New release fsvybrid-V2.2

    Vybrid Linux Release V2.2


    We have uploaded a new Linux version for all boards and modules based on the Vybrid CPU to our server, i.e. the fsvybrid architecture: armStoneA5, PicoCOMA5 and NetDCUA5. This release is running on all platforms of this architecture at the same time. So you can download the same binaries for NBoot, U-Boot, Linux kernel and Buildroot root filesystem to any of the Vybrid boards and it will run.


    The release consists of two files:


    fsvybrid-V2.2.tar.bz2
    This is the main release itself containing all sources, the binary images, the documentation, examples and the toolchain.


    sdcard-fsvybrid-V2.2.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 fsvybrid-V2.2.tar.bz2


    This will create a directory fsvybrid-V2.2 that contains all the files of the release.


    Please read the file doc/Vybrid_FirstSteps_eng.pdf. It lists the meaning of all files and shows how to install and use everything.


    Release Notes for fsvybrid-V2.2


    This is a maintenance release for fsvybrid. However as the last release was more then two years ago, a rather impressive list of modifications has accumulated. fsvybrid is the software for all boards from F&S that are based on the Vybrid CPU from Freescale/NXP. Currently this consists of the boards armStoneA5, PicoCOMA5, NetDCUA5 and some customer specific boards. All these boards can work with software that is created from this release package.


    Here are some highlights of this release.


    1. U-Boot 2014.07


    U-Boot has received quite a lot of changes that increase stability and functionality. For example when downloading a file with tftp or nfs, the size of the already downloaded part is now output at the end of each row of progress hash marks. If a cable is unplugged, the board switches faster to the other ethernet port, but at the same time slow connections are not timed out too quickly. This was a problem now and then in previous versions.


    Also support for USB sticks is added, i.e. you can use USB sticks for installation and updates now.


    Please note that the variables for boot strategies now start with a dot instead of an underscore. This means that these variables are usually hidden in the printenv command. Issue


    Code
    1. printenv -a


    to see these hidden variables, too.


    2. Many bug fixes and improvements in the kernel


    The SGTL5000 sound driver has experienced quite a lot of enhancements to increase the volume and reduce clicking noises when starting and stopping playback.


    Overlays are now actually working, you can stack up to four windows on top of the desktop, including alpha blending.


    Support for PWM is now available (also for LEDs), SPI and ADC drivers are fixed and do work much better now, RS485 is added to the serial driver and the clock infrastructure is heavily improved, for example by supporting spread spectrum now (improves EMC compatibility).


    3. Buildroot 2016.05


    We switched to a considerably newer buildroot version. This includes a lot of updated and also new packages.


    4. New toolchain


    We also have a new toolchain that is based on GCC-5.2. This now fully supports the ISO-C11 standard and partly the C++14 standard.


    5. New examples


    We have added a new set of examples to the release. These examples consist of small programs that show how to use a specific device or feature like a GPIO pin, SPI device or PWM port.



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


    The following list shows the most noticable changes in this release in
    more detail since our last Vybrid release fsvybrid-V2.1. Please note
    that the source code is partly 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. Some of these changes have already been part of
    other releases for other boards.
