# Getting started with Blinky on mbed OS This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform. Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli). ## Get the example application! From the command line, import the example: ``` mbed import mbed-os-example-blinky cd mbed-os-example-blinky ``` ### Now compile Invoke `mbed compile` specifying the name of your platform and your favorite toolchain (`GCC_ARM`, `ARM`, `IAR`). For example, for the ARM Compiler 5: ``` mbed compile -m K64F -t ARM ``` Your PC may take a few minutes to compile your code. At the end you should get the following result: ``` [snip] +----------------------------+-------+-------+------+ | Module | .text | .data | .bss | +----------------------------+-------+-------+------+ | Misc | 13939 | 24 | 1372 | | core/hal | 16993 | 96 | 296 | | core/rtos | 7384 | 92 | 4204 | | features/FEATURE_IPV4 | 80 | 0 | 176 | | frameworks/greentea-client | 1830 | 60 | 44 | | frameworks/utest | 2392 | 512 | 292 | | Subtotals | 42618 | 784 | 6384 | +----------------------------+-------+-------+------+ Allocated Heap: unknown Allocated Stack: unknown Total Static RAM memory (data + bss): 7168 bytes Total RAM memory (data + bss + heap + stack): 7168 bytes Total Flash memory (text + data + misc): 43402 bytes Image: .\.build\K64F\ARM\mbed-os-example-blinky.bin ``` ### Program your board 1. Connect your mbed device to the computer over USB. 1. Copy the binary file to the mbed device . 1. Press the reset button to start the program. You should see the LED of your platform turning on and off. Congratulations if you managed to complete this test! ## Export the project to Keil MDK and debug your application From the command line, run the following command: ``` mbed export -m K64F -i uvision ``` You should see the following output: ``` Successful exports: * K64F::uvision .\projectfiles\uvision_K64F\Unnamed_Project ``` To debug the application: 1. Start uVision. 1. Import the uVision project generated earlier. 1. Compile your application and generate an `.axf` file. 1. Make sure uVision is configured to debug over CMSIS-DAP (From the Project menu > Options for Target '...' > Debug tab > Use CMSIS-DAP Debugger). 1. Set breakpoints and start a debug session. ![Image of uVision](img/uvision.png) ## Troubleshooting 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9` ``` mbed --version ``` If not, you can update it easily: ``` pip install mbed-cli --upgrade ``` 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.
