i.MX8MM Linux Release B2021.06 (Buildroot)

  • i.MX8M-Mini Linux Release B2021.06 (Buildroot)


    This is a major release for all F&S boards and modules based on the i.MX8M-Mini CPU (Solo, Dual and Quad), i.e. PicoCoreMX8MM. 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:


    fsimx8mm-B2021.06.tar.bz2

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


    sdcard-fsimx8mm-B2021.06.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 fsimx8mm-B2021.06.tar.bz2

    This will create a directory fsimx8mm-B2021.06 that contains all the files of the release.


    Please read the file doc/FSiMX8MM_FirstSteps_eng.pdf. It describes the first steps when working with the board and gives references to further reading.


    !!!! Important !!!


    Please note that this release is only compatible with PicoCoreMX8MM of Board Revision 1.30. The Board Revision can be found at the top Site of the board, printed in golden letters. (PCoreMX8MM Rev 1.30 TOP) Please contact F&S if you are owning a PicocoreMX8MM revision 1.20 or lower and want to use this release.


    This does not apply for PCBs for DDR3L based PicocoreMX8Mx (Rev. 1.20 PCoreMX8Mx) Here, the release can be used from revision 1.20 upwards.


    !!!! Important !!!


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


    Here are some highlights of this release.


    1. New Boot concept for i.MX8MM based boards (fsimx8mm-Nboot)


    The fsimx8mm-NBoot is a first stage bootloader preinstalled to the boards, similar to the fsimx6 Nboot.It handles many board-specific configurations like the DRAM initialization or assembly variants so the user does not need to care about it.


    It does not yet offer the full functionality of the fsimx6 NBoot, like an own command line, but will be further developed in this direction.


    NBoot and U-Boot can be easily updated using the new fsimage command, that automatically flashes to the right hardware partitions.

    For more information on the fsimage command please see the Linux On F&S Baords documentation chapter "Command fsimage To Handle F&S Images"


    2. New Linux kernel 5.4.70


    The Linux kernel is now based on version 5.4.70.


    From https://kernelnewbies.org/Linux_5.4:

    This release includes the kernel lockdown mode, intended to strengthen the boundary between UID 0 and the kernel; virtio-fs, a high-performance virtio driver which allows a virtualized guest to mount a directory that has been exported on the host; fs-verity, for detecting file tampering, like dm-verity but works on files rather than block devices; dm-clone, which allows live cloning of dm targets; two new madvise() flags for improved app memory management on Android, support for new Intel/AMD GPUs, support for the exfat file system and removing theexperimental status of the EROFS file system; a new haltpoll cpuidle driver and governor that greatly improves performance for virtualized guests wanting to do guest-side polling on the idle loop; and blk-iocost, a I/O cgroup controller that attempts to calculate the cost of I/O more accurately. As always, there are many other new drivers and improvements.


    3. New eMMC-Image format sysimage


    We introduce a new image format for eMMC based boards, that contains a raw Uboot partition, a FAT32 Boot partition for Kernel and device trees, and an ext4 partition for the rootfs. This image can be flashed to the eMMC as a whole, allowing an easy update of the system at once. For further information please the Linux On F&S Baords documentation chapter Mass Storage Devices -> eMMC.


    Please note that the sysimage layout of Buildroot and Yocto currently differ so exchanging separate partitions between those two might not work.

    This will be fixed in future releases.


    4. Update to Buildroot 2021.02.2


    Buildroot 2021.02 has many many updated packages, for example Qt-5.12.2, busybox-1.33, wayland 1.18, weston-imx 9.0 and imx-gstreamer-1.16.2.

    We actually use buildroot-2021.02.2, which is a newer version that already has some more fixes.


    5. New toolchain fs-toolchain-9.3-armv8ahf


    It showed that some packages needed newer Kernelheaders to compile. So we have updated the toolchain again. Please use this new toolchain together with the code of this release.


    Remark: When changing the toolchain, you should always clear the compiler cache, e.g.


    rm -r ~/.ccache ~/.ccache-buildroot


    Otherwise the compiler may mix up precompiled code from the cache with newly compiled code, causing strange runtime errors.



    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. Them 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

    NBoot, U-Boot, Linux and Buildroot/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.

    Your F&S Support Team

  • Hello,


    yes we are also planning a new release for i.MX6 boards. Probably it will be also based on Linux 5.4.70 / Buildroot 2021.02 / Toolchain 9.3. We don´t have an exact timetable but I guess it will be released during the year.

