I am at ITS World Congress in downtown Detroit today, so I can't do any
testing until this evening...

Good, then later runs of the cubieboard2 have gotten a proper SID, that is good.

you are reporting.
Which version of Fedora are you running on your Cubietruck ?
Your F19 and last the
9/5 build of F21-minimal. Here is what I do for
xzcat /home/rgm/arm/Fedora-19-a10-armhfp-r3.img.xz > /dev/sdb; sync
I never saw anything after the R3 release.
With the respin images the kernel takes care of getting the MAC from the SID,
with the official F-21 images, u-boot needs to do this, and the u-boot included
is (not yet) new enough.
hmmm. For cubieboard2, I use your git repo:
git clone https://github.com/jwrdegoede/u-boot-sunxi.git
git checkout -B next origin/next
make -j4 CROSS_COMPILE=arm-linux-gnu- Cubieboard2_defconfig
make -j4 CROSS_COMPILE=arm-linux-gnu-
dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8
Is there a way to also make a uboot for the cubietruck to update what is

anything with the nand image, but went right to the SDcard image. I just don't get
how to do the nand poking to get something working from it.
The SID is in the SoC, it has nothing to do with the nand.
Well that is a start.

You can dump the sid by hooking up a serial console, and then pressing a
key to interrupt u-boot, then do:
md 1c23800 4
If I don't have an SDcard in the unit I end up at a sunxi# prompt. Is
this the same thing?
To get the SID contents, see here for example SID-s :
If this is non-0 on your cubietruck, then you should get a consistent MAC
with the respin images, and you should be able to get a consistent MAC
with F-21 by building (and installing) u-boot from here:
Makes no sense to me. What do I do with this?
Those are the official u-boot sources, and those now have everything needed
to run F-21. Note do not use this u-boot with the respin images, that does
not work (yet).
I did try yesterday. And it did not work. ;)
> anyway to set the SID if it is zero?
Not that we know of.
I will test the CT tonight.
