jacobjohnson 0:48db693b0f9e 1 # Getting started with Blinky on mbed OS
jacobjohnson 0:48db693b0f9e 2
jacobjohnson 0:48db693b0f9e 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
jacobjohnson 0:48db693b0f9e 4
jacobjohnson 0:48db693b0f9e 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
jacobjohnson 0:48db693b0f9e 6
jacobjohnson 0:48db693b0f9e 7 ## Get the example application!
jacobjohnson 0:48db693b0f9e 8
jacobjohnson 0:48db693b0f9e 9 From the command line, import the example:
jacobjohnson 0:48db693b0f9e 10
jacobjohnson 0:48db693b0f9e 11 ```
jacobjohnson 0:48db693b0f9e 12 mbed import mbed-os-example-blinky
jacobjohnson 0:48db693b0f9e 13 cd mbed-os-example-blinky
jacobjohnson 0:48db693b0f9e 14 ```
jacobjohnson 0:48db693b0f9e 15
jacobjohnson 0:48db693b0f9e 16 ### Now compile
jacobjohnson 0:48db693b0f9e 17
jacobjohnson 0:48db693b0f9e 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:
jacobjohnson 0:48db693b0f9e 19
jacobjohnson 0:48db693b0f9e 20 ```
jacobjohnson 0:48db693b0f9e 21 mbed compile -m K64F -t ARM
jacobjohnson 0:48db693b0f9e 22 ```
jacobjohnson 0:48db693b0f9e 23
jacobjohnson 0:48db693b0f9e 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
jacobjohnson 0:48db693b0f9e 25
jacobjohnson 0:48db693b0f9e 26 ```

jacobjohnson 0:48db693b0f9e 47 ### Program your board
jacobjohnson 0:48db693b0f9e 48
jacobjohnson 0:48db693b0f9e 49 1. Connect your mbed device to the computer over USB.
jacobjohnson 0:48db693b0f9e 50 1. Copy the binary file to the mbed device .
jacobjohnson 0:48db693b0f9e 51 1. Press the reset button to start the program.
jacobjohnson 0:48db693b0f9e 52
jacobjohnson 0:48db693b0f9e 53 You should see the LED of your platform turning on and off.
jacobjohnson 0:48db693b0f9e 54
jacobjohnson 0:48db693b0f9e 55 Congratulations if you managed to complete this test!

jacobjohnson 0:48db693b0f9e 57 ## Export the project to Keil MDK and debug your application
jacobjohnson 0:48db693b0f9e 58
jacobjohnson 0:48db693b0f9e 59 From the command line, run the following command:
jacobjohnson 0:48db693b0f9e 60
jacobjohnson 0:48db693b0f9e 61 ```
jacobjohnson 0:48db693b0f9e 62 mbed export -m K64F -i uvision
jacobjohnson 0:48db693b0f9e 63 ```
jacobjohnson 0:48db693b0f9e 64
jacobjohnson 0:48db693b0f9e 65 To debug the application:
jacobjohnson 0:48db693b0f9e 66
jacobjohnson 0:48db693b0f9e 67 1. Start uVision.
jacobjohnson 0:48db693b0f9e 68 1. Import the uVision project generated earlier.
jacobjohnson 0:48db693b0f9e 69 1. Compile your application and generate an `.axf` file.
jacobjohnson 0:48db693b0f9e 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).
jacobjohnson 0:48db693b0f9e 71 1. Set breakpoints and start a debug session.

jacobjohnson 0:48db693b0f9e 75 ## Troubleshooting
jacobjohnson 0:48db693b0f9e 76
jacobjohnson 0:48db693b0f9e 77 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
jacobjohnson 0:48db693b0f9e 78
jacobjohnson 0:48db693b0f9e 79 ```
jacobjohnson 0:48db693b0f9e 80 mbed --version
jacobjohnson 0:48db693b0f9e 81 ```
jacobjohnson 0:48db693b0f9e 82
jacobjohnson 0:48db693b0f9e 83 If not, you can update it easily:
jacobjohnson 0:48db693b0f9e 84
jacobjohnson 0:48db693b0f9e 85 ```
jacobjohnson 0:48db693b0f9e 86 pip install mbed-cli --upgrade
jacobjohnson 0:48db693b0f9e 87 ```
jacobjohnson 0:48db693b0f9e 88
jacobjohnson 0:48db693b0f9e 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.
