joschaihl 0:2e946c38e476 1 # Getting started with Blinky on mbed OS
joschaihl 0:2e946c38e476 2
joschaihl 0:2e946c38e476 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
joschaihl 0:2e946c38e476 4
joschaihl 0:2e946c38e476 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
joschaihl 0:2e946c38e476 6
joschaihl 0:2e946c38e476 7 ## Import the example application
joschaihl 0:2e946c38e476 8
joschaihl 0:2e946c38e476 9 From the command-line, import the example:
joschaihl 0:2e946c38e476 10
joschaihl 0:2e946c38e476 11 ```
joschaihl 0:2e946c38e476 12 mbed import mbed-os-example-blinky
joschaihl 0:2e946c38e476 13 cd mbed-os-example-blinky
joschaihl 0:2e946c38e476 14 ```
joschaihl 0:2e946c38e476 15
joschaihl 0:2e946c38e476 16 ### Now compile
joschaihl 0:2e946c38e476 17
joschaihl 0:2e946c38e476 18 Invoke `mbed compile`, and specify the name of your platform and your favorite toolchain (`GCC_ARM`, `ARM`, `IAR`). For example, for the ARM Compiler 5:
joschaihl 0:2e946c38e476 19
joschaihl 0:2e946c38e476 20 ```
joschaihl 0:2e946c38e476 21 mbed compile -m K64F -t ARM
joschaihl 0:2e946c38e476 22 ```
joschaihl 0:2e946c38e476 23
joschaihl 0:2e946c38e476 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
joschaihl 0:2e946c38e476 25
joschaihl 0:2e946c38e476 26 ```

joschaihl 0:2e946c38e476 47 ### Program your board
joschaihl 0:2e946c38e476 48
joschaihl 0:2e946c38e476 49 1. Connect your mbed device to the computer over USB.
joschaihl 0:2e946c38e476 50 1. Copy the binary file to the mbed device.
joschaihl 0:2e946c38e476 51 1. Press the reset button to start the program.

joschaihl 0:2e946c38e476 55 ## Export the project to Keil MDK, and debug your application
joschaihl 0:2e946c38e476 56
joschaihl 0:2e946c38e476 57 From the command-line, run the following command:
joschaihl 0:2e946c38e476 58
joschaihl 0:2e946c38e476 59 ```
joschaihl 0:2e946c38e476 60 mbed export -m K64F -i uvision
joschaihl 0:2e946c38e476 61 ```
joschaihl 0:2e946c38e476 62
joschaihl 0:2e946c38e476 63 To debug the application:
joschaihl 0:2e946c38e476 64
joschaihl 0:2e946c38e476 65 1. Start uVision.
joschaihl 0:2e946c38e476 66 1. Import the uVision project generated earlier.
joschaihl 0:2e946c38e476 67 1. Compile your application, and generate an `.axf` file.
joschaihl 0:2e946c38e476 68 1. Make sure uVision is configured to debug over CMSIS-DAP (From the Project menu > Options for Target '...' > Debug tab > Use CMSIS-DAP Debugger).
joschaihl 0:2e946c38e476 69 1. Set breakpoints, and start a debug session.

joschaihl 0:2e946c38e476 73 ## Troubleshooting
joschaihl 0:2e946c38e476 74
joschaihl 0:2e946c38e476 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
joschaihl 0:2e946c38e476 76
joschaihl 0:2e946c38e476 77 ```
joschaihl 0:2e946c38e476 78 mbed --version
joschaihl 0:2e946c38e476 79 ```
joschaihl 0:2e946c38e476 80
joschaihl 0:2e946c38e476 81 If not, you can update it:
joschaihl 0:2e946c38e476 82
joschaihl 0:2e946c38e476 83 ```
joschaihl 0:2e946c38e476 84 pip install mbed-cli --upgrade
joschaihl 0:2e946c38e476 85 ```
joschaihl 0:2e946c38e476 86
joschaihl 0:2e946c38e476 87 2. If using Keil MDK, make sure you have a license installed. [MDK-Lite](http://www.keil.com/arm/mdk.asp) has a 32 KB restriction on code size.
