====== Cubieboard 1 (1G RAM Version) ======
===== Some names/files =====
  * ''script.bin'': Compiled [[http://linux-sunxi.org/Fex_Guide|FEX]] file [[http://linux-sunxi.org/Script.bin|[1]]].
  * ''u-boot.bin'': U-Boot bootloader binary (can be found after 32KiB (at least) on the SD card)
  * ''sunxi-spl.bin'' (short for [[http://en.wikipedia.org/wiki/SPL|Secondary Program Loader]], no cubieboard/allwinner specific name): Boot0, which will be loaded by BROM and loads in turn U-Boot (can be found after 8KiB (at least) on the SD card)
  * BROM: The very first immutable stage of the boot process. Tries to load Boot0 and falls back to FEL boot.
  * ''boot.src'': Kernel parameters compiled from ''boot.cmd''

===== Installing Arch Linux on SD Card =====
[[http://archlinuxarm.org/platforms/armv7/allwinner/cubieboard|Official installation instructions]]

The official instructions cover only the 512M RAM version. Therefore the OS can actually only see 512M of RAM on a 1G board.

To get the full 1G, you have to ...
  * use ''sunxi-spl.bin'' and ''u-boot.bin'' from the [[http://dl.linux-sunxi.org/users/amery/sunxi-3.0/latest/cubieboard_hwpack.tar.xz|hwpack]] ([[http://linux-sunxi.org/Hwpack|info]])
  * change ''fexfile=cubieboard_512.bin'' to ''fexfile=cubieboard.bin'' in the ''uEnv.txt'' (''cubieboard.bin'' is already on the SD card)
  * Replace ''ethaddr'' with ''mac_addr'' and change the MAC address in ''uEnv.txt''

Section "Creating a uEnv.txt" can be ignored since you already copied a uEnv.txt. Never the less you have to modify it as described above.

At the end, ''uEnv.txt'' should look similar to this:
<code>
boot_mmc=fatload mmc 0 0x43000000 ${fexfile}; fatload mmc 0 0x48000000 ${kernel}; bootm 0x48000000
extraargs=mac_addr=00:CE:39:xx:xx:xx console=tty0
fexfile=cubieboard.bin
</code>


Start HDMI output: ''modprobe lcd && modprobe hdmi && modprobe fbcon''
