gkroussos 0:774078f45f9d 1 # Getting started with Blinky on mbed OS
gkroussos 0:774078f45f9d 2
gkroussos 0:774078f45f9d 3 This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform.
gkroussos 0:774078f45f9d 4
gkroussos 0:774078f45f9d 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
gkroussos 0:774078f45f9d 6
gkroussos 0:774078f45f9d 7 ## Get the example application!
gkroussos 0:774078f45f9d 8
gkroussos 0:774078f45f9d 9 From the command line, import the example:
gkroussos 0:774078f45f9d 10
gkroussos 0:774078f45f9d 11 ```
gkroussos 0:774078f45f9d 12 mbed import mbed-os-example-blinky
gkroussos 0:774078f45f9d 13 cd mbed-os-example-blinky
gkroussos 0:774078f45f9d 14 ```
gkroussos 0:774078f45f9d 15
gkroussos 0:774078f45f9d 16 ### Now compile
gkroussos 0:774078f45f9d 17
gkroussos 0:774078f45f9d 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:
gkroussos 0:774078f45f9d 19
gkroussos 0:774078f45f9d 20 ```
gkroussos 0:774078f45f9d 21 mbed compile -m K64F -t ARM
gkroussos 0:774078f45f9d 22 ```
gkroussos 0:774078f45f9d 23
gkroussos 0:774078f45f9d 24 Your PC may take a few minutes to compile your code. At the end you should get the following result:
gkroussos 0:774078f45f9d 25
gkroussos 0:774078f45f9d 26 ```

gkroussos 0:774078f45f9d 57 ## Export the project to Keil MDK and debug your application
gkroussos 0:774078f45f9d 58
gkroussos 0:774078f45f9d 59 From the command line, run the following command:
gkroussos 0:774078f45f9d 60
gkroussos 0:774078f45f9d 61 ```

gkroussos 0:774078f45f9d 63 ```
gkroussos 0:774078f45f9d 64
gkroussos 0:774078f45f9d 65 To debug the application:
gkroussos 0:774078f45f9d 66
gkroussos 0:774078f45f9d 67 1. Start uVision.
gkroussos 0:774078f45f9d 68 1. Import the uVision project generated earlier.
gkroussos 0:774078f45f9d 69 1. Compile your application and generate an `.axf` file.
gkroussos 0:774078f45f9d 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).

gkroussos 0:774078f45f9d 75 ## Troubleshooting
gkroussos 0:774078f45f9d 76
gkroussos 0:774078f45f9d 77 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9`
gkroussos 0:774078f45f9d 78
gkroussos 0:774078f45f9d 79 ```
gkroussos 0:774078f45f9d 80 mbed --version
gkroussos 0:774078f45f9d 81 ```
gkroussos 0:774078f45f9d 82
gkroussos 0:774078f45f9d 83 If not, you can update it easily:
gkroussos 0:774078f45f9d 84
gkroussos 0:774078f45f9d 85 ```
gkroussos 0:774078f45f9d 86 pip install mbed-cli --upgrade
gkroussos 0:774078f45f9d 87 ```
gkroussos 0:774078f45f9d 88
gkroussos 0:774078f45f9d 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.
