tbotsQ 0:08d373203e2e 1 # Getting started with Blinky on mbed OS
tbotsQ 0:08d373203e2e 2
tbotsQ 0:08d373203e2e 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
tbotsQ 0:08d373203e2e 4
tbotsQ 0:08d373203e2e 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
tbotsQ 0:08d373203e2e 6
tbotsQ 0:08d373203e2e 7 ## Get the example application!
tbotsQ 0:08d373203e2e 8
tbotsQ 0:08d373203e2e 9 From the command line, import the example:
tbotsQ 0:08d373203e2e 10
tbotsQ 0:08d373203e2e 11 ```
tbotsQ 0:08d373203e2e 12 mbed import mbed-os-example-blinky
tbotsQ 0:08d373203e2e 13 cd mbed-os-example-blinky
tbotsQ 0:08d373203e2e 14 ```
tbotsQ 0:08d373203e2e 15
tbotsQ 0:08d373203e2e 16 ### Now compile
tbotsQ 0:08d373203e2e 17
tbotsQ 0:08d373203e2e 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:
tbotsQ 0:08d373203e2e 19
tbotsQ 0:08d373203e2e 20 ```
tbotsQ 0:08d373203e2e 21 mbed compile -m K64F -t ARM
tbotsQ 0:08d373203e2e 22 ```
tbotsQ 0:08d373203e2e 23
tbotsQ 0:08d373203e2e 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
tbotsQ 0:08d373203e2e 25
tbotsQ 0:08d373203e2e 26 ```

tbotsQ 0:08d373203e2e 47 ### Program your board
tbotsQ 0:08d373203e2e 48
tbotsQ 0:08d373203e2e 49 1. Connect your mbed device to the computer over USB.
tbotsQ 0:08d373203e2e 50 1. Copy the binary file to the mbed device .
tbotsQ 0:08d373203e2e 51 1. Press the reset button to start the program.
tbotsQ 0:08d373203e2e 52
tbotsQ 0:08d373203e2e 53 You should see the LED of your platform turning on and off.

tbotsQ 0:08d373203e2e 57 ## Export the project to Keil MDK and debug your application
tbotsQ 0:08d373203e2e 58
tbotsQ 0:08d373203e2e 59 From the command line, run the following command:
tbotsQ 0:08d373203e2e 60
tbotsQ 0:08d373203e2e 61 ```
tbotsQ 0:08d373203e2e 62 mbed export -m K64F -i uvision
tbotsQ 0:08d373203e2e 63 ```
tbotsQ 0:08d373203e2e 64
tbotsQ 0:08d373203e2e 65 To debug the application:
tbotsQ 0:08d373203e2e 66
tbotsQ 0:08d373203e2e 67 1. Start uVision.
tbotsQ 0:08d373203e2e 68 1. Import the uVision project generated earlier.
tbotsQ 0:08d373203e2e 69 1. Compile your application and generate an `.axf` file.
tbotsQ 0:08d373203e2e 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).
tbotsQ 0:08d373203e2e 71 1. Set breakpoints and start a debug session.

tbotsQ 0:08d373203e2e 75 ## Troubleshooting
tbotsQ 0:08d373203e2e 76
tbotsQ 0:08d373203e2e 77 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
tbotsQ 0:08d373203e2e 78
tbotsQ 0:08d373203e2e 79 ```
tbotsQ 0:08d373203e2e 80 mbed --version
tbotsQ 0:08d373203e2e 81 ```
tbotsQ 0:08d373203e2e 82
tbotsQ 0:08d373203e2e 83 If not, you can update it easily:
tbotsQ 0:08d373203e2e 84
tbotsQ 0:08d373203e2e 85 ```
tbotsQ 0:08d373203e2e 86 pip install mbed-cli --upgrade
tbotsQ 0:08d373203e2e 87 ```
tbotsQ 0:08d373203e2e 88
tbotsQ 0:08d373203e2e 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.
