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?

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, 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.
