New Yocto Pre Release fsimx8mm-Y2020.06

  • F&S i.MX8MM Linux Release Y2020.06 (Yocto 2.5 Sumo)

    This is a pre release for fsimx8mm. fsimx8mm is the software for all boards from F&S that are based on the i.MX 8M Mini CPU from NXP. Currently these are the modules PicoCoreMX8MM. 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.

    The release consists of file:


    This is the pre release itself containing all sources, the binary images, the documentation, examples and the toolchain.

    The BSP tar archive is compressed with bzip2. So to see the files, you first have to unpack the archives Code

    1. tar xvf fsimx8mm-Y2020.06.tar.bz2

    This will create a directory fsimx8mm-Y2020.06 that contains all the files of the release.

    Please read the file


    It describes the first steps when working with the board and gives references to further reading.

    Release Notes for fsimx8mm-Y2020.06

    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 Buildroot releases and Ym.n for Yocto 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, preceeded by a 'B' for Buildroot releases and a 'Y' for Yocto releases. For example the "Y2020.05" of this release indicates a Yocto based release from May 2020.

    2. Support for board PicoCoreMX8MM revision 1.10

    This is the first regular pre release that supports PicoCore8MM. The PicoCore is only 40mm x 35mm but is a very powerful System-on-Module with many I/Os. This release supports the current HW revision.

    3. New Linux kernel 4.14.98

    The Linux kernel is now based on 4.14.98. By default, we are using the uImage format of the kernel now, not the zImage format as before. The kernel is based on NXP 4.14.98_2.3.1 release.

    4. Yocto 2.5 (Sumo)

    With this release systemd will be the default init system for the example- fus-images.

    Systemd is a init system and service manager for Linux operating systems. It provides a system and service manager that runs as PID 1 and starts the rest of the system. systemd provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. It is configured via the systemctl application.

    Also the root file system will now be mounted as read-write by default. This can be changed to read-only when setting up the build enviroment via the script. See LinuxOnFSBoards_eng.pdf for a detailed description.

    5. WLAN module Marvell SD8997

    In the current HW revision 1.10 the module Marvell SD8997 is mounted.

    6. Documentation

    In the past, the documentation that was included in the release package itself was often superseded by newer versions on our website.

    But people continued to use the outdated version of the release, causing unnecessary complications.

    To avoid this, from now on only the software related documentation is directly included in the release and we have added a chapter to FSiMX8MM_FirstSteps_eng.pdf that contains direct links to the appropriate resources on our website. There you can download the newest versions of hardware documentations, schematics, layout files, certificates, accessories, add-ons, adapters and similar things.

    The software documentation is completely reworked. The FSiMX8MM_FirstSteps_eng.pdf document now really only shows a basic introduction to the work with boards of the fsimx8mm architecture. And there is a new document LinuxOnFSBoards_eng.pdf that shows a more in-depth view of a Linux system in general and of the F&S versions of U-Boot, Linux and Buildroot in particular. This is still work in progress, some chapters are not fully done yet and will be revised in the future. Check our website from time to time to see if there is a newer version of this document.
