  • What is the login and password in linux .
lubuntu debian debian-zh cubian arch CbOS
login/password linaro/linarocubie/cubieboar and root/cubieboardchird/chird cubie/cubie root/rootroot/tll

Fedora-lxde :you should use the monitor (default output is HDMI)to set the password of root and set up the new user when first boot,reboot the system .

Password of root should be set by yourself in all distros.

About CubieBoard

  • Backup/Restore a SD card system image

If you're not going to specify a block size with dd, you can simply redirect from/to /dev/sdX:

gzip < /dev/sdX > bkp.img.gz
gunzip < bkp.img.gz > /dev/sdX
  • How to use whole SD card

you may use GPARTED to make it, but you may use other PC to help you, you can check for more information. Also you can try to use the resize2fs command, e.g.

#resize2fs /dev/mmcblk0p2

About CubieTruck

  • Where I can get a default kernel config and sys_config file?
  • Why Cubietruck pcb shape is different than Cubieboard?

Cubietruck is the second PCB model, it much different between Cubieboard&Cubieboard2. Cubietruck supports 2GB RAM, VGA jack, Wifi&BT on-board, all them need to expand the PCB size. Most important, we want it is fit a 2.5 inch HDD.

  • Why Cubietruck pcb has gap in rectangle shape?

  This gap was designed for HDD(Hard disk) adding
  • What is meaning of different color LEDs on cubietruck?
1 blue heartbeat running
2 orange cpu0 cpu0 load
3 white cpu1 cpu1 load
4 green mmc0 mmc0 load
  • How to put case on Cubietruck?
  • Wich battery voltage and type should be used?

Cubietruck supports power by Li-battery even with 2.5-inch HDD or SSD. The specification of the Li-battery is almost like the one which used in most of cell phones. If you have a free cell phone battery, you can use it to power Cubietruck by soldering two wires. This Li-battery has the following key parameters: Rating voltage=3.7V, Charge voltage=4.2V, Over current>=4A. The capacity of this Li-battery is not important I think, the more the better. But crucially, you should pay lots of attention in the positive and negative pole. You will damage Cubietruck if the Li-battery electrodes are connected in wrong way. You can find out the connection electrodes on the PCB of Cubietruck. Lithium battery is a kind of dangerous goods in transportation, so you need to DIY by yourselves.

  • Is there any Linux application where you can monitor battery level?

exported via sysfs

  • It´s possible to switch betwen DC Adapter to battery without booting it

Of course yes.

About Business


A20 Version A/B

A20 Rev.A

A20 Rev.B

  • For Version A, android v1.00 image may not work, and cause the board unable to boot or enter FEL mode. So if you were unlucky to meet with such problem, please upgrade to android v1.01 as soon as possible. Linux image is okay for both version A and B.
  • To upgrade to Android v1.01 on cubietruck(ver B chip)
Way A:
1. wait for RTC battery run out, maybe a couple of days
2. Flash v1.01 or later firmware with livesuit

Way B:
1. Make short-circuited RTC battery on board with wire after poweroff
2. Flash v1.01 or later firmware with livesuit

Way C:
1. Make a bootable sd card
#dd if=u-boot-sunxi-with-spl-ct-20140107.bin of=/dev/sdX bs=1024 seek=8

2. Insert sd card, power up
We don't need it bootup, just clean some register value on PMU
3. Remove sd card
4. Flash v1.01 or later firmware with livesuit
