mbed_official 0:394aee574ebb 1 # Getting started with Blinky on mbed OS
mbed_official 0:394aee574ebb 2
mbed_official 0:394aee574ebb 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
mbed_official 0:394aee574ebb 4
mbed_official 0:394aee574ebb 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
mbed_official 0:394aee574ebb 6
mbed_official 0:394aee574ebb 7 ## Get the example application!
mbed_official 0:394aee574ebb 8
mbed_official 0:394aee574ebb 9 From the command line, import the example:
mbed_official 0:394aee574ebb 10
mbed_official 0:394aee574ebb 11 ```
mbed_official 0:394aee574ebb 12 mbed import mbed-os-example-blinky
mbed_official 0:394aee574ebb 13 cd mbed-os-example-blinky
mbed_official 0:394aee574ebb 14 ```
mbed_official 0:394aee574ebb 15
mbed_official 0:394aee574ebb 16 ### Now compile
mbed_official 0:394aee574ebb 17
mbed_official 0:394aee574ebb 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:
mbed_official 0:394aee574ebb 19
mbed_official 0:394aee574ebb 20 ```
mbed_official 0:394aee574ebb 21 mbed compile -m K64F -t ARM
mbed_official 0:394aee574ebb 22 ```
mbed_official 0:394aee574ebb 23
mbed_official 0:394aee574ebb 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
mbed_official 0:394aee574ebb 25
mbed_official 0:394aee574ebb 26 ```

mbed_official 0:394aee574ebb 57 ## Export the project to Keil MDK and debug your application
mbed_official 0:394aee574ebb 58
mbed_official 0:394aee574ebb 59 From the command line, run the following command:
mbed_official 0:394aee574ebb 60
mbed_official 0:394aee574ebb 61 ```
mbed_official 0:394aee574ebb 62 mbed export -m K64F -i uvision
mbed_official 0:394aee574ebb 63 ```
mbed_official 0:394aee574ebb 64
mbed_official 0:394aee574ebb 65 To debug the application:
mbed_official 0:394aee574ebb 66
mbed_official 0:394aee574ebb 67 1. Start uVision.
mbed_official 0:394aee574ebb 68 1. Import the uVision project generated earlier.
mbed_official 0:394aee574ebb 69 1. Compile your application and generate an `.axf` file.
mbed_official 0:394aee574ebb 70 1. Make sure uVision is configured to debug over CMSIS-DAP (From the Project menu > Options for Target '...' > Debug tab > Use CMSIS-DAP Debugger).
mbed_official 0:394aee574ebb 71 1. Set breakpoints and start a debug session.

mbed_official 0:394aee574ebb 75 ## Troubleshooting
mbed_official 0:394aee574ebb 76
mbed_official 0:394aee574ebb 77 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
mbed_official 0:394aee574ebb 78
mbed_official 0:394aee574ebb 79 ```
mbed_official 0:394aee574ebb 80 mbed --version
mbed_official 0:394aee574ebb 81 ```
mbed_official 0:394aee574ebb 82
mbed_official 0:394aee574ebb 83 If not, you can update it easily:
mbed_official 0:394aee574ebb 84
mbed_official 0:394aee574ebb 85 ```
mbed_official 0:394aee574ebb 86 pip install mbed-cli --upgrade
mbed_official 0:394aee574ebb 87 ```
mbed_official 0:394aee574ebb 88
mbed_official 0:394aee574ebb 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.
