OK. back doing some testing. So far all with F19.

Read Hans de Goede's post on the F19 and the Allwinner (Cubie) back on
12/26/2013. He supposedly uses the SID for a consistant local scope
MACaddr. I Do get that on my Cubieboard2, but not on my Cubietruck.
Hans also told that there was a bunch of Cubie* with pre-production cpus
which lacked serial number.
AFAIK only cubieboard2 and olinuxino-a20-micro suffer from this, the
cubietruck is fine. On machines with an all 0 sid this indeed does not
work.
My SIX Cubieboard2 all are fine with a consistant MAC address.
Good, then later runs of the cubieboard2 have gotten a proper SID, that is good.
My one Cubietruck keeps coming up with the unique MACaddr. Exact opposite of what you are reporting.
Which version of Fedora are you running on your Cubietruck ?
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.
Perhaps there is a rev difference in the shipped nand? In all cases, I never did 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.
Is there any test I can run on my CT?
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
To get the SID contents, see here for example SID-s :
http://linux-sunxi.org/SID_Register_Guide
If this is non-0 on your cubietruck, then you should get a consistent MAC
with the respin images,
Well, I am not. For the Cubietruck. Here is the SID fromthe CT and
different MACaddr from a series of boots from the F19 image:
md 1c23800 4
01c23800: 165166c1 80485172 49514848 0881e2d7 .fQ.rQH.HHQI....
ea:99:af:e5:2f:5b
ea:22:02:c6:83:c8
fe:1d:9a:25:3b:48
Then I switch over to a Cubieboard2, also with F19:
md 1c23800 4
01c23800: 165166c4 80485072 56484848 0382c153 .fQ.rPH.HHHVS...
02:c4:03:82:c1:53
I notice with the C2, the MAC is the last word of the SID. But for the
CT, I cannot figure it out at all.
I have a bit of other testing to do (VLAN setup), then I will switch to
F21 and see if I can get the current uboot for the CT working.
and you should be able to get a consistent MAC
with F-21 by building (and installing) u-boot from here:
http://git.denx.de/?p=u-boot.git;a=summary
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).
anyway to set the SID if it is zero?
Not that we know of.
Regards,
Hans
