F&S i.MX93 Yocto Release 2025.08 (fsimx93-Y2025.08)

This is a major release for all F&S boards and modules based on the i.MX93 SoC, based on the NXP lf-6.6.52-2.2.1 release.

Supported Boards

• PicoCoreMX93 rev 1.10
• efusMX93 rev 1.00
• OSM-SF-MX93 rev 1.10

Please see the new revision of following file

FSiMX93_FirstSteps_eng.pdf

for a description of how everything is installed and used. This doc sub-directory also contains other documentation, for example about the hardware of the boards and the starter kits.

Please note that Yocto releases use a 'Y' for the version number. The version counting is independent form other releases.

Content

The release consists of the following files and directories:

Highlights

Here are some highlights of this release.

1. New Linux Kernel 6.6.101

The F&S Kernel is now based on the linux-fslc kernel.

The fslc kernel has LTS updates for the NXP release versions, so security fixes can be applied more easily.

The Linux kernel is now based on 6.6.101

• EEVDF replaces the existing CFS code scheduler.
• ReiserFS Officially Declared "Obsolete"
• KSMBD Declared Stable
• CephFS Completes Multi-Year Effort Adding FSCRYPT Support.
• EXT4 Lands A Nice Performance Improvement
• Tmpfs Gains New Features
• NFS Enables NFSv4.2 READ_PLUS Option By Default
• Brings Fixes, Partially Recovers From Scrub Performance Regression
• Adding Randomized Kmalloc Caches (Linux Security)
• Various Security improvements (Linux Security)
• Various kernel graphics improvements

  ... Many other improvements.

  (https://www.phoronix.com/review/linux-66-features)

  Of course, there are also many changes for other CPU types (like x86) and other graphics cores (like AMD, Nvidia, Intel) but these are not of interest here.

2. New bootloader U-Boot 2024.04

The U-Boot is now based on 2024.04. Add support for A/B Update, Secure Boot and OP-TEE to the U-Boot.

3. New Yocto version 5.0.11 Scarthgap

Updating poky to Version 5.0.11 Scarthgap. Updating other layers to their latest commits.

The meta-fus layer in now split into meta-fus-bsp and meta-fus-sdk. The meta-fus-bsp layer adds basic board support, while meta-fus-sdk adds additional features, which are note necessary to run the board.

The meta-fus layer is now based on meta-freescale and not meta-imx. meta-freescale offers better long time support and more stable releases, while meta-imx supports the newest features but is not as stable and suitable for production. The meta-imx layers are still downloaded for reference, but not included into the build. If you need features from them, please consider adding the changes to your own meta-layer.

4. New Docker based building system

The F&S releases now support Docker containers as default building machines. By using the Docker environment, the build process can be executed on any Linux host, as long as the Docker is installed. Starting FS_Development_Machine-Fedora-40_V0.2 Docker will be pre-installed and the development machines will not support support building the releases directly anymore.

If you do not want to use Docker, please check the Dockerfile for the dependencies. https://github.com/FSEmbedded/docker-fus/

1. Download manifest repository

   git clone -b fsimx93-Y2025.08 https://github.com/FSEmbedded/releases-fus.git

2. Prepare Yocto-Build environment Run setup-yocto to prepare your Yocto-Build environment. The script will read the repo manifest.xml file and syncs all repositories that are needed for Yocto.

   cd releases-fus/ ./setup-yocto

3. Prepare Docker-Environment The ./setup-yocto script is capable of setting up a Docker environment in which the bitbake program can be executed for the Yocto system. This command will open a docker shell, where you can execute all yocto commands as usual.

   ./setup-yocto --docker

5. New Version naming for F&S Linux, U-Boot and meta-fus

Linux and U-Boot and meta-fus now get their own version number to be more transparent and flexible. The Version numbers reflect the Version of the original package, if needed the NXP version and the F&S Version. For example the linux version name is composed like this

[Version Orig. Kernel]-[Version IMX]-[Version FS]

linux-v6.6.101-2.2.1-fus1.0

This way it is easier to recognize the applied patch levels and the same package versions can be used in multiple releases.

The actual packages versions are marked as annotated tags in the git history. The Name of the overall release (like fsimx93-Y2025.08) is still set as a light tag.

Hello,

this is normally not an issue. You have a requirement which needs configuration of the uart port. The drivers offers the device tree settings to configure this. Please see driver documentation for uart node. In general you may have better response if dma is disabled too.

no-dma

Hope this helps.

Hello Alfred,

sdcard image has all device trees on the first partition. Normally you can use our default device trees. Over the time our experience shows that our customer use different combination of boot divice. E.g. it is possible to configure our bootloader to use device tree from NAND or USB and other images like linux kernel and rootfs from eMMC. Also we desided to add some more binaries to our sdcard tar ball. But they are same default images like in our bsp binaries folder.

If you want to use several device trees for armstonea9 you can e.g compile the binary manuelly and add (copy) it inside the sdcard image. This can be done by mounting the image as loopback device. You will find more information online. (e.g. on wikipedia) It should be a easiest and fastest way from my point of view.

