New Buildroot Release fsimx6-B2020.04

  • i.MX6 Linux Release B2020.04 (Buildroot)


    This is a maintenance release for fsimx6. fsimx6 is the software for all boards from F&S that are based on the i.MX6 Solo, DualLite, Dual or Quad CPU from NXP (or i.MX6 for short). Currently this consists of the boards efusA9, armStoneA9, armStoneA9r2, PicoMODA9, NetDCUA9, QBlissA9 and QBlissA9r2. 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:


    fsimx6-B2020.04.tar.bz2

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


    sdcard-fsimx6-B2020.04.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 fsimx6-B2020.04.tar.bz2

    This will create a directory fsimx6-B2020.04 that contains all the files of the release.


    Please read the file doc/FSiMX6_FirstSteps_eng.pdf. It describes the first steps when working with the board and gives references to further reading.



    Release Notes for fsimx6-B2020.04


    Here are some highlights of this release.


    1. New framebuffer names and display backlight handling


    The framebuffer devices are now internally named after the function, i.e. "lcd", "hdmi", "ldb0", "ldb1". And the display backlights also switch on and off together with the display driver. This was different in the past.


    Please note that this adds some additional on-off cycles when starting the X-Server. This is because the X-Server reconfigures the display several times and each time the display is switched off temporarily.


    You can add property unblank_delay to an mxcfb node to hide any unwanted display content before the display shows the regular image.

    Code
    1. mxcfb0: fb@0 {
    2. compatible = "fsl,mxc_sdc_fb";
    3. late_init = <0>;
    4. unblank_delay = <50>; /* 50ms delay */
    5. ...
    6. };

    We also fixed a bug in this release, where a backlight brightness of 0 was not handled correctly if the PWM brightness uses inverted logic. It is fixed by adding the new property "keep-power" to the underlying PWM port in the device tree. We have added this to all PWM nodes now.



    2. Video playback also possible without camera


    Previously, hardware accelerated video playback with gstreamer was only possible when also a camera was configured in the device tree. We fixed this. Now playback is always possible, also without a camera setting.



    3. Update to Buildroot 2019.05.3


    We have updated to the newer release Buildroot 2019.05.3 that has some more security and bug fixes.



    4. New toolchain fs-toolchain-8.3-armv7ahf


    It showed that Qt5-webengine will not compile with a toolchain before gcc-8.0. 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.

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

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



    5. Add support for A/D-Converter ADS1118


    Thanks to a customer, we now have support for the A/D-Converter ADS1118.



    6. Default LVDS display replaced


    The ChiMei LVDS display that F&S used to ship with some Starter Kits is not available anymore. We will ship a different display from now on. Therefore we also changed the default settings for LVDS in the Linux device trees so that upcoming customers will have a working display.


    If you still need the previous settings, simply remove the two comment slashes at the beginning of the following line in the device tree and re-build the device tree. Then the old settings will be active again.

    Code
    1. //#define DISPLAY_LVDS_CHIMEI

    This change was actually already part of the previous release but we missed to mention it in the README text back then. We added a comment in the forum, but we repeat it here, just to be sure.



    7. Improved LinuxOnFSBoards.pdf documentation


    We have further added content to the generic Linux documentation. Now everything up to and including chapter 6 with the F&S specific U-Boot enhancements is rather complete. But the chapters behind that are still work in progress and need more attention in the future.


    -----------------------------------------------------------------------------------


    The following list shows the most noticable changes in this release in more detail since our last regular i.MX6 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.

    Your F&S Support Team

  • Hello,


    For the BSP fsimx6-B2020.04.1 there are three patches:

    • 0001-Add-ssc-support-for-rtl8211f
    • 0002-Set-MDIO-lines-low-while-not-being-used
    • 0003-Increase-polling-time-for-link-status-to-5-sec

    We have noticed that the patch 0002 needed by efusa9r2 breaks the compatiblity with the older efusa9 board because here the mdio lines are not used in device tree but used in kernel driver.

    We would like to support the efusa9 and the efusa9r2 at the same time.


    Now the new version fsimx6-B2020.04.2 is released:


    In this release only the patch 0001 semms to be integraded. Are the other two patches no longer necessary ?

    So the BSP B2020.04.2 should be compatible with the version efusa9 and the version efusa9r2 without any patch or ?


    Thank you

    Kristoffer


  • Hello,


    There is a fault in the patch where the functions would still be called even if no entries in the Device-Tree were set. In the attachements you can find the corrected patch, where compatiblity for the efusA9 is restored.

    These two patches are only needed for the revision 1.10 of the efusA9r2 as there is a hardware fault which needs to be mitigated. Because the revision 1.20 is already out, the patches are not included in the release fsimx6-B2020.04.2 and must be applied for the revision 1.10.


    Generally the release fsimx6-B2020.04.2 is compatible with the efusA9 and efusA9r2 with and without the patch.
