Building Chromium OS for Raspberry Pi (ARMv6)

I had previously written the instructions to build an older version of Chromium (via Berkelium) for ARM using Beagleboard/Overo rootfs in order to use it with Xibo digital signage. Recently I’ve been contacted by hexxeh, who maintains Chromium OS vanilla builds for x86 and MacOS computer, as he intends to provide Chromium OS for the Raspberry Pi, and you should be able to get a SD card image once everything is working from the site above. Today, I’ll post the steps followed to build Chromium OS LKGR (“the latest revision to pass only unit tests”) optimized for  ARMv6 processor with soft-float support, which is the type of processor (Broadcom BCM2835) used in the Raspberry Pi. Please note that although it can build, it still does not run properly and a few more changes are needed. First, you’ll need a fast machine to build Chromium OS in a reasonable amount of […]

Ubuntu on AllWinner A10 based Mele A1000 Set-top Box

I’ve recently received and reviewed the 70 USD Mele A1000 STB powered by AllWinner A10, but haven’t been able to hack it yet since I’ve have not received the USB to Serial cable necessary for debugging the board. However, somebody else (Tom Cubie) had time to hack the box and run Ubuntu from a SD card (while still keeping Android in the flash) as you can see below. This port does not seem to include hardware accelerated GUI just yet, but this is definitely a step in the right direction. Tom said he just followed the instructions at http://rhombus-tech.net/allwinner_a10/hacking_the_mele_a1000/ and http://rhombus-tech.net/a10_mmc_boot/ to have Ubuntu working, but those do not appear to be that clear at the moment.

Second Release of Debian 6 for Raspberry Pi

As Raspberry Pi boards have started to ship this week, the Raspberry Pi foundation has also posted a new Debian 6.0 “squeeze” release to the downloads section of raspberrypi.org this week-end. This release contains several performance enhancements, including enabling the 128K system L2 cache for the first time, and first-cut ALSA drivers. Enabling the L2 cache will boost the ARM CPU performance, however, it may decrease the GPU performance. So this setup is ideal for headless server, but for other applications, for example a media player decoding 1080p30 videos, the performance might actually go down. This is still customizable, as the L2 cache can be enabled / disabled with enable_l2cache parameter in the config.txt file stored on the SD card. The ALSA drivers are here for audio support, so audio output might not have been supported in the first release (TBC), except if they used another type of audio drivers […]