For production it can be more better way to add the divice tree to the machine file fsimx6.conf in .../meta-fus/conf/machine directory and add the your device tree to the kernel. For this it need to:

• Extend the KERNEL_DEVICETREE enviroment with your device tree
• Add the patch to recipe ../meta-fus/recipse-kernel/linux/linux-fus.bb
• (Re)compile the kernel e.g. commado bitbake -c compile linux-fus -f
• Build your image again. E.g. bitbake fus-image-std
• Boot the board and go to the bootloader command line interface
• Change the environment bootfd to bootloader name, which should be used. E.g. cmd 'editenv bootfdt' allows to change the env. value.
• Optional use 'saveenv' command to write the new value to the persistent memory.

Hope this helps.

i.MX8M-Plus Linux Release Y2023.03 (Yocto)

This is a maintenance release for fsimx8mp. fsimx8mp is the software currently for all boards from F&S that are based on the i.MX8M-Plus Quad CPU from NXP (or i.MX8M-Plus for short). Currently this consists of the boards armStoneMX8MP, PicoCoreMX8MP, PicoCoreMX8MPr2 and efusMX8MP. More 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 two files:

fsimx8mp-Y2023.03.tar.bz2

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

sdcard-fsimx8mp-Y2023.03.tar.bz2

If you copy the contents of this archive to an SD card, you can install our precompiled standard system in a very straightforward and comfortable way on the board. The SD card archive is meant for people who just want to try a release first without having to download the quite large main archive. Its content is also contained in the main release archive, so if you want to download the main archive anyway, you don't need to bother with the SD card archive.

These tar archives are compressed with bzip2. So to see the files, you first have to unpack the archives

Code

1. tar xvf fsimx8mp-Y2023.03.tar.bz2

This will create a directory fsimx8mp-Y2003.03 that contains all the files of the release.

Please read the file doc/FSiMX8MP_FirstSteps_eng.pdf. It describes the first steps when working with the board and gives references to further reading.

=========================================================================

Known Issues

The Link LED of the PicoCoreMX8MPr2 revision 1.00 is inverted. It will be on, if no link is detected and off if a link is detected.

The Activity will be indicated through blinking as expected. Unfortunately, this can not be fixed by software.

Release Notes for fsimx8mp-Y2023.03

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 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 "B2019.08" of this release indicates a

Buildroot based release from August 2019.

2. New U-Boot 2020.04

We have a considerably newer U-Boot now. One of the main new features is display support, so basically U-Boot can now be used to show a splash screen.

U-Boot will also show more information about the CPU type now, for example temperature range, possible speed, etc. The command "clocks" will show much more information about internal clock rates. And USB storage devices are detected faster than before.

U-Boot has experienced quite a lot of internal restructuring. For example it now also supports configuration via a Kconfig menu, similar to Linux kernel and Buildroot. After configuration with

make fsimx8mp_defconfig

simply call

make menuconfig

to show the menu. There you can select and de-select entries or move to sub-menus.

Moving all configuration options from the previous header file to this menu is a long-term and still on-going process. So not all features are available in the menu, yet.

U-Boot is now compiled and running in THUMB mode. This saves space that is needed for all the display code.

3. New Linux kernel 5.4.70

The Linux kernel is now based on 5.4.70. By default, we are using the Image format of the kernel now.

• Improvements and optimizations in memory management, for example better heap and page management (tmpfs, shmem), better protection against attacks by implementing stack, heap and memory randomization.
• Performance optimizations for the network stack, like faster TCP connections, quick killing of hanging network links, more features for the packet filter (firewall), smaller latencies on WLAN.
• Optimizations in block layer, for example better Device Mapper for LVM, improved parallel access to directories, more efficient access to SSDs, parallel access for NFS, kernel support for file copy, server-side copy for CIFS, NFS, XFS, support for hard discs with host-managed SMR (Shingled Magnetic Recording).
• Optimizations on file systems (NTRFS, EXT4, F2FS, NFS, XFS, Overlayfs, Ceph), new cluster filesystem Orangefs
• Many improvements in graphics stack, like DRM (Direct Rendering Manager), new open source graphics driver etnaviv for Vivante graphics on i.MX CPUs (etnaviv = vivante backwards)
• Better load balancing of processes to CPU cores, new cgroups v2, improved power and frequency handling, new cpufreq governor schedutil.
• New GPIO infrastructure not using sysfs, supposed to be faster.
• Support for USB SuperSpeedPlus (USB 3.1).
• Many many new and improved drivers for WLAN chips, touch controllers, audio codecs, cameras, MMC/SD cards, etc.

Of course there are also many changes for other CPU types (like x86) and other graphics cores (like AMD, Nvidia, Intel) but these are not of interest here.

4. Yocto 3.0 (Zeus)

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. [Source: https://www.freedesktop.org/wiki/Software/systemd/]

It is configured via the systemclt 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 fus-setup-release.sh script. See LinuxOnFSBoards_eng.pdf for a detailed description.

5. 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 FSiMX8MP_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 FSiMX8MP_FirstSteps_eng.pdf document now really only shows a basic introduction to the work with boards of the fsimx8mp 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 NBoot, U-Boot, Linux and Yocto 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.

-----------------------------------------------------------------------------------

The following list shows the most noticable changes in this release in more detail since our last regular i.MX8M-Plus 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.
