[fedora-arm] Fedora-Minimal-armhfp-21_Beta-TC4 -- not booting on Cubietruck

[Robert Moskowitz]

I downloaded:

https://dl.fedoraproject.org/pub/alt/stage/21_Beta_TC4/Images/armhfp/Fedora-Minimal-armhfp-21_Beta-TC4-sda.raw.xz

And the checksum (sha256sum) agrees.  I build the SD card with:

/home/rgm/arm/fedora-arm-image-installer/fedora-arm-image-installer.sh 
--image=/home/rgm/arm/Fedora-Minimal-armhfp-21_Beta-TC4-sda.raw.xz 
--target=Cubietruck --media=/dev/sdb --norootpass

I put the SD card in my Cubietruck and here is what I get on the serial 
console:

and there it sits.

I have a couple days for testing until I start travel, what should I try 
to trouble shoot this?

Also I see that there is now a /usr/share/uboot/cubieboard2/ directory, 
but it is not one of the script install options.  How do I build a 
cubieboard2 SD card for testing?

thanks
