jacobjohnson 0:8fbbced097c5 1 # Getting started with Blinky on mbed OS
jacobjohnson 0:8fbbced097c5 2
jacobjohnson 0:8fbbced097c5 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
jacobjohnson 0:8fbbced097c5 4
jacobjohnson 0:8fbbced097c5 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
jacobjohnson 0:8fbbced097c5 6
jacobjohnson 0:8fbbced097c5 7 ## Get the example application!
jacobjohnson 0:8fbbced097c5 8
jacobjohnson 0:8fbbced097c5 9 From the command line, import the example:
jacobjohnson 0:8fbbced097c5 10
jacobjohnson 0:8fbbced097c5 11 ```
jacobjohnson 0:8fbbced097c5 12 mbed import mbed-os-example-blinky
jacobjohnson 0:8fbbced097c5 13 cd mbed-os-example-blinky
jacobjohnson 0:8fbbced097c5 14 ```
jacobjohnson 0:8fbbced097c5 15
jacobjohnson 0:8fbbced097c5 16 ### Now compile
jacobjohnson 0:8fbbced097c5 17
jacobjohnson 0:8fbbced097c5 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 0:8fbbced097c5 19
jacobjohnson 0:8fbbced097c5 20 ```
jacobjohnson 0:8fbbced097c5 21 mbed compile -m K64F -t ARM
jacobjohnson 0:8fbbced097c5 22 ```
jacobjohnson 0:8fbbced097c5 23
jacobjohnson 0:8fbbced097c5 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
jacobjohnson 0:8fbbced097c5 25

jacobjohnson 0:8fbbced097c5 47 ### Program your board
jacobjohnson 0:8fbbced097c5 48
jacobjohnson 0:8fbbced097c5 49 1. Connect your mbed device to the computer over USB.
jacobjohnson 0:8fbbced097c5 50 1. Copy the binary file to the mbed device .
jacobjohnson 0:8fbbced097c5 51 1. Press the reset button to start the program.
jacobjohnson 0:8fbbced097c5 52
jacobjohnson 0:8fbbced097c5 53 You should see the LED of your platform turning on and off.
jacobjohnson 0:8fbbced097c5 54
jacobjohnson 0:8fbbced097c5 55 Congratulations if you managed to complete this test!

jacobjohnson 0:8fbbced097c5 57 ## Export the project to Keil MDK and debug your application
jacobjohnson 0:8fbbced097c5 58
jacobjohnson 0:8fbbced097c5 59 From the command line, run the following command:
jacobjohnson 0:8fbbced097c5 60
jacobjohnson 0:8fbbced097c5 61 ```
jacobjohnson 0:8fbbced097c5 62 mbed export -m K64F -i uvision
jacobjohnson 0:8fbbced097c5 63 ```
jacobjohnson 0:8fbbced097c5 64
jacobjohnson 0:8fbbced097c5 65 To debug the application:
jacobjohnson 0:8fbbced097c5 66
jacobjohnson 0:8fbbced097c5 67 1. Start uVision.
jacobjohnson 0:8fbbced097c5 68 1. Import the uVision project generated earlier.
jacobjohnson 0:8fbbced097c5 69 1. Compile your application and generate an `.axf` file.
jacobjohnson 0:8fbbced097c5 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 0:8fbbced097c5 71 1. Set breakpoints and start a debug session.

jacobjohnson 0:8fbbced097c5 75 ## Troubleshooting
jacobjohnson 0:8fbbced097c5 76
jacobjohnson 0:8fbbced097c5 77 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
jacobjohnson 0:8fbbced097c5 78
jacobjohnson 0:8fbbced097c5 79 ```
jacobjohnson 0:8fbbced097c5 80 mbed --version
jacobjohnson 0:8fbbced097c5 81 ```
jacobjohnson 0:8fbbced097c5 82
jacobjohnson 0:8fbbced097c5 83 If not, you can update it easily:
jacobjohnson 0:8fbbced097c5 84
jacobjohnson 0:8fbbced097c5 85 ```
jacobjohnson 0:8fbbced097c5 86 pip install mbed-cli --upgrade
jacobjohnson 0:8fbbced097c5 87 ```
jacobjohnson 0:8fbbced097c5 88
jacobjohnson 0:8fbbced097c5 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.
