Cubieboard v1 OS (A10 Based) / Re: Mainline kernel - u-boot from NAND

Further, look here:

The place to ask about this is on the sunxi list.

According to people that work with uboot and current kernels, it probably will won't work to put uboot on to NAND, but it might not take much more work on uboot.

If you are capable of making contributions to uboot (I am not), then join the sunxi uboot list and work with them on what needs to be added.  Otherwise wait until I get someone else to do the work.  This may take some real time (like months).

With both Fedora and Centos, using current uboot, I only have uboot on the uSD, and all partitions on the sata drive.  As long as there are no partitions on the uSD, uboot tries elsewhere for the partitions.

I have been meaning to ask on the Fedora-arm list about putting uboot on NAND, this is the incentive to do that...

Beginners / Re: Which Linux for Cubietruck (Cubieboard 3)?

btw,  no mali drivers either for the most part.

gtk2 is ok, but gtk3 is a dog.

Fedra28 hdmi was decent.  Fedora29 is painful.

Cubietech needs to lend a hand in opening mali.

what you are up against is the sunxi uboot work has not provided vga support.  none of the distros that use it can drive vga as a result.  and there is no plan to add it.

look for an hdmi-to-vga converter.

I have not been sucessful with these an Fedora/centos.

great to hear someone is getting direct Cubietech support.

Again, the Linaro user list.  This is Linaro specific.  There are many other A10 boards out there with similar installation challenges and you will get more help there.

But please share your experiences here to help other people searching for Cubieboard help.

Sorry I can't be of more help, but I am in the Fedora/Centos camps and you will find me a regular there in their arm user lists!

Beginners / Re: I have a CubieBoard2-dualcard and can't get it to boot
« on: October 14, 2018, 11:54:42 pm »
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.

Beginners / Re: Working with cheap China HDMI display

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...


General Discussion / Re: Centos 7 for Cubieboard 2 and 3 (Truck)
« on: August 24, 2018, 08:53:02 am »
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.

General Discussion / Centos 7 for Cubieboard 2 and 3 (Truck)

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.
