F&S i.MX93 Yocto Pre-Release 2024.09 (fsimx93-Y2024.09-pre)

A new pre-release for fsimx93 is available.

It is based on the following components:

- Yocto 5.0 (Scarthgap)

- Linux 6.6.x

- U-Boot 2024.04

Currently supported boards:

- PicoCoreMX93, OSM93

!!ATTENTION!!

Please note that this is a pre-release, which is only meant for testing and not suitable for production!

There may be huge changes to the software and the distribution method in the future.

Please report any bugs in this thread.

!!ATTENTION!!

Building the Pre-Release

4. Improved Image versioning

5. New Release concept over github

We now provide our Linux gits over github at https://github.com/FSEmbedded. All release and pre-release states will be pushed here. For now, we will not push each single commit to github.

Also the release sources are not added to the release tar anymore, but will be downloaded from github during the setup process.

The versions of the different gits of a release can be looked up in the fs-release-manifest.xml file in the release tar directory.

6. New Azurewave wlan driver

Additional to the mainline SD-BT-8997 driver we now provide the NXP version. This driver supports additional security features, optimized. STA and AP modes and improved roaming.

To activate the nxp mlan driver uncomment the respective lines in: recipes-kernel/kernel-modules/files/mxm-wifiex.conf Also comment out the line for the mainline mwifiex driver.

Please note that bluetooth is currently not supported with the nxp-mlan driver. For Bluetooth please use the mainline driver.

The following list shows the most noticeable changes in this release in more detail since our last release for this platform. 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 change log.

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.

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.

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

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

!!! Important !!!

Please note that the update from older nboot, uboot version to the newer is necessary

for both bootloader nboot and u-boot in the same update procedure.

Do not update only one bootloader!

!!! Important !!!

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.

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.

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

Please note that the update from older nboot, uboot version to the newer is necessary

for both bootloader nboot and u-boot in the same update procedure.

Do not update only one bootloader!

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.

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.

i.MX8M-Plus Linux Release Y2022.12 (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 and PicoCoreMX8MP. 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-Y2022.12.tar.bz2

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

sdcard-fsimx8mp-Y2022.12.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-Y2022.12.tar.bz2

This will create a directory fsimx8mp-Y2022.12 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-Y2022.12

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,
