Dr. Google is our friend.

I put

linaro user list

into the search and see:

I could never figure the C2-dualboard out.  Always thought it was a special project for some big Hadoop customer (or other server farm) that they decided to commercialize.

Nothing really supports it.  No uboot for it from sunxi, unless you somehow boot both?  Never really looked into it; never considered investing the money in one.

Yes, this forum board is basically dead as is the Cubieboard mailing list.  I still heavily use Cubies (2 and truck) with Fedora and Centos and now working with Nethserver to see it gets ported to Centos-armhfp.  But I am one of the last repliers here.  The Russian forum sometimes shows some activity.

There are still problems with the Cubieboard5 and uboot from sunxi.  Seems to be getting close.  Maybe by Fedora 30 it will work.  But then I have been considering a BananaPi based on the Allwinner R50 and find out that sata support for that chip won't happen until the 4.20 kernel (F29 is shipping with 4.18).  So I can't even jump ships to get a working quad board!  Also the Cubieboard5 is not native sata, but they emulate it off of USB and that is one of the problems.

I have no problem using generic uSD cards I get at the counter of my local Micro Computer Center.  But I use the Fedora installer, or direct dd of the provided Centos or Nethserver image onto a uSD card and take it from there.

Hope you get what you have working well enough for you.

Oh, one final note, if you will.  The wonderful Mali GPU is not supported in the sunxi uboot.  This means GTK3 goes into hw emulation mode and you get terrible graphics (read desktop gui) performance.  I have been told GTK2 is dead.  So Mali GPU is dead until someone contributes the needed code to the sunxi work.  Thus great for servers, but not for desktops.
I suggest you ask this one on the Linaro list, as it looks specific to a package availability, having nothing to do with Cubies.

As a Fedora/Centos user, I do most of my activity on their arm lists.
I put

Into google and got quite a bit of information including a pointer back here:

Try google yourself...

Go to and look up the various boards, and their uboot support state.  This will tell you which processor, graphic engine and the like for each product supported by sunxi uboot.

I have an old, rather cheap AOC monitor with VGA/DMI.  I use a DMI/HDMI connector and it works fine with my Cubieboard2 and Cubietruck HDMI.  Note that the Cubietruck VGA only kind of works.  This is a known limitation of its uboot.

I use Fedora and Centos as my distros.  I am a tester of both.

General Discussion / Replacement power cables

What would I specify on ebay to get some more power cables.

This USB to 4mm cable is really handy.  I have been using them for other things and now I need a few more...

A couple of updates.

First the uboots rpm is  uboot-images-armv7

And since my server is a Cubieboard2 with this rpm installed, it was easy to make a symlink to the directory or all the uboot files and update the page to the uboot location:

So this should simplify matters.  Note that the uboot for the Cubietruck Plus is NOT the one you want.  I will update this once they get things simplified for the Plus.
I have finally updated my Centos 7 howto:

It is really easy now to get Centos7 up and running.  You have an image choice of server, Gnome, or KDE (EPEL issues with Xfce still).

Caveat is you need a system where you can install uboot-tools to get the right uboot file.  For me it is easy on my Fedora notebook.  If your desktop does not provide uboot-tools, you can always first install Fedora28-arm:

Grab the uboot file and go to the Centos installation.

Or perhaps I can put the latest uboots on my server...  Hmmm.

Cubieboard 5 support in the works.  A few have it working.

I suspect Fedora works well with the latest kernel.

Fedora 28 (probably still 4.17.n) can be gotten from the production page:

You can get Fedora 29 or Fedora Rawhide (30) which already has 4.18 from:

I am currently testing F29-Xfce and minimal on Cubie2 as it has openSSL 1.1.1 beta.

There has been a thread on this over at the Centos7-arm SIG.

Go to:

And look at the "Cubieboard5 performance" thread I started.

I don't own a Cb5, but was looking into one.  Decided no due to that sata is via internal usb, but it started an effort to finally get the right uboot and kernel in place.

You may be able to use this kernel work for linaro.  Or switch to Centos7...
Try it with another OS would be my shotgun approach.

My expertise is with Fedora/Centos, and there is good support for Cubie on their arm lists.

I suspect you will need to ask this question on a lubuntu discussion list.  Most likely, find the right source and do a build on your lubuntu installation.

Never worked with the NAND.  If SHOULD be fast, but limited.

SSD is always fastest. HDD comes a close second.

Thing is not only reads but also writes for all the logging unless you have an OS that you turn off all logging.

Read the posts on SATA booting to see how to boot directly from SATA.
