renangueiros 0:6ca395acc2a5 1 # Getting started with Blinky on mbed OS
renangueiros 0:6ca395acc2a5 2
renangueiros 0:6ca395acc2a5 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
renangueiros 0:6ca395acc2a5 4
renangueiros 0:6ca395acc2a5 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
renangueiros 0:6ca395acc2a5 6
renangueiros 0:6ca395acc2a5 7 ## Get the example application!
renangueiros 0:6ca395acc2a5 8
renangueiros 0:6ca395acc2a5 9 From the command line, import the example:
renangueiros 0:6ca395acc2a5 10
renangueiros 0:6ca395acc2a5 11 ```
renangueiros 0:6ca395acc2a5 12 mbed import mbed-os-example-blinky
renangueiros 0:6ca395acc2a5 13 cd mbed-os-example-blinky
renangueiros 0:6ca395acc2a5 14 ```
renangueiros 0:6ca395acc2a5 15
renangueiros 0:6ca395acc2a5 16 ### Now compile
renangueiros 0:6ca395acc2a5 17
renangueiros 0:6ca395acc2a5 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:
renangueiros 0:6ca395acc2a5 19
renangueiros 0:6ca395acc2a5 20 ```
renangueiros 0:6ca395acc2a5 21 mbed compile -m K64F -t ARM
renangueiros 0:6ca395acc2a5 22 ```
renangueiros 0:6ca395acc2a5 23
renangueiros 0:6ca395acc2a5 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
renangueiros 0:6ca395acc2a5 25
renangueiros 0:6ca395acc2a5 26 ```

renangueiros 0:6ca395acc2a5 47 ### Program your board
renangueiros 0:6ca395acc2a5 48
renangueiros 0:6ca395acc2a5 49 1. Connect your mbed device to the computer over USB.
renangueiros 0:6ca395acc2a5 50 1. Copy the binary file to the mbed device .
renangueiros 0:6ca395acc2a5 51 1. Press the reset button to start the program.
renangueiros 0:6ca395acc2a5 52
renangueiros 0:6ca395acc2a5 53 You should see the LED of your platform turning on and off.
renangueiros 0:6ca395acc2a5 54
renangueiros 0:6ca395acc2a5 55 Congratulations if you managed to complete this test!
renangueiros 0:6ca395acc2a5 56
renangueiros 0:6ca395acc2a5 57 ## Export the project to Keil MDK and debug your application
renangueiros 0:6ca395acc2a5 58
renangueiros 0:6ca395acc2a5 59 From the command line, run the following command:
renangueiros 0:6ca395acc2a5 60
renangueiros 0:6ca395acc2a5 61 ```
renangueiros 0:6ca395acc2a5 62 mbed export -m K64F -i uvision
renangueiros 0:6ca395acc2a5 63 ```
renangueiros 0:6ca395acc2a5 64
renangueiros 0:6ca395acc2a5 65 To debug the application:
renangueiros 0:6ca395acc2a5 66
renangueiros 0:6ca395acc2a5 67 1. Start uVision.
renangueiros 0:6ca395acc2a5 68 1. Import the uVision project generated earlier.
renangueiros 0:6ca395acc2a5 69 1. Compile your application and generate an `.axf` file.
renangueiros 0:6ca395acc2a5 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).
renangueiros 0:6ca395acc2a5 71 1. Set breakpoints and start a debug session.

renangueiros 0:6ca395acc2a5 74
renangueiros 0:6ca395acc2a5 75 ## Troubleshooting
renangueiros 0:6ca395acc2a5 76
renangueiros 0:6ca395acc2a5 77 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
renangueiros 0:6ca395acc2a5 78
renangueiros 0:6ca395acc2a5 79 ```
renangueiros 0:6ca395acc2a5 80 mbed --version
renangueiros 0:6ca395acc2a5 81 ```
renangueiros 0:6ca395acc2a5 82
renangueiros 0:6ca395acc2a5 83 If not, you can update it easily:
renangueiros 0:6ca395acc2a5 84
renangueiros 0:6ca395acc2a5 85 ```
renangueiros 0:6ca395acc2a5 86 pip install mbed-cli --upgrade
renangueiros 0:6ca395acc2a5 87 ```
renangueiros 0:6ca395acc2a5 88
renangueiros 0:6ca395acc2a5 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.
