uLipe | 0:a59680ccdb41 | 2 | |
uLipe | 0:a59680ccdb41 | 3 | This is a very simple guide, reviewing the steps required to get Blinky working on an mbed OS platform. |
uLipe | 0:a59680ccdb41 | 4 | |
uLipe | 0:a59680ccdb41 | 5 | Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli). |
uLipe | 0:a59680ccdb41 | 6 | |
uLipe | 0:a59680ccdb41 | 7 | ## Get the example application! |
uLipe | 0:a59680ccdb41 | 8 | |
uLipe | 0:a59680ccdb41 | 9 | From the command line, import the example: |
uLipe | 0:a59680ccdb41 | 10 | |
uLipe | 0:a59680ccdb41 | 11 | ``` |
uLipe | 0:a59680ccdb41 | 12 | mbed import mbed-os-example-blinky |
uLipe | 0:a59680ccdb41 | 13 | cd mbed-os-example-blinky |
uLipe | 0:a59680ccdb41 | 14 | ``` |
uLipe | 0:a59680ccdb41 | 15 | |
uLipe | 0:a59680ccdb41 | 16 | ### Now compile |
uLipe | 0:a59680ccdb41 | 17 | |
uLipe | 0:a59680ccdb41 | 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: |
uLipe | 0:a59680ccdb41 | 19 | |
uLipe | 0:a59680ccdb41 | 20 | ``` |
uLipe | 0:a59680ccdb41 | 21 | mbed compile -m K64F -t ARM |
uLipe | 0:a59680ccdb41 | 22 | ``` |
uLipe | 0:a59680ccdb41 | 23 | |
uLipe | 0:a59680ccdb41 | 24 | Your PC may take a few minutes to compile your code. At the end you should get the following result: |
uLipe | 0:a59680ccdb41 | 25 | |
uLipe | 0:a59680ccdb41 | 26 | ``` |

uLipe | 0:a59680ccdb41 | 47 | ### Program your board |
uLipe | 0:a59680ccdb41 | 48 | |
uLipe | 0:a59680ccdb41 | 49 | 1. Connect your mbed device to the computer over USB. |
uLipe | 0:a59680ccdb41 | 50 | 1. Copy the binary file to the mbed device . |
uLipe | 0:a59680ccdb41 | 51 | 1. Press the reset button to start the program. |
uLipe | 0:a59680ccdb41 | 52 | |
uLipe | 0:a59680ccdb41 | 53 | You should see the LED of your platform turning on and off. |
uLipe | 0:a59680ccdb41 | 54 | |
uLipe | 0:a59680ccdb41 | 55 | Congratulations if you managed to complete this test! |
uLipe | 0:a59680ccdb41 | 56 | |
uLipe | 0:a59680ccdb41 | 57 | ## Export the project to Keil MDK and debug your application |
uLipe | 0:a59680ccdb41 | 58 | |
uLipe | 0:a59680ccdb41 | 59 | From the command line, run the following command: |
uLipe | 0:a59680ccdb41 | 60 | |
uLipe | 0:a59680ccdb41 | 61 | ``` |
uLipe | 0:a59680ccdb41 | 62 | mbed export -m K64F -i uvision |
uLipe | 0:a59680ccdb41 | 63 | ``` |
uLipe | 0:a59680ccdb41 | 64 | |
uLipe | 0:a59680ccdb41 | 65 | To debug the application: |
uLipe | 0:a59680ccdb41 | 66 | |
uLipe | 0:a59680ccdb41 | 67 | 1. Start uVision. |
uLipe | 0:a59680ccdb41 | 68 | 1. Import the uVision project generated earlier. |
uLipe | 0:a59680ccdb41 | 69 | 1. Compile your application and generate an `.axf` file. |
uLipe | 0:a59680ccdb41 | 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). |
uLipe | 0:a59680ccdb41 | 71 | 1. Set breakpoints and start a debug session. |

uLipe | 0:a59680ccdb41 | 75 | ## Troubleshooting |
uLipe | 0:a59680ccdb41 | 76 | |
uLipe | 0:a59680ccdb41 | 77 | 1. Make sure `mbed-cli` is working correctly and its version is greater than `0.8.9` |
uLipe | 0:a59680ccdb41 | 78 | |
uLipe | 0:a59680ccdb41 | 79 | ``` |
uLipe | 0:a59680ccdb41 | 80 | mbed --version |
uLipe | 0:a59680ccdb41 | 81 | ``` |
uLipe | 0:a59680ccdb41 | 82 | |
uLipe | 0:a59680ccdb41 | 83 | If not, you can update it easily: |
uLipe | 0:a59680ccdb41 | 84 | |
uLipe | 0:a59680ccdb41 | 85 | ``` |
uLipe | 0:a59680ccdb41 | 86 | pip install mbed-cli --upgrade |
uLipe | 0:a59680ccdb41 | 87 | ``` |
uLipe | 0:a59680ccdb41 | 88 | |
uLipe | 0:a59680ccdb41 | 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. |
