Jonathan Austin 0:2757d7abb7d9 1 # Getting started with Blinky on mbed OS
Jonathan Austin 0:2757d7abb7d9 2
Jonathan Austin 0:2757d7abb7d9 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
Jonathan Austin 0:2757d7abb7d9 4
Jonathan Austin 0:2757d7abb7d9 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
Jonathan Austin 0:2757d7abb7d9 6
Jonathan Austin 0:2757d7abb7d9 7 ## Get the example application!
Jonathan Austin 0:2757d7abb7d9 8
Jonathan Austin 0:2757d7abb7d9 9 From the command line, import the example:
Jonathan Austin 0:2757d7abb7d9 10
Jonathan Austin 0:2757d7abb7d9 11 ```
Jonathan Austin 0:2757d7abb7d9 12 mbed import mbed-os-example-blinky
Jonathan Austin 0:2757d7abb7d9 13 cd mbed-os-example-blinky
Jonathan Austin 0:2757d7abb7d9 14 ```
Jonathan Austin 0:2757d7abb7d9 15
Jonathan Austin 0:2757d7abb7d9 16 ### Now compile
Jonathan Austin 0:2757d7abb7d9 17
Jonathan Austin 0:2757d7abb7d9 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:
Jonathan Austin 0:2757d7abb7d9 19
Jonathan Austin 0:2757d7abb7d9 20 ```
Jonathan Austin 0:2757d7abb7d9 21 mbed compile -m K64F -t ARM
Jonathan Austin 0:2757d7abb7d9 22 ```
Jonathan Austin 0:2757d7abb7d9 23
Jonathan Austin 0:2757d7abb7d9 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
Jonathan Austin 0:2757d7abb7d9 25
Jonathan Austin 0:2757d7abb7d9 26 ```

Jonathan Austin 0:2757d7abb7d9 47 ### Program your board
Jonathan Austin 0:2757d7abb7d9 48
Jonathan Austin 0:2757d7abb7d9 49 1. Connect your mbed device to the computer over USB.
Jonathan Austin 0:2757d7abb7d9 50 1. Copy the binary file to the mbed device .
Jonathan Austin 0:2757d7abb7d9 51 1. Press the reset button to start the program.
Jonathan Austin 0:2757d7abb7d9 52
Jonathan Austin 0:2757d7abb7d9 53 You should see the LED of your platform turning on and off.

Jonathan Austin 0:2757d7abb7d9 57 ## Export the project to Keil MDK and debug your application
Jonathan Austin 0:2757d7abb7d9 58
Jonathan Austin 0:2757d7abb7d9 59 From the command line, run the following command:
Jonathan Austin 0:2757d7abb7d9 60
Jonathan Austin 0:2757d7abb7d9 61 ```
Jonathan Austin 1:846c97078558 62 mbed export -m K64F -i uvision
Jonathan Austin 0:2757d7abb7d9 63 ```
Jonathan Austin 0:2757d7abb7d9 64
Jonathan Austin 0:2757d7abb7d9 65 You should see the following output:
Jonathan Austin 0:2757d7abb7d9 66
Jonathan Austin 0:2757d7abb7d9 67 ```
Jonathan Austin 0:2757d7abb7d9 68 Successful exports:
Jonathan Austin 0:2757d7abb7d9 69 * K64F::uvision .\projectfiles\uvision_K64F\mbed-os-example-blinky
Jonathan Austin 0:2757d7abb7d9 70 ```
Jonathan Austin 0:2757d7abb7d9 71
Jonathan Austin 0:2757d7abb7d9 72 To debug the application:
Jonathan Austin 0:2757d7abb7d9 73
Jonathan Austin 0:2757d7abb7d9 74 1. Start uVision.
Jonathan Austin 0:2757d7abb7d9 75 1. Import the uVision project generated earlier.
Jonathan Austin 0:2757d7abb7d9 76 1. Compile your application and generate an `.axf` file.
Jonathan Austin 0:2757d7abb7d9 77 1. Make sure uVision is configured to debug over CMSIS-DAP (From the Project menu > Options for Target '...' > Debug tab > Use CMSIS-DAP Debugger).
Jonathan Austin 0:2757d7abb7d9 78 1. Set breakpoints and start a debug session.

Jonathan Austin 0:2757d7abb7d9 82 ## Troubleshooting
Jonathan Austin 0:2757d7abb7d9 83
Jonathan Austin 0:2757d7abb7d9 84 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.0`
Jonathan Austin 0:2757d7abb7d9 85
Jonathan Austin 0:2757d7abb7d9 86 ```
Jonathan Austin 0:2757d7abb7d9 87 mbed --version
Jonathan Austin 0:2757d7abb7d9 88 ```
Jonathan Austin 0:2757d7abb7d9 89
Jonathan Austin 0:2757d7abb7d9 90 If not, you can update it easily:
Jonathan Austin 0:2757d7abb7d9 91
Jonathan Austin 0:2757d7abb7d9 92 ```
Jonathan Austin 0:2757d7abb7d9 93 pip install mbed-cli --upgrade
Jonathan Austin 0:2757d7abb7d9 94 ```
Jonathan Austin 0:2757d7abb7d9 95
Jonathan Austin 0:2757d7abb7d9 96 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.
