The newer cubieboard 2 (cb2) finally arrived about 3 weeks ago and started researching on how to use it. The problem is as you search for cb2 info you will come across tons of cb1 info. Also since this unit is fairly new you will see lots of conflicting info. After 3 full weeks of trying to figure out how to get debian on the flash drive I finally have it working. Below are the steps required to get yours working. Warning: This will erase android on your cubieboard. I’m assuming you are using debian/ubuntu based linux distro to install this.
1) download the 7z image http://cubian.org/downloads/
2) install the tools to extract it:
3) extract the image
4) After you extract the image it is now time to write the image to a mini sd card. The mini sd card needs to be at least 1GB to fit the image. You also want to make sure your sd card isn’t mounted. Also figure out which /dev/ device your sd card is assigned to using fdisk -l. In this example my sd is assigned to /dev/sdb
5) Now put the sd card into your cb2 device and connect the power. Once the device boots you should see a login prompt. The username/password is cubie/cubie. Now use ifconfig to get the ip address of the unit. I immediately ssh into the unit because my hdmi monitor does not support the current resolution it is using. So almost everything is off the screen. If you know how to fix this please let me know.
6) Now ssh int your cb2 which also uses a non standard port of 36000.
7) now run patch your cb2 so it is fully up to date.
8) Install all the cb2 tools.
9) Now you want to upgrade the kernel to the lastest version. As of writing this kernel 3.4.43 is the latest version. For some reason it kept saying failed to download…are you connected to the inernet? To fix this I had to change some CPU settings I found on a forum post.
10) Log back into the cubieboard2 to install the kernel
11) After the reboot connect back to the cb2. Now we are going to install the tool to boot the debian instance onto the nand flash.
12) Now there is one setting that isn’t going to work because the mount point for the filesystem wasn’t correct. So I had to fix this.
13) Now reboot the device and remove the sd card and the cb2 should boot from the nand flash.
14) Just incase run these commands to re enable CPU stuff:
15) There is another bug now where apt-get update won’t work on the nand due to the cubian mirror not having a key:
free space after install with Ruby and Rails installed:
