update it:
noutram 0:9ff439f5bf2e 82
noutram 0:9ff439f5bf2e 83 ```
noutram 0:9ff439f5bf2e 84 pip install mbed-cli --upgrade
noutram 0:9ff439f5bf2e 85 ```
noutram 0:9ff439f5bf2e 86
noutram 0:9ff439f5bf2e 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.
