    This is really interesting and I think I’m going to try it out sometime. I’m even more excited about LIMA though.

    I don’t understand one think Android is always build as softfp (drivers same)
    and rest of os run as armv7hl (hard fp)
    it looks like libhybrids solve this part too right?

    there is some hack for NOKIA N9 (all hardfp libs) that is able to run softfp software for example angly birds star wars

    In this setup he’s using a standard Linux kernel and drivers with the Android libraries.
    I’ve checked, and confirmed, the rootfs is armhf, and the Android libs are armel, I’m not sure what kind of magic happens with libhybris.

    Doh. I was hoping that all that would be needed would be to copy a few files from and Android release for the target device over to Linux and et voila, the library do its work. Life’s never that simple though. 🙁

    I’ll try on my mele A1000 soon.

    Also video mode on TV was 12×7 at 50Hz, not sure yet why the framerate output was showing 25Hz

    Why even use libhybris on the cubieboard? We have proper armhf binaries for both X11 and fb for sunxi.

    I also have a Mele, I guess I just need to change script.bin and the bootloader, right?

    @Luc Verhaegen
    Just for experimentation.

    It’s still not working for me (I haven’t fixed my Cubie), as per the error message in this blog. I haven’t seen your error before. Have you tried to follow the advice from the log?:

    Try: zypper install -C “debuginfo(build-id)=4b82b0a4d8b1e617453c92539129e9ea245f4124”

    Aah sorry for late reply. I was expecting a email notification :).

    Yes I did try that. In fact with some further test I realise that error is same no matter I patch or not.

    I have also ensure that it’s patched properly but still situation same.

    I’ve tried (and failed) to remove the microSD card slot from my Cubieboard with a soldering iron and desoldering wire, but it seems quite challenging for me.

    You’d better check the original article, and ask Martin Brook directly. I’ve probably done a small mistake in this tutorial.

    “Installing and Running Mer

    Since we don’t build the image ourself, this step is rather easy, as we just need to download the image, and dump it to a micro SD card.

    wget nemo-cubieboard-tablet-cubieboard-mer-testing-armv7hl-weekly-20130413-1612-mmcblk0p.raw.bz2

    Proper URL please, thanks

    Hi, many thanks for the guide. I have a cubieboard, think I’ll have a look at Mer before anything else, and then move on to your guide!

    Thank you once again.

    I’ve managed to play the Qt5_CinematicExperience_rpi_1.0 example using qmlscene but something curious is happening:

    – I have no text being displayed, only graphical elements and images
    – near the top left corner of the screen I’m getting an intermittent cursor blinking
    – qmlscene crashes after a while and won’t allow me to re-run the example – only works after reboot

    I also tried the minimer example, with that I get the rotating/scaling wallpaper.

    Hi, there!

    Thanks for the guide. I struggled for a while with compiling the android image (I had to downgrade jdk, python and gnu make and still have some errors building it) and now decided to ask for help. If someone who manged to build the android image could provide the tar-archive of the /system folder (e. g. via ubuntu one, dropbox, …) you would save me hours of work. (And maybe others are interested in this, too?)

    Thanks in advance!

    Regards,
    maribu

    Hi, again!

    It looks like I got it working. Here is my /system folder of the output: http://ubuntuone.com/64JdjdWVq9F2E5p6gMQE1J I don’t have my Cubieboard at hands, so I haven’t tested it right now.

    Another interesting thing you can do with libhybris is using the android CedarX driver, which is said to work better than the native glibc version. Have a look here: http://linux-sunxi.org/CedarX/libve

    I also like to provide the extracted headers (using lutils/extranct-headers.sh from https://github.com/libhybris/libhybris) from the android Cubieboard source: http://ubuntuone.com/6PwRhU0CN1MZFrBUNJFnHL

    Regards,
    maribu
