PlayJam GameStick is a video game console comprised of an AMLogic powered mini PC and a wireless game controller. They had a successful kickstarter campaign with 5,691 backers, and the company started to ship developer’s kits earlier this month. Those kits are designed for developers, and is not the final hardware which, as Liliputing reports, will be available in June for $79. The retail version of the GameStick will feature a smaller stick with mini USB port (instead of a full USB port in the devkit), and a controller with a better finish. In the meantime, PlayJam has uploaded an unboxing video of the development kits, showing the mini PC, controller and accessories (cables, power supply, etc..), as well as a quick demo. The demo shows the first boot setup (language, display layout, ethernet, Wi-Fi settings), the Gamestick store, and they play a RipideGP. If you’re a game developer, you can […]
Using ARM Development Studio 5 (DS-5) Streamline with MK802II mini PC
MK802-II is an Android 4.0 mini PC powered by AllWinner A10 (ARM Cortex A8) with 1GB RAM and 4GB flash. Instructions are also available to run Ubuntu, or other Linux distributions. ARM Development Studio 5 (ARM DS-5) is software development tool suite for ARM processors that can be used for both Linux and Android debugging, and available in 2 versions: professional edition and community edition, the latter being free of charge. I’m writing about both today, because Bob Peng, Technical Marking Engineer for ARM China, recently wrote a blog post in Chinese [Update: An English version is now available] showing how to use MK802-II, preloaded with the required drivers and daemon, with DS-5 Streamline Performance Analyzer with is part of both versions. The community edition may be missing some features of Streamline however. Streamline Performance Analyzer allows you to: Find out which modules or functions to take up most of […]

STMicro STiH416 Dual Core Media Processor and Linux SDK
STMicro announced STiH416 SoC for media players at CES 2012 with very few details, but we’ve still known that it is a dual core Cortex A9 @ 1.2 GHz coupled with a quad core Mali-400 manufacturer and an hardware video decoder supporting commonly used codecs such as H.264, VC-1, AVS and MPEG2. Yesterday they put out a press release about a STB development platform based on this solution, and I found out we’ve got much more information now.

You-Get – Video Download Script for YouTube, YouKu, DailyMotion, and More
YouKu is the equivalent of YouTube in China, and earlier today I wanted to download a video from the service, so I’ve looked for an application or script that can do the job in Linux. I’ve finally come across you-get, a python 3 script that claims to be able to download videos from an impressive number of websites, namely: YouTube Vimeo Coursera Blip Dailymotion Facebook Google+ Google Drive Tumblr Vine SoundCloud Mixcloud Freesound JPopsuki VID48 Niconico (ニコニコ動画) Youku (优酷) Tudou (土豆) YinYueTai (音悦台) AcFun bilibili CNTV (中国网络电视台) Douban (豆瓣) ifeng (凤凰视频) iQIYI (爱奇艺) Joy.cn (激动网) Ku6 (酷6网) MioMio h NetEase (网易视频) (v.163.com) PPTV.com QQ (腾讯视频) (v.qq.com) Sina (新浪视频) (video.sina.com.cn) Sohu (搜狐视频) (tv.sohu.com) 56 (56网) Xiami (虾米) Baidu (百度音乐) (music.baidu.com) SongTaste I won’t try all, but just test it with YouKu and YouTube. First things first, let’s install it:

Booting Linux in Less Than 1 Second in AllWinner A10 Devices? Yes! You Can!
threewater, a Chinese developer, has just posted a very interesting demo on linux-sunxi mailing list showing a device based on AllWinner A10 boot linux within 0.85s, and if you add a Qt app, the total time is just about 1.2s. This appears to be a custom hardware (EM6000), but we do know it’s based on AllWinner A10, comes with 512 MB RAM, and 4GB NAND Flash. On the software side, the device runs kernel 3.4 from linux-sunxi, with a customized version of uboot, a squashfs rootfs, and a Qt 4.7.4 app showing a gauge. Both the rootfs (7MB) and the kernel (2MB) have been compressed with LZO. All that boots from NAND flash for optimal speed. The 1.2 second time includes kernel + rootfs + app time, and the total time is a bit longer, but this is still impressive. Here’s the boot log:

How to Detect if an ARM ELF Binary is Hard-float (ARMHF) or Soft-float (ARMEL)
If some cases you may want to know if a library or binary built for the ARM architecture is using hard-float (armhf) or soft-float (armel). You can analyze ELF binary using readefl utility, so let’s have a try. First let’s install some armel and armhf files on a computer running Ubuntu by install gcc/g++ toolchain for armel and armhf:
1 |
apt-get install g++-arm-linux-gnueabi g++-arm-linux-gnueabihf |
We now have armhf and armel libraries installed in /usr/arm-linux-gnueabihf/lib and /usr/arm-linux-gnueabi/lib respectively. Let’s check the output of readelf filtered with “FP” string for libm.so.6 for armel:
1 2 3 4 5 6 7 |
readelf -a /usr/arm-linux-gnueabi/lib/libm.so.6 | grep FP Tag_FP_arch: VFPv3-D16 Tag_ABI_FP_denormal: Needed Tag_ABI_FP_exceptions: Needed Tag_ABI_FP_number_model: IEEE 754 Tag_ABI_HardFP_use: SP and DP |
and armhf:
1 2 3 4 5 6 7 8 |
readelf -a /usr/arm-linux-gnueabihf/lib/libm.so.6 | grep FP Tag_FP_arch: VFPv3-D16 Tag_ABI_FP_denormal: Needed Tag_ABI_FP_exceptions: Needed Tag_ABI_FP_number_model: IEEE 754 Tag_ABI_HardFP_use: SP and DP Tag_ABI_VFP_args: VFP registers |
Great, so there’s an extra line for armhf (Tag_ABI_VFP_args) that seems to confirm the library is hard-float. With readelf compiled from elftoolchain-0.6.1 (source code), the extra line will be a bit different: “Tag_ABI_VFP_args: AAPCS (VFP variant) AAPCS stands for ARM Architecture Procedure Call Standard. You can read more details on ARM website. There are also two other possible values […]
