Deprecation note!

Please note: this repository is deprecated and is no longer actively maintained.

However, this library is part of Arm's Mbed Cloud offering and as such the code is available via Mbed Cloud Client under mbed-client-pal folder. That repository is actively maintained.

PAL

This is the main repository for the Platform Abstraction Layer (PAL) project.

Releases

In order to get the latest stable and tested code, plesae goto releases and download the required release version - each release has a comment regarding which official mbedOS version was used for development and testing.

General Use Notes

• pal_init() API MUST be called before using any other PAL API, calling PAL APIs without initialization PAL can return with initialization error.
• pal_destroy() API MUST ba called to free any allocated resources by PAL Modules.

How To Build PAL Tests

MbedOS

1. Define the environment variable: MBEDOS_ROOT to be the father folder of "mbed-os".

2. cd $(PAL_FOLDER)/Test/

3. make mbedOS_all - This will build the tests for mbedOS5.2 (mbed-os-5.2)over Freescale-K64F board.

4. In order to build and run the tests over the platform please run:

    $ make mbedOS_check
   

5. In order to see debug prints please send the following flag DEBUG=1 in compilation command:

    $ make mbedOS_check DEBUG=1
   

6. In order to build single module tests please edit $(PAL_FOLDER)/Test/makefile under mbedOS5.1 platform, please change the value of the TARGET_CONFIGURATION_DEFINES to the desired module: (default value is for all exist modules)

    HAS_RTOS --> RTOS module APIs
    HAS_SOCKET --> Networking module APIs
