Cubieboard 1 (1G RAM Version)

• script.bin: Compiled FEX file [1].
• u-boot.bin: U-Boot bootloader binary (can be found after 32KiB (at least) on the SD card)
• sunxi-spl.bin (short for 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

Description of the Boot process.

Creating loopback devices for images with partitions: losetup –show -f -P test.img

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 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:

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

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