F&S i.MX6SX Yocto Release 2024.12.1 (fsimx6sx-Y2024.12.1)
Please see the file
doc/FSiMX6SX_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.
This is a maintenance release for all F&S boards and modules based on the i.MX6-SoloX CPUs from NXP.
Currently these are the modules efusA9X, efusA9Xr2, PicoCOMA9X, PicoCoreMX6SX.
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.
Please note that Yocto releases use a 'Y' for the version number. The version counting is independent form other releases.
The release consists of the following files and directories:
- README.txt Release notes (this text)
- setup-yocto Script to download and install the Yocto release
- fs-release-manifest.xml Release Manifest, containing the used versions
- binaries/ Precompiled images (full names)
- sdcard/ Precompiled images (names as expected by install script)
- doc/ Hardware and software manuals, schematics
Here are some highlights of this release.
1. New Linux Kernel v5.15.185-2.2.0-fs1.0
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 mainline version 5.15.185 and NXP Version 2.2.0
2. New bootloader U-Boot u-boot-2021.04-v2021.04-fs1.2
Provide some minor bug fixes.
2. meta-fus layer is now based on poky 4.0.29
We have updated the poky layer to version 4.0.29 and many other layers to their latest versions. For a detailed description see fs-release-manifest.xml
3. 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-v5.15.185-2.2.0-fs1.0
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.
4. Support Silex WLAN Chip on the efusA9X(r2)
The new driver version is based on version 4.5.25.38 of the original Qualcomm driver which is available in branch CNSS.LEA.NRT_3.1 on repository (tag v4.5.25.38)
There is also a Silex-specific version available on request that improves roaming, adds bang radar and other improvements. Ask F&S if interested.
Known Issues
1. The Slilex Bluetooth Chip on the efusmxA9X(r2) is not supported.
There is currently no driver available for the Linux Kernel 5.15.
For Silex Bluetooth chip support, please use the release fsimx6sx-B2019.11.1 for basic Bluetooth evaluation.
