  • armStoneMX8M-Plus Linux Maintenance Release Y2024.07.1 (Yocto 4.0)

    F&S armStoneMX8MP Yocto Release 2024.07.1 (armstonemx8mp-Y2024.07.1)


    Please see the file


    doc/FSiMX8MP_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 armStoneMX8MP.


    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
    • as git hashes
    • 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. Add support for armStoneMX8MP revision 1.10


    It feature an optional RS485 transceiver, an EEPROM, a new audio codec and several smaller bug fixes and improvements.


    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.

  • USBA not initalized in UBOOT

    Hello,


    we have tested this board with this release and it seems to work.

    Some questions:

    • So only the upper connector is failing? The lower one works?
    • Is the error Baseboard or SOM specific? Does the failing SOM work with an different Baseboard?
    • Did you try different USB sticks?
    • Did you test the Uboot from the new release fsimx8mp-Y2024.07?

  • imx-sdma: All bds consumed,restart now.

    Hello,


    the reason, why this message is not displayed with mainline kernel 6.11 should be, that the warning does not exist in the imx-sdma driver code there:


    linux mainline 6.11-rc4:

    https://github.com/torvalds/li…ivers/dma/imx-sdma.c#L873


    linux-imx 5.15.y

    https://github.com/nxp-imx/lin…ivers/dma/imx-sdma.c#L988


    It was introduced in kernel 5.10, however, it also disappeared in newer imx-kernel versions:


    linux-imx 6.1.y

    https://github.com/nxp-imx/lin…vers/dma/imx-sdma.c#L1024


    I cannot find any commit, that removed this warning so it seems that it just was not merged into the newer kernel versions.

    This is the commit, which introduced the warning:

    [1] https://github.com/nxp-imx/lin…ce86c47c8cb10c3567a37bad0


    We did not see these kind of messages yet, however we did not do any intense sdma testing so far of the imx6sx.

    The commit message indicates, that is has something to do with high CPU loads. As the imx6sx is a Solo CPU, this might in fact be a problem.

    The fact, that the warnings where added in kernel 5.10 explain, why you did not see them so far.


    Is your CPU load very high, when these warnings occur?


    Could you try to apply the changes from [1] to the mainline kernel and see if they still not occur?

  • LED driver on armstoneA9r3

    Hello,

    this comes from the pca9632 GPIO-Expander on the ADP-AStone2EDT2-LCD Display adapter.

    https://github.com/FSEmbedded/…s/armstonea9qdl.dtsi#L897


    If you are not using this, you should be ok to set

    status = "disabled";


    However, you will also have to disable the nodes that reference it

    https://github.com/FSEmbedded/…s/armstonea9qdl.dtsi#L226

    https://github.com/FSEmbedded/…s/armstonea9qdl.dtsi#L517


    It should also be OK to ignore it, but it would be cleaner to just disable these unused nodes.

  • reboot forces poweroff and vice versa

    Hello,


    good to hear that it works with your baseboard.


    There might be an supply issue on our baseboard that may cause a sporadic trigger on the boot select line when doing a soft reset under certain conditions.


    We will investigate that further.

  • New Buildroot Release fsimx6-B2024.04

    Hello,


    like already mentioned, i did get the same sdma errors with the fsimx6_min_defconfig as you described and was able to fix it by adding the IMX specific buildroot packages.


    And you mentioned, that you do not get these errors with the wayland_defconig.


    I also wonder, why you don't get the sdma logs in your boot messages

    Code
    1. imx-sdma 20ec000.sdma: firmware found.
    2. imx-sdma 20ec000.sdma: loaded firmware 3.6


    So my guess is that there are some missing packages in your rootfs or kernel.

    Could you send us your kernel and buildroot defconfig via mail?


    Your F&S Support Team

  • New Buildroot Release fsimx6-B2024.04

    Hello,


    I was able to reproduce your issue by adding the following lines to the fsimx6_min_defconfig

    Code
    1. BR2_PACKAGE_ALSA_UTILS=y
    2. BR2_PACKAGE_ALSA_UTILS_AMIXER=y
    3. BR2_PACKAGE_ALSA_UTILS_APLAY=y
    4. BR2_PACKAGE_ALSA_UTILS_SPEAKER_TEST=y

    and runnign speaker-test


    By additionally adding these lines to fsimx6_min_defconfig the error did not accrue anymore and speaker-test worked as intended


    Code
    1. BR2_PACKAGE_FREESCALE_IMX=y
    2. BR2_PACKAGE_FREESCALE_IMX_PLATFORM_IMX6Q=y
    3. BR2_PACKAGE_FIRMWARE_IMX=y

    The imx-sdma driver was build as a module.

    Could you try to add these lines to your buildroot defconfig as well?


    Your F&S Support Team

  • reboot forces poweroff and vice versa

    Hello,


    could you provide some additional information on the reboot issue?

    Is this happening regularly or just some times?

    If you connect the board to your PC via UBS-Device, does the board get recognized by your PC after the issue occures?

    This would hint to a problem with the Bootselect pin.


    Your F&S Support Team

  • New Buildroot Release fsimx6-B2024.04

    Hello,


    we definitely successfully tested speaker-test with the fsimx6_wayland_defconfig.

    However, it might be true that the fsimx6_min_defconfig is not working, because of the missing sdma firmware.


    ALSA device list:No soundcards found. with imx-smda as module is expected, as the driver is getting loaded after the rootfs.


    Could you provide a full bootlog with this error?


    Your F&S Support Team

  • libgpio-tools

    Hello,

    please excuse the late answer.

    Could you post the exact gpiod command, you are using?


    Did you make sure, that the pins, you are trying to use, are routed to GPIO in device tree?

    You might have to to thisis additionally, because not all pins are routed to GPIO by default.


    For example for for muxing the SD_B DATA pads to GPIO with a 100k internal pullup you would have to add the following node to your DTS

    You can find the pin muxing macros at

    https://github.com/FSEmbedded/…/boot/dts/imx6q-pinfunc.h

    For information on the pad settings, please see

  • efusa7ul led gpio in uboot

    Hello,


    this is an English forum so I will answer in English.


    You wan to use a status led in U-Boot, but GPIO3_IO23 is not woring.

    Did you configure the correct pin mux and pad-settings for GPIO3_IO23 ?

    Currently, device tree is not used for F&S i.MX6 boards in U-Boot so you will have to set this in the board file

    board/F+S/fsimx6ul/fsimx6ul.c


    You can have a look here, how to do so

    https://github.com/FSEmbedded/…/fsimx6ul/fsimx6ul.c#L320

    https://github.com/FSEmbedded/…/fsimx6ul/fsimx6ul.c#L343


    You will have to set the following pin muxes for GPIO3_IO23

    https://github.com/FSEmbedded/…dts/imx6ul-pinfunc.h#L636


    You should also do this for GPIO3_IO22 , because this is currently ony muxed to gpio because of our default LCD settings

    https://github.com/FSEmbedded/…/fsimx6ul/fsimx6ul.c#L924


    I hope this helps.

  • fw_printenv does not work reliable

    Hello,


    the eMMC boot partitions are always mounted read only by default.

    We would recommend to keep it that way and only mount read/write if you have to write the environment.

    This is, because the bootloader is also saved to these partitions, and should be protected

    After that, you should mount it read only again.

  • QT5 Crosscompile MX8MP Yocto

    Hello,


    if you have added additional QT libraries, you should use also install a new QT image, so the libraries installed on the board match the one from the toolchain.


    If not you can just use the fus-image-qt6 example image.
