AMLogic Releases AML8726-MX Linux 3.0.8 Source Code

While doing a Google search to locate the open Linux page of AMLogic, I noticed another link reading “Amlogic AML8726-MX Linux kernel code released“. Interesting. So AMLogic appears to have released the kernel source code for their latest dual core Cortex A9 processor at the beginning of August and the tarball is available from their open source site: kernel-common-2012-08-03-git-a63244fb9c.tar.gz. A github user (fards) also imported the code to github, but he’s not affiliated with AMLogic, so don’t expect commits from AMLogic there. Let’s retrieve it:

git clone git://github.com/fards/AMlogic_Meson6_030812release.git

1	git clone git://github.com/fards/AMlogic_Meson6_030812release.git

AML8726-MX is codenamed MESON6 in the source code, and the code is in arch/arm/mach-meson6/, but let’s see if we can find a config file in arch/arm/configs. Yes! There are 4: meson6_android_defconfig – Android config file (Single core) meson6_defconfig – Linux config file (Single core) all Android config disabled. meson6smp_android_defconfig – Android config file with smp (symmetric multiprocessing) support meson6smp_defconfig – Config file with smp […]

MIPS Releases Android 4.1.1 (Jelly Bean) Source Code

At the end of last month, MIPS announced the $125 Karbonn Mobiles Android Jelly Bean Tablet powered by Ingzenic MIPS-Based JZ4770 SoC. Today, they released Android 4.1.1 source code for MIPS Before downloading the Android source code, make sure you have a properly setup Linux workstation. Here are the instructions to checkout MIPS Android 4.1.1:

mkdir mipsandroid
cd mipsandroid
repo init -u  git://github.com/MIPS/manifests.git -b dev-mips-jb -m mips-jb-4.1.1_r1.xml
repo sync

mkdir mipsandroid

cd mipsandroid

repo init -u git://github.com/MIPS/manifests.git -b dev-mips-jb -m mips-jb-4.1.1_r1.xml

repo sync

You can read the release notes for more details about the current status of the MIPS Android Jelly Bean port. Myriad Dalvik turbo, an alternative Dalvik implement that is much faster than the default Dalvik engine (at least on MIPS), is not yet available for Android 4.1, but should be soon. All MIPS Android source code can also be viewed online at http://www.github.com/mips.

VIA Releases Kernel 2.6.32 and U-Boot Source Code for $49 APC Board

VIA Technology unveiled the low cost APC (Android PC) board based on WonderMedia WM8750 processor (ARM11) back in May, and started to ship the Android board this month (I think since that was their plan). The company has just released Kernel 2.6.32.9 and U-Boot source on github. Here’s how to retrieve the code provided git is already installed on your machine:

git clone git://github.com/apc-io/apc-8750.git

1	git clone git://github.com/apc-io/apc-8750.git

You can then build U-Boot (provided you’ve already installed an ARM toolchain in your path):

cd $CURRENT_PATH/u-boot
make wmt_config
make all

cd $CURRENT_PATH/u-boot

make wmt_config

make all

and the Linux kernel:

cd $CURRENT_PATH/kernel
make 8710_defconfig
make ubin

cd $CURRENT_PATH/kernel

make 8710_defconfig

make ubin

The availability of the source means we should see Linux distribution like Debian, Fedora or Arch Linux ARM (separate from Arch Linux) running on the board very soon. In theory, it’s also possible to run a Linux distribution with the binary Linux kernel compiled for Android, but it causes some issues and also makes customization more difficult. I think they should also have release the code they modified […]

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:

git clone git://github.com/cnxsoft/telechips-linux.git

1	git clone git://github.com/cnxsoft/telechips-linux.git

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):

ls | grep tcc89
tcc8920st_defconfig
tcc8920st_hdb892s_defconfig
tcc8925st_dongle_defconfig
tcc8925st_donglehs_defconfig
tcc8925st_hdb892f_defconfig
tcc8925st_isdbt_module_defconfig
tcc892x_defconfig

ls | grep tcc89

tcc8920st_defconfig

tcc8920st_hdb892s_defconfig

tcc8925st_dongle_defconfig

tcc8925st_donglehs_defconfig

tcc8925st_hdb892f_defconfig

tcc8925st_isdbt_module_defconfig

tcc892x_defconfig

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

ARM TechCon 2012: Software & System Design Schedule

ARM Technology Conference (TechCon) 2012 will take place on October 30 – November 1, 2011, in Santa Clara, and UBM Electronics has already posted the detailed schedule for the event. The first day (October 30) will be Chip Designs day and the other 2 days will focus on Software & System Design. Even if, like me, you are not be able to go there, it’s still interesting to know what will be discussed at the conference, to have a better idea where ARM is going, and what new technologies and/or development techniques are (or will become) available. There will be around 70 sessions categorized in 15 tracks: Android / Open Source – Development tools, middleware for native application development, and optimized drivers for Android, Linux, FreeRTOS etc … Compute Platforms – Development and implementation of standards and specifications, from board/module design to consumer and server designs Developing / Debugging – […]

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.

webOS Community Edition Release for HP TouchPad

Open webOS 1.0 is planned to be released in September 2012, but in the meantime, the development team has released an intermediate webOS “Community Edition” for the HP TouchPad. This code is different from the Open webOS project, and is composed of additional components from the current release of webOS for the TouchPad. The open webOS project team has been working with WebOS Internals to bring this release out for legacy TouchPad devices. Thanks to the release of the webOS Community Edition, it is now possible to learn how the TouchPad works, modify your TouchPad experience and then apply that to Open webOS 1.0 once it is released. The Community Edition only supports HP TouchPad, whereas Open webOS 1.0 release will enable the community to port webOS to different hardware platform, and add more features by using open source stacks such as BlueZ bluetooth and GStreamer. You’ll need to download […]

Collabora and Fluendo Release GStreamer SDK 2012.5 Amazon

Last week, Collabora and Fluendo jointly announced the release of an open source software development kit (SDK ) for GStreamer multimedia framework. The SDK aims at easing the integration of Gstreamer into projects and provides a pre-built version of the framework which is available for Linux, Windows and Mac OS X. GStreamer is used in many Linux applications such as media players (Rhythmbox, Banshee and Amarok), video editors (PitiVi), and media centers such as XBMC among other applications. It’s also often the framework used to play videos on ARM platforms with implementations for OMAP 4/5 and devices compliant with the OpenMAX standard. Gstreamer website has also been updated and provides links to download GStreamer SDK and documentation on the home page. The new documentation looks pretty good with fives main sections: Instructions for installing the SDK on Linux (Ubuntu, Debian and Fedora), Windows or Mac OS. 11 basic and 2 advanced tutorials. […]
