Linux 3.5 Release

Linus Torvalds has announced the release of Linux Kernel 3.5: Subject: Linux 3.5 released Ok, not a lot happened since -rc7. There’s a number of MIPS commits (for some reason MIPS has had a horrible track record with the -rc time schedule, I suspect I should just stop pulling late in the game), but most of the rest is pretty small. A couple of dm/md fixes, some gma500 work, make kgdb ‘dmesg’ command work again, some networking fixes, some xfs and cifs noise, yadda yadda. About 50% of the patch is actually the SPEAr clock name renaming that is just some search-and-replace. … Linux 3.4 brought updates to Btrfs file system, some new Intel, AMD and NVidia GPU drivers, X32 ABI, perf tool improvements and support for Yama security module and QNX6 file system. Linux 3.5 brings the following key changes: ext4 metadata checksums:  Ext4 has added the ability to […]

Gumstix TurtleCore Expansion Board for iRobot Create

Last month, Gumstix announced the TurtleCore expansion board for iRobot Create Programmable Robot, featuring 3 USB ports, several male-header pins with GPIO access, as well as standoffs and screws to support the TurtleCore in the Create cargo bay.. The TurtleCore is a baseboard for TI OMAP3 and Sitara based Overo COMs or Overo STORM series of COMs that replaces the Command Module on iRobot Create to provide a more flexible and powerful solution. Overo COMs have very good Linux support (OpenEmbedded) with source code, tools and documentation available, including support for the Robot Operating System (GumROS) for high level programming. They released the hardware early so that the community could work on the software, and there have been some good progress as you can see from the video below. You can already download the schematics and PCB layout file, but the software and instructions do not appear to be available […]

Nightly Builds for AllWinner A10 U-boot, Linux Kernel and Hardware Packs

Kent of SCUZ Technologies has graciously provided a build machine (Intel Xeon E5645) for Rhombus Tech (and possibly other) open source projects, and I’ve setup nightly build scripts for AllWinner A10 kernel, bootloader (u-boot) and hardware packs for Mele A1000 (HDMI), Mele A1000 (VGA), A10 mini PCs (using MK802 script.bin) as well as a server build for Mele A1000. The nightlies are built using  a10-hwpack-bld.sh script which is available in github, and can be downloaded from http://dl.linux-sunxi.org/nightly/ The resulting files are copied to a dropbox folder, until a better solution is found. For each build, you’ll find the following files : u-boot.bin – U-boot sun4i-spl.bin – U-boot SPL uImage – Kernel image product_YYYY.MM.DD.log (e.g. mele-a1000_2012.07.20.log) – The build logs whether the build succeeds of fails. One per hardware pack. product_hwpack_YYY.MM.DD.log ( e.g. mele-a1000_hwpack_2012.07.20.7z) – The hardware pack with the kernel, u-boot which can be used with a1x-media-create.sh script to create […]

TP-Link WR703N – $23 Hackable openWRT Wi-Fi 802.11N Router

TP-Link WR703N is a tiny 802.11N 150 Mbps Wi-Fi router smaller than a credit card (5.7 x 5.7 cm) and 1.8 cm thick based on Atheros AR7240 processor with 4 MB flash and 32 MB RAM. It costs just above $20 US and can be hacked with openWRT. It features one USB host connector that allows you to connect USB devices (USB flash drive, printer…) to it. TL-WR703N Specifications: Atheros AR7240 CPU @ 400Mhz (MIPS24k core) Atheros AR9331 Chipset (integrated wireless) 10/100 Mbit Ethernet port 802.11 b/g/n 150Mbps 3G support via external USB dongle 4 MB flash memory 32 MB RAM USB 2.0 port micro-USB port for power Dimension – 5.7 x 5.7 x 1.8 cm All you need is a USB to TLL board to access the serial console, open the box to access the serial pins (TP_IN and TP_OUT) and follow the instructions on openWRT website to convert […]

Building the Linux Kernel 3.0.8 For Telechips TCC8925 mini PCs (CX-01, Z900, TizzBird N1…)

Yesterday, we got Linux kernel 3.0.8 source code from Telechips, as well as some files related to Android 4.0 (Webkit + OMX). Today, I’ve had a look at the kernel source code and found a few very interesting things. First let’s get the code from github:

Good news! The code for the latest Telechips TCC892X is present in arch/arm/mach-tcc892x, and there is support for 3 types of boards: board-m805_892x – TCC8923 M805 board board-tcc8920 – TCC8920 evaluation board board-tcc8920st – TCC8920 STB evaluation board TCC8920 STB evaluation board appears to be relevant to products such as Diyomate A6, but if it’s also used for TCC8925 HDMI Dongle such as CX-01 mini PC, Zero Devices Z900 or ValuePlus TizzBird N1. Now let’s have a look at the default config directory for arm (arch/arm/configs):

Nice! tcc8925st_dongle_defconfig and tcc8925st_donglehs_defconfig look particularly interesting! A quick comparison shows that the only difference is […]

Raspberry Pi Releases Raspbian SD Card Image Based on Debian Wheezy ARMHF

The Raspberry Pi foundation announced the very first stable release of the Raspbian distribution, which is based on Debian 7.0 “Wheezy” armhf rootfs in order to take advantage of the FPU in Broadcom BCM2835. This distribution offers up to 40% performance improvement on several tasks, and for some specific tasks such as MP3 encoding is can boost the speed by nearly 6 times thanks to hard-float support. It is now the recommended distribution for the Raspberry Pi, runs LXDE environment, and comes with Midori browser, development tools and example source as per the previous Debian distros. omxplayer by gimli (XBMC developer) is also pre-installed in the image, and will allow you to play videos using hardware acceleration. You can download Raspbian via: Bittorrent – 2012-07-15-wheezy-raspbian.zip.torrent HTTP –  2012-07-15-wheezy-raspbian.zip The default credentials are pi / raspberry. Adam Armstrong has run some benchmarks to compare Raspbian (armhf) with the previous Raspberry Pi […]

Telechips Releases Linux Kernel 3.0.8 and Android ICS Source Code

Telechips has just uploaded the GPL source code for kernel 3.0.8 and Android 4.0 to the open source section of their website. If downloading from telechips website is too slow, you can also try alternate downloads (Thanks Gabe!): Kernel-3.0.8.tar.gz Ics.tar.gz I’ve also created 2 repositories in github: telechips-linux – Linux kernel source code telechips-android – Android platform open source code (webkit + OpenMAX source code) It haven’t looked into the source code in details yet, but hopefully, this will allow developers to customize the firmware running on Telechips TCC8925 based mini PCs such as CX-01 mini Android TV Box or Zero Devices Z900.
