I have installed lubuntu to my Cubieboard2 and I have also connected a 2.5” SATA HDD. I wanted to know if my power supply is providing enough power so I tried to measure current output from 5V power supply.
I used cheap small USB power meter (find also some on eBay for less then 5€).
My results varies according to HDD usage:
I have installed Lubuntu on my new Cubieboard 2. I have also attached HDD to SATA so I have more space to store my media. This posts describes the steps needed to install and configure media server to share my media to other devices (media players). I spent some time to select the right one and chose minidlna tool (also known as ReadyMedia, lightweight DLNA/UPnP-AV server targeted at embedded systems).
According to Ubuntu documentation the MiniDNLA daemon serves media files (music, pictures, and video) to clients on a network. Example clients include applications such as totem and xbmc, and devices such as portable media players, smartphones, and televisions.
MiniDLNA is a simple, lightweight alternative to MediaTomb, but has fewer features. It does not have a web interface for administration and must be configured by editing a text file.
The main advantage of cubieboard is it’s SATA connector. I have old HDD from notebook, so I wanted to use it as a media server.
This post has 3 parts related to HDD connected to Cubieboard2 with lubuntu:
There are many ways to see all disks and partitions but my favorite command is lsblk:
sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL NAME FSTYPE SIZE MOUNTPOINT LABEL sda 149.1G nand 3.7G |-nanda vfat 64M Volumn `-nandb ext4 3.6G / mmcblk0 241M `-mmcblk0p1 vfat 241M SSD
or also fdisk:
I’ve bought BMP085 barometric pressure sensor and my goal was to get pressure and temperature data via I2C interface to my Cubieboard running linux (cubieboard2-lubuntu-installation).
I2C bus is used by many integrated circuits and is simple to implement. Any microcontroller can communicate with I2C devices even if it has no special I2C interface so I wanted to enable I2C also in my Cubieboard2 to get direct access to sensors.
I executed the following steps to install apache with PHP on my cubieboard2 with lubuntu.
Lets start with installation that will take about 25MB:
sudo apt-get install apache2 sudo apt-get install php5 sudo /etc/init.d/apache2 restart
When I installed Lubuntu on my new Cubieboard2, the print screen was not working. When I hit the “Print Screen” button I got this message:
I’ve fixed it by installing the scrot application:
sudo apt-get install scrot
If you hit “Print Screen” or “Alt+Print Screen” you will see a new file *_scrot.png in you home directory.
When I install new Lubuntu NAND image to my new Cubieboard2 I had only 2GB of space out of 4GB available.
I followed this forum to expand the filesystem to 4GB.
sudo nand-part
In my case I used this nand-part command:
sudo nand-part -f a20 /dev/nand 32768 'bootloader 131072' 'rootfs 7569408'
the number in bootloader is the same as previous partition size.
The number in rootfs is the sum of previous partition size of partition 2 and partition 3 that we wanted to merge.
I use VNC to access the graphical interface from my PC to a Cubieboard running Lubuntu. I chose TightVNC and spent some time configuring it. A helpful guide on ubuntuforums.org (currently offline — see status) got me started, but I needed to make changes, so I documented what actually worked.
I have just bought cubieboard and installed lubuntu and I want to have synchronized time with NTP server. NTP is a TCP/IP protocol for synchronising time over a network – Network Time Protocol.
