WORKING! - Re: uboot for the Cubieboard2 - not so easy

YES!  I have a working ethernet:

# ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN group default qlen 1000
    link/ether 02:c4:03:82:c1:53 brd ff:ff:ff:ff:ff:ff
    inet 208.83.67.183/28 brd 208.83.67.191 scope global dynamic eth0
       valid_lft 259182sec preferred_lft 259182sec
inet6 2607:f4b8:3:3:c4:3ff:fe82:c153/64 scope global noprefixroute dynamic
       valid_lft 33sec preferred_lft 23sec
    inet6 fe80::c4:3ff:fe82:c153/64 scope link
       valid_lft forever preferred_lft forever

I will assume other cubieboard2 items different from cubietruck will be right as well. But I think the only one I care about is the ethernet.

Now to install tigervnc-server and see if I can connect to it (I am using the f21-xfce build eventhough video is not working yet).

For me anyway. I am begining to see how the pieces are suppose to fit together.

The installer script is coded for only the Cubietruck, and if you don't capitalize it, the script fixes that.

There IS a dtb for the cubieboard2:

/run/media/rgm/__boot/dtb-3.16.0-0.rc7.git1.1.fc21.armv7hl/sun7i-a20-cubieboard2.dtb

But no .bin supplied.
Correct.

I got u-boot-sunxi-cubieboard2.tar.xz from someplace on Jul 24 which has in it:
That won't work because it is missing the "generic distro support" patches
Fedora's images rely on.

I've a u-boot tree which supports a lot more allwinner devices then just the
cubietruck, and does include the generic distro support.

To build this do the following (on an x86 machine)

yum install gcc-arm-linux-gnu
git clone https://github.com/jwrdegoede/u-boot-sunxi.git
cd u-boot-sunxi
git checkout -B next origin/next
# git checkout -B next origin/next
Branch next set up to track remote branch next from origin.
Switched to a new branch 'next'

make -j4 CROSS_COMPILE=arm-linux-gnu- Cubieboard2_defconfig
# make -j4 CROSS_COMPILE=arm-linux-gnu- Cubieboard2_defconfig
   HOSTCC  scripts/basic/fixdep
/bin/sh: gcc: command not found
make[1]: *** [scripts/basic/fixdep] Error 127
make: *** [scripts_basic] Error 2

Looks like there is something else I need to install...
It seems like you've never build anything from source on your system.

For starters you will need to install gcc:

yum install gcc

Given that your system is not setup to build software you may need
some other things too though.

Yep. I am rather inexperienced doing builds and such. I need real good cookbooks like you supplied here. Installed gcc, and nothing else was asked for. I first cloned the card I have built up, and then ran your dd of the uboot. Next to the cubieboard2 back together (monitor, keyboard, console, and the like) and watch the boot.
