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:

If you just boot to […]

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:

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:

and armhf:

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 […]

How to Use Libhybris and Android GPU Libraries with Mer (Linux) on the Cubieboard

You may have heard about libhybris, a library that cleverly loads Android HW adaptations and convert calls from bionic to glibc. One of the greatest achievement of this library is to allow Android GPU drivers to be used with Linux, and is notably used by Canonical, although they did not write it, for Ubuntu 14.04 which will be compatible with any recent Android smartphones or tablets. One way to get started with libhybris is to port a device to Ubuntu Touch, but this may take a while. However, I’ve found a faster and easier way to play with libhybris thanks to Martin Brook (vgrade) who wrote a tutorial on how to use libhybris with Mer on the Cubieboard. Mer is an open source mobile Linux distribution powered by Qt/QML and HTML5, that’s born from the ashes of Meego, and is now used in the upcoming Sailfish OS. You’ll need to […]

Payter NFC Watch Can Be Used to Make Payments, for Identification, and More

The first time I heard about NFC was when it was implemented in Android 2.3, and the Google Nexus S featured it, but it’s quite older than that, as the initial specifications were published in 2006, and the very first phone to feature the technology was Nokia 6131. If you’ve ever been to Hong Kong, you may have used Octopus cards which are used for contactless payments for public transport and shopping. Those cards use Felica RFID technology which is part of NFC, and has also been included in some watches (since 2010), so you can easily pay for subway or bus by hovering your watch on the card reader. I’ve been wondering why I could not see more of those, and I think NFC may be a feature of upcoming smart watches, so I started to look for existing solutions this morning, and found Payper NFC Watch designed by […]

Watch and Record Live TV on Android or iOS Mobile Devices with Geniatech WiTV

If you’ve ever wanted to watch live digital TV on your tablet or smartphone, there’s now a solution. Geniatech WiTV is a tiny battery powered DVB receiver also acting as Wi-Fi access point in order to stream live TV to your mobile devices. You can use this device within your house or on the go, but it has to be within 5 to 7 meters from your tablet or smartphone to work properly.

Mele Android Set-Top Boxes At China Sourcing Fair 2013

The Mele A1000 and A2000 based on AllWinner A10 have been relatively popular last year, and recently Mele A1000G Quad has been unveiled with AllWinner A31 quad core Cortex A7 processor, and there was talk about a  Dual core version as well. Charbax has shot 3 videos at Mele stand at China Sourcing Fair in Hong Kong earlier this month, so I’ve got a bit more news to share. The first video shows the Mele A1000G Quad with a 2.4Ghz remote (which must be Mele F10 Fly Mouse). We don’t really learn much more than we already know,  but we can see the device is action with a 3D game controlled with the “Fly Mouse”, and the new “Metro” style user interface. This STB is currently running Android 4.1, but an upgrade to Android 4.2 is expected in June. The device will be available in May for about $110 retail, […]
