    Hi all,
    Anyone using Arch Linux with real time kernel on the UDOO Quad?
    Can't find any info on that...
    Using packer (like pacman but also gets packages from AUR repository) I get this:

    [pedro@alarm ~]$ packer -S linux-rt
    Aur Targets (1): linux-rt
    Proceed with installation? [Y/n]
    warning: armv7h missing from arch array
    Edit linux-rt PKGBUILD with $EDITOR? [Y/n] n
    ==> ERROR: linux-rt is not available for the 'armv7h' architecture.
    The build failed.

    So there is no linux-rt available on AUR for armv7h... to easy to be true...
    So please, what i sthe best way to proceed?
    Thanks in advance,
    Pedro

    Thank you Andrea for your reply!

    Can you please send me some info on which source code version of Arch Linux was used to create the SD image that is available on Arch Linux web site?
    And what changes were made to that original configuration in order to make it run on the UDOO Quad? Is there a forum or wiki on these matters?

    Many thanks in advance for any info on how to advance faster on this! My objective is to connect the UDOO Quad to a B&R PLC using openPOWERLINK. Just the openPOWERLINK compile / config is taking me a lot of time, if I can get some help on the Arch Linux real time configuration that would be awesome!

    Greetings
    Pedro

    As @ektor5 told me, we are not tied or connected anyhow to ArchLinux ARM and they don't use our sources.
    On the basis of our modifications, ArchLinux has changed the uboot and the kernel

    Ok thanks Andrea. I'll investigate on the Arch Linux side...

    I'm using the image on the platforms page:
    $ uname -a
    Linux alarm 4.4.1-2-ARCH #1 SMP Sun Feb 7 16:22:57 MST 2016 armv7l GNU/Linux

    I dont know which package you use and what changes arch linux developer have introduced into the kernel. Vanilla 4.4 kernel shouldn't boot with udoo quad/dual.
