New FreeRTOS Release fsimx6sx-V2019.12

  • F&S i.MX6SX FreeRTOS Release (20.12.2019)

    Please see the file


    for a description of how everything is installed and used.

    This is a major FreeRTOS release for fsimx6sx. fsimx6sx is the software for all boards from F&S that are based on the i.MX6-SoloX CPU from NXP. Currently these are the modules efusA9X, PicoCOMA9X and PicoCoreMX6SX. Further boards may be added to this family in the future. All these boards can work with software that is created from this release package.

    This release brings new versions to all parts of the software stack. Here are some highlights of this release.

    1. New version numbering

    We have changed the way how we name versions. In the past we had a version number made up of a major part m and a minor part n. Then we used Vm.n for FreeRTOS-BSP releases. Release versions were counted individually for each CPU architecture. But then a "new" CPU type unfortunately had a smaller version number than an "old" CPU, even if the code was coming from the same sources or was even newer. This caused some irritations and misunderstandings of what release is actually the newest.

    So from now on we will use the year and month of the release instead. For example the "2019.12" of this release indicates a FreeRTOS-BSP based release from December 2019.

    2. Add support for rpmsg-lite

    Now NXP´s rpmsg-lite is used instead of openAMP RPMsg. This makes the size of the images significant smaller.

    3. Rework of the directory layout

    Change directory layout but the examples can be built with the same commands as before.

    4. Merge fsimx6sx and fsimx7ulp git repositories

    The two git repositories fsimx6sx and fsimx7ulp are merged together so it´s easier to handle.

    5. Add hello_world_split example

    The hello_world_split example shows the user how to split an example in different memory regions like DDR, OCRAM and TCM.


    The following list shows the most noticable changes in this release in more detail since our last regular i.MX6SX FreeRTOS-BSP release. Please note that the source code is also used for other platforms. This is why you will also find references to other CPU types and F&S boards here in the changelog.
