Ubuntu 12.04 on ODroid-X Development Board

Yesterday, Hardkernel released the first version of Ubuntu for ODroid-X development board based on Linux 3.6-rc1 and Linaro Ubuntu Desktop 12.07. This is still early work, but here’s the current status: Linux Kernel 3.6-rc1 with gcc 4.7.1 Linaro toolchain SMP driven Quad-Core processing PMIC device driver USB 2.0 High-speed Host driver for Exynos-4412 HSIC interface Ethernet + USB Hub device driver LCD display driver HDMI display driver (Very early version and it may have HDMI 1.4a compatibility issues with some monitors) To do: Audio codec driver eMMC device driver Clock control driver 3D HW-GPU X11 driver (This may need couple of months) Power-off support WiFi module is not working with Ubuntu GUI. Hardkernel Wi-Fi module is not working due to missing driver There are 2 images: one for LCD display kits, one for HDMI output that can be downloaded via: BitTorrent – One file with both images?

Rikomagic To Sell an AllWinner A10 Android & Ubuntu Netbook

Rikomagic, the company that sells the MK802 mini PC, is planning to sell a netbook based on AllWinner A10 processor that runs both Android and Ubuntu operating systems. This device looks very much like the H6 netbook  with a 10″ 1024×600 display, 1 GB RAM, 4 to 8 GB flash. an SD card slot, 3 USD ports, audio in/out and a front camera. Android currently runs in the internal flash, and Ubuntu can be booted from an SD card. In the video below, Andy Kirby of Rikomagic gives an overview of the netbook and shows a demo of Ubuntu Desktop running from an SD card. The Linux OS seems to run relatively smoothly as he shows pages rendered in Chromium.However, hardware acceleration (both OpenGL and VE) is missing, and Youtube video playback is very slow as it is rendering in software. Open Office is also a bit slow, but it’s […]

HardKernel ODroid-X Review with Android 4.0.4

Following my ODroid-X unboxing and first boot post, I planned to review ODroid-X board with both Android and Ubuntu. However, I found out that an Ubuntu image will only be released later this week, so I’ll focus on Android review for today, and try Ubuntu once it becomes available. The default firmware come with a few standards applications, and an ODROID app that: Provide links to developer resources Features a file explorer Has a WiFi section that show WiFi information such as signal strength and let you test the network performance Has a GPS section (useless for this board) Has a Sensor section, but there are none in ODROID-X. Has a camera section that let you show the camera input. It works with the module provided Has a others section with 3D compass test (not used for ODROID-X) The Dev Tools application is also installed. But there was not really […]

15 Linaro OnAir Sessions about Android, Linux, Debugging and Software QA

Linaro has planned 15 virtual conferences between Monday, August 13 and Saturday, August 18, 2012. Those online events will deal with the work done at Linaro, including software optimization, software QA, Android and Linux kernel development, Open Embedded on ARMv8 and more. Those conferences are public and anybody can join. All times indicated below are GMT+07:00 (Bangkok), so you can either mentally convert the time (recommended), or click on the links below to get the date and time in your timezone. Exploring The Performance Impact of PGO and LTO on ARM– Mon, August 13, 5:00 PM Abstract: Profile guided and linked time optimisation (PGO and LTO) are two of GCC’s cross program optimisations that should improve both the startup and runtime of typical programs.  We know that they basically work on ARM but don’t know the potential speed up or the work involved in proper support. This session will cover […]
