Wandboard Releases Updated Android and Ubuntu Linux Images and Source Code

Since I’ve received my previous short review of the Wandboard Dual development board, there has been more work on done the platform with new Android and Ubuntu images, Jelly Bean source, Linux SDK release, and git repo setup. I’ve tried the binary images, and had a quick look at the source code and corresponding documentation. Android 4.1.2 Image and Source Code Wanboard has release an improved Android image on the 14th of March which you can download for both Solo and Dual version of the development board with the following Changelog: Fix HDMI audio/playback issue with certain monitor. Add support for wifi on wandboard-dual. Known issue: Might need to turn off “Avoid poor connections” in Wi-Fi ->Advanced to keep connection alive. I’ve given it a try in Wandboard Dual, and it seems Ethernet support is gone (Sorry my mistake, Ethernet IS working, but there’s no indication when it’s connected, and […]

Undistract-me Sends An Alert For Time-Consuming Commands in Linux

In Linux, some commands executed in the terminal such as make, wget, dd may take a while, so usually you’d just let them run in the background, and do some other work, drink tea, go for nap… while they are running, and come to check from time to time if the command has completed. Sometimes I even forget I run a particular command, and realize it has completed a few hours ago… It’s possible to add some command at the end of your command line, but it can be cumbersome, and you may forget to do it. The best would be automatic alerts for commands that take a long time, and undistract-me just takes care of that by sending an alert for commands that take more than 10 seconds (by default). In Ubuntu 12.04 and 12.10, you can install undistract-me as follows:

sudo add-apt-repository ppa:undistract-me-packagers/daily
sudo apt-get update
sudo apt-get install undistract-me

sudo add-apt-repository ppa:undistract-me-packagers/daily

sudo apt-get update

sudo apt-get install undistract-me

Undistract-me is part of Ubuntu 13.04 or […]

Linaro 13.03 Release with Linux Kernel 3.9 and Android 4.2.2

Linaro 13.03 is now available, and features Linux Kernel 3.9-rc3 and Android 4.2.2. This month, Linaro has released their first Origen Quad Android image, as well as Tiny Android build for Arndale. The ALIP image listed in the download page is still based on Ubuntu 12.11, but as doc Bormental noticed earlier this month, the latest ALIP Quantal 13.03 image is available for download at https://releases.linaro.org/latest/ubuntu/quantal-images/alip. Some development tools (gcc, g++, vi, make..) are now included in Android, so you can develop and build natively from your Android device. Linaro has kept on cleaning the Linux kernel ARM tree for Exynos and ST Ericson SoCs. More work has been done on big.LITTLE for both IKS and HMP, as well as ARMv8 OpenEmbedded, and an initial GRUB port on ARM UEFI is now available. Here are the highlights of this release: Automation and Validation A simple CLI tool for communicating with […]

Mini PCs (MK802+, UG802, GK802 & iStick A200) Linux Performance Comparison

Ian MORRISON (linuxium) has tested Linux with several mini PCs powered by different processors. The main point of his tests was to evaluate the performance difference between running Ubuntu 12.04 natively, or in a chroot in Android using tools such as Complete Linux Installer. I previously tried Linux on Android in ODROID-X, and found the applications start time when running from an low-end SD card pretty dismal, and the graphics performance poor. Ian had a different approach, and decided to use a subset of Phoronix Suite benchmarks to compare different hardware / software combination and posted the results in “mini PCs” G+ community. There’s a lot of data, and analyzing the results is not really straightforward without spending some time looking at the data. In this post, I’ll explain how the tests have been conducted, explain the results and try to draw a conclusion. Mini PCs and other Hardware Under […]

Ubuntu 11.10 Image for Hi802 / GK802 is Now Available for Download

About 2 weeks ago, Jasbir released an Ubuntu 11.10 image and installation instructions for GK802 and Hi802 mini PCs based on Freescale i.MX6. I could only find time to give it try yesterday and today. I’ll provide the steps I followed to install the image, and my quick first impressions of the stability and performance of this image. Installation Instructions I mainly followed the instructions provided by Jasbir, and run GParted to increased the partition size on my micro SD card. The image is for a 8 GB micro SD, but those instructions should work on 4GB SD card and greater, as the rootfs partition is only 3GB large. Download the Ubuntu 11.10 image, uboot, as well as the kernel image and modules in a Linux PC:

wget http://dl.miniand.com/jas-hacks/gk802/ubuntu_gk802.img.gz
wget http://dl.miniand.com/jas-hacks/gk802/u-boot.imx
wget http://dl.miniand.com/jas-hacks/gk802/uImage_3.0.35-0269_cpu_freq
wget http://dl.miniand.com/jas-hacks/gk802/modules_3.0.35-02695.tar

wget http://dl.miniand.com/jas-hacks/gk802/ubuntu_gk802.img.gz

wget http://dl.miniand.com/jas-hacks/gk802/u-boot.imx

wget http://dl.miniand.com/jas-hacks/gk802/uImage_3.0.35-0269_cpu_freq

wget http://dl.miniand.com/jas-hacks/gk802/modules_3.0.35-02695.tar

Copy the image, uboot and the kernel to the micro SD card by typing the commands below:

gzip -d ubuntu_gk802.img.gz
sudo dd if=ubuntu_gk802.img of=/dev/&lt;sd_device&gt;
sudo dd if=u-boot.imx bs=1k seek=1 of=/dev/&lt;sd_device&gt; &amp;&amp; sync
sudo dd if=uImage_3.0.35-0269_cpu_freq of=/dev/&lt;sd_drive&gt; bs=1048576 seek=1 &amp;&amp; sudo sync

gzip -d ubuntu_gk802.img.gz

sudo dd if=ubuntu_gk802.img of=/dev/<sd_device>

sudo dd if=u-boot.imx bs=1k seek=1 of=/dev/<sd_device> && sync

sudo dd if=uImage_3.0.35-0269_cpu_freq of=/dev/<sd_drive> bs=1048576 seek=1 && sudo sync

Replace /dev/<sd_device> by your […]
