F&S i.MX7ULP Linux Release Y2020.03 (Yocto 2.4 Rocko)
This is a major release for fsimx7ulp. fsimx7ulp is the software for all boards from F&S that are based on the i.MX 7ULP CPU from NXP. Currently these are the modules PicoCoreMX7ULP. 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 two files:
fsimx7ulp-Y2020.03.tar.bz2
This is the main release itself containing all sources, the binary images, the documentation, examples and the toolchain.
sdcard-fsimx7ulp-Y2020.03.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
This will create a directory fsimx7ulp-Y2020.03 that contains all the files of the release.
Please read the file
doc/FSiMX7ULP_FirstSteps_eng.pdf.
It describes the first steps when working with the board and gives references to further reading.
Release Notes for fsimx7ulp-Y2020.03
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 "Y2020.03" of this release indicates a Yocto based release from March 2020.
2. Support for board PicoCoreMX7ULP revision 1.20
This is the first regular release that supports PicoCore7ULP. 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 4.9.88
The Linux kernel is now based on 4.9.88. By default, we are using the zImage format of the kernel now, not the uImage format as before. Here are some of the new features since the previous kernel 4.1.15.
- 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 2.4 (Rocko)
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 fus-setup-release.sh script. See LinuxOnFSBoards_eng.pdf for a detailed description.
5. New WLAN module Azurewave CM276NF
In the past, the WLAN module Laird Sterling-LWB5 was mounted. In the current HW revision 1.20 the new module Azurewave CM276NF 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 FSiMX7ULP_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 FSiMX7ULP_FirstSteps_eng.pdf document now really only shows a basic introduction to the work with boards of the fsimx7ulp 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 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.
