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 …
fexfile=cubieboard_512.bin
to fexfile=cubieboard.bin
in the uEnv.txt
(cubieboard.bin
is already on the SD card)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
