The guide is come from https://github.com/jwrdegoede/sunxi-fedora-scripts .

1. Download the img file from Fedora-19-a10-armhfp-r3.img.xz
2. Insert an 8G SD card, note any data on the card will be destroyed! Note:some SD cards are not suite for the img ,maybe appear printed some wrong , so you have to change an other card .
3. Make sure the card is not mounted, run “mount” and if the card shows up in the output umount its partitions
4. Write the img file to the card, ie as root do:

     $xzcat Fedora-19-a10-armhfp-r3.img.xz > /dev/XXX
     $sync

5. Remove the card, and re-insert it. The uboot partition should get automatically mounted.
6. As root (or through sudo) run: <uboot-part-mount>/select-board.sh, for cubietruck ie:

     $sudo  /XXX/uboot/select-board.sh cubietruck   

7. umount the uboot and rootfs partitions, ie:

     $umount /XXX/uboot
     $umount /XXX/rootfs

8. Your sdcard is now ready for use.The first time boot the card shoud be use amount of time.
9. *Before* powering up your cubietruck device connect it to an hdmi or dvi monitor.
10. When first booting from the sdcard inserted Fedora will automatically reboot once, this is part of the process to resize the root partition to fill the entire sdcard and is normal behavior.
11. After the automatic reboot Fedora will start with the initial-setup wizard:
12. Configure networking, note:
    • If you've an A20 board, your ethernet may have a random mac-address,so if you want to configure a static ip-address and want it to stickacross reboots, go to the ethernet-tab, select the mac-address fieldand delete its contents, so that the static ip address you're configuring does not get tied to the random mac-address.
13. Setup the time zone.
14. Set a root password.
15. Create a user.
16. Log in as the just created user.
17. Enjoy Fedora on your cubietruck.

• Wifi doesn't work on r3 version

The Wifi driver haven't been merged to linux-sunxi kernel, so the module doesn't work currently on r3 version. But a working wifi driver can be found at github.com/cubieboard2/linux-sunxi branch sunxi-3.4-ct-v101.
