co657_frmb 0:f4e27396137e 1 # Getting started with Blinky on mbed OS
co657_frmb 0:f4e27396137e 2
co657_frmb 0:f4e27396137e 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
co657_frmb 0:f4e27396137e 4
co657_frmb 0:f4e27396137e 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
co657_frmb 0:f4e27396137e 6
co657_frmb 0:f4e27396137e 7 ## Get the example application!
co657_frmb 0:f4e27396137e 8
co657_frmb 0:f4e27396137e 9 From the command line, import the example:
co657_frmb 0:f4e27396137e 10
co657_frmb 0:f4e27396137e 11 ```
co657_frmb 0:f4e27396137e 12 mbed import mbed-os-example-blinky
co657_frmb 0:f4e27396137e 13 cd mbed-os-example-blinky
co657_frmb 0:f4e27396137e 14 ```
co657_frmb 0:f4e27396137e 15
co657_frmb 0:f4e27396137e 16 ### Now compile
co657_frmb 0:f4e27396137e 17
co657_frmb 0:f4e27396137e 18 Invoke `mbed compile` specifying the name of your platform and your favorite toolchain (`GCC_ARM`, `ARM`, `IAR`). For example, for the ARM Compiler 5:
co657_frmb 0:f4e27396137e 19
co657_frmb 0:f4e27396137e 20 ```
co657_frmb 0:f4e27396137e 21 mbed compile -m K64F -t ARM
co657_frmb 0:f4e27396137e 22 ```
co657_frmb 0:f4e27396137e 23
co657_frmb 0:f4e27396137e 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
co657_frmb 0:f4e27396137e 25
co657_frmb 0:f4e27396137e 26 ```

co657_frmb 0:f4e27396137e 47 ### Program your board
co657_frmb 0:f4e27396137e 48
co657_frmb 0:f4e27396137e 49 1. Connect your mbed device to the computer over USB.
co657_frmb 0:f4e27396137e 50 1. Copy the binary file to the mbed device .
co657_frmb 0:f4e27396137e 51 1. Press the reset button to start the program.
co657_frmb 0:f4e27396137e 52

co657_frmb 0:f4e27396137e 57 ## Export the project to Keil MDK and debug your application
co657_frmb 0:f4e27396137e 58
co657_frmb 0:f4e27396137e 59 From the command line, run the following command:
co657_frmb 0:f4e27396137e 60
co657_frmb 0:f4e27396137e 61 ```
co657_frmb 0:f4e27396137e 62 mbed export -m K64F -i uvision
co657_frmb 0:f4e27396137e 63 ```
co657_frmb 0:f4e27396137e 64
co657_frmb 0:f4e27396137e 65 To debug the application:
co657_frmb 0:f4e27396137e 66
co657_frmb 0:f4e27396137e 67 1. Start uVision.

co657_frmb 0:f4e27396137e 75 ## Troubleshooting
co657_frmb 0:f4e27396137e 76
co657_frmb 0:f4e27396137e 77 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
co657_frmb 0:f4e27396137e 78
co657_frmb 0:f4e27396137e 79 ```
co657_frmb 0:f4e27396137e 80 mbed --version
co657_frmb 0:f4e27396137e 81 ```
co657_frmb 0:f4e27396137e 82
co657_frmb 0:f4e27396137e 83 If not, you can update it easily:
co657_frmb 0:f4e27396137e 84
co657_frmb 0:f4e27396137e 85 ```
co657_frmb 0:f4e27396137e 86 pip install mbed-cli --upgrade
co657_frmb 0:f4e27396137e 87 ```
co657_frmb 0:f4e27396137e 88
co657_frmb 0:f4e27396137e 89 2. If using Keil MDK, make sure you have a license installed. [MDK-Lite](http://www.keil.com/arm/mdk.asp) has a 32KB restriction on code size.
