khuang 0:64580390e64a 1 # Getting started with Blinky on mbed OS
khuang 0:64580390e64a 2
khuang 0:64580390e64a 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
khuang 0:64580390e64a 4
khuang 0:64580390e64a 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
khuang 0:64580390e64a 6
khuang 0:64580390e64a 7 ## Get the example application!
khuang 0:64580390e64a 8
khuang 0:64580390e64a 9 From the command line, import the example:
khuang 0:64580390e64a 10
khuang 0:64580390e64a 11 ```
khuang 0:64580390e64a 12 mbed import mbed-os-example-blinky
khuang 0:64580390e64a 13 cd mbed-os-example-blinky
khuang 0:64580390e64a 14 ```
khuang 0:64580390e64a 15
khuang 0:64580390e64a 16 ### Now compile
khuang 0:64580390e64a 17
khuang 0:64580390e64a 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:
khuang 0:64580390e64a 19
khuang 0:64580390e64a 20 ```
khuang 0:64580390e64a 21 mbed compile -m K64F -t ARM
khuang 0:64580390e64a 22 ```
khuang 0:64580390e64a 23
khuang 0:64580390e64a 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
khuang 0:64580390e64a 25
khuang 0:64580390e64a 26 ```

khuang 0:64580390e64a 47 ### Program your board
khuang 0:64580390e64a 48
khuang 0:64580390e64a 49 1. Connect your mbed device to the computer over USB.
khuang 0:64580390e64a 50 1. Copy the binary file to the mbed device .
khuang 0:64580390e64a 51 1. Press the reset button to start the program.
khuang 0:64580390e64a 52
khuang 0:64580390e64a 53 You should see the LED of your platform turning on and off.
khuang 0:64580390e64a 54
khuang 0:64580390e64a 55 Congratulations if you managed to complete this test!

khuang 0:64580390e64a 57 ## Export the project to Keil MDK and debug your application
khuang 0:64580390e64a 58
khuang 0:64580390e64a 59 From the command line, run the following command:
khuang 0:64580390e64a 60
khuang 0:64580390e64a 61 ```
khuang 0:64580390e64a 62 mbed export -m K64F -i uvision
khuang 0:64580390e64a 63 ```
khuang 0:64580390e64a 64
khuang 0:64580390e64a 65 You should see the following output:
khuang 0:64580390e64a 66
khuang 0:64580390e64a 67 ```
khuang 0:64580390e64a 68 Successful exports:
khuang 0:64580390e64a 69 * K64F::uvision .\projectfiles\uvision_K64F\Unnamed_Project
khuang 0:64580390e64a 70 ```
khuang 0:64580390e64a 71
khuang 0:64580390e64a 72 To debug the application:
khuang 0:64580390e64a 73
khuang 0:64580390e64a 74 1. Start uVision.
khuang 0:64580390e64a 75 1. Import the uVision project generated earlier.
khuang 0:64580390e64a 76 1. Compile your application and generate an `.axf` file.
khuang 0:64580390e64a 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).
khuang 0:64580390e64a 78 1. Set breakpoints and start a debug session.

khuang 0:64580390e64a 82 ## Troubleshooting
khuang 0:64580390e64a 83
khuang 0:64580390e64a 84 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
khuang 0:64580390e64a 85
khuang 0:64580390e64a 86 ```
khuang 0:64580390e64a 87 mbed --version
khuang 0:64580390e64a 88 ```
khuang 0:64580390e64a 89
khuang 0:64580390e64a 90 If not, you can update it easily:
khuang 0:64580390e64a 91
khuang 0:64580390e64a 92 ```
khuang 0:64580390e64a 93 pip install mbed-cli --upgrade
khuang 0:64580390e64a 94 ```
khuang 0:64580390e64a 95
khuang 0:64580390e64a 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.