  • Touchscreen Fix for 3.5" MIPI-DSI Display mit PCAP Touch ( B.LCD.22)


    The Touchscreen of the 3.5" MIPI-DSI Display mit PCAP Touch ( B.LCD.22) is not working with the following combination:


    Boards: PcoreMX8MM-V1-LIN, PcoreMX8MM-V13-LIN [Rev1.3]

    Adapter: ADP-MIPI2MIPI1 [Rev 1.2]

    Display: 3.5" MIPI-DSI Display mit PCAP Touch ( B.LCD.22)

    Releases: Y2021.04, B2021.06


    To fix this, you can either apply the attached patch to the Linux Kernel and rebuild the device tree or make the following U-boot settings:


    Run the following command in the U-boot console:

    Code
    1. setenv fix_EE0350_touch 'fdt addr $fdtaddr; fdt set i2c1/mxt336u interrupt-parent <0x00000036>; fdt set i2c1/mxt336u interrupts <0x00000000 0x00000002>;'

    Edit the $fdt variable and add the command run fix_EE0350_touch befor the booti command. For example

    Code
    1. editenv fdt
    2. mmc rescan; load mmc 2 0x43000000 picocoremx8mm-lcdif-adp-mipi2mipi1-ee0350et-2cp.dtb;run fix_EE0350_touch;booti 40480000 - 0x43000000
    3. saveenv

    ( The $fdt variable may look different, depending on where the device tree is loaded from)


    Boot, the board. The touchscreen should work now.


    Your F&S Support Team

  • Add error handling for the install script with eMMC


    Currently the UBoot update process does not react to errors in UBoot commands issued in the install and update scripts. So whenever the load command fails, the RAM area will get written to the destination as it is. For boards with a NAND flash this is not as problematic, because the UBoot will not be affected by the update. For eMMC however the UBoot is included in the sysimg file. An error in the load command results in a corrupt UBoot and the board will not be bootable without external flashing software.


    The updated install script checks for errors that might occur in the load command and aborts the update process before actually writing the corrupt data. Also the chunksize for the eMMC update process is reduced to support more USB sticks.


    The attached zip file contains the install script as a text file and precompiled binaries. The folder structure is exactly as in the release directory with binaries/, sdcard/ and sources/, so it is enough to unpack the zip file inside the release directory fsimx8mm-B2021.06/.



    Your F&S Support Team

  • Hello,


    please use fsimx8mm_wayland_defconfig for i.MX8MM.

    We decided to not use the term "std" anymore to make it more transparent that there is no X11 support for i.MX8 boards anymore.


    All config giles can be found in the configs/ directory in the buildroot main directory.


    Your F&S Support Team

  • Post by alfred ().

    This post was deleted by the author themselves: error ().
  • Nice, I found the file!! Thank you!


    No X11 support for iMX8 ? Only wayland ?

    I need X11 because our client intends to use Teamviewer and this doesn't support Wayland.


    Can I try X11 on buildroot and test?

  • F&S i.MX8M-Mini Buildroot Release B2021.06.1 (fsimx8mm-B2021.06.1)


    Please see the file


    doc/FSiMX8MM_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 minor release for all F&S boards and modules based on the i.MX8M-Mini CPU (Solo, Dual and Quad), i.e. PicoCoreMX8MM. 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 Buildroot releases use a 'B' for the version number. The version counting is independent form other releases.


    fsimx8mm-B2021.06.1.tar.bz2

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


    sdcard-fsimx8mm-B2021.06.1.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 fsimx8mm-B2021.06.1.tar.bz2

    This will create a directory fsimx8mm-B2021.06.1 that contains all the files of the release.


    Please read the file doc/FSiMX8MM_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 PicoCoreMX8MMr2 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.


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

    Here are some highlights of this release.


    1. Support for PicoCoreMX8MMr2


    Add support for the new PicoCoreMX8MMr2 board version, that features

    the rtl8211f ethernet phy.


    2. Rework Device Tree structure


    Derive the device trees for the picocoremx8mm and picocoremx8mmr2 from a

    common picocoremx8mm.dtsi, so changes can be easily applied to both of them.


    3. Improve the rtl8211f phy support


    Improve the realtek phy by making the following features configurable:

    - Disable CLKOUT

    - ALDPS mode

    - Spread-Spectrum Clocking for RXC, SYSCLK and CLKOUT

    - Setting one LED for each: link indication and activity

    - Disable GBit


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


    The following list shows the most noticeable changes in this release in

    more detail since our last pre i.MX8M-Mini 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

    change log.
