Virtual reality has gotten a lot of hype in the last year or so, and so far there’s basically three ways to implement virtual reality: smartphone + VR headset, all-in-one headset, and PC + headset. Currently the former is the most popular option as it’s much cheaper than the other two, while PC based virtual reality provides the best user experience, but it’s quite pricey. Allwinner is now at Computex 2016 promoting their virtual reality solutions, and they see smartphone based VR peak in 2018, PC based VR have a slower growth, with All-in-one VR becoming the dominant force in 2020 and beyond. So the company is focusing on all-in-one Android VR headsets, starting with H8vr board featuring Allwinner H8 octa-core processor with 2GB RAM and 16GB storage, and mainly targeting 4K virtual reality videos, since the performance of current mobile processors does not really provide a good experience for […]
Allwinner News – Root Exploit in Linux and Fake Pine A64 Boards
There’s been a lot of buzz about a root exploit in Linux 3.4 kernel for Allwinner H3/H83T SoCs found by linux-sunxi & armbian developers in the last few days. Since the kernel for H3 / H83T is stuck to 3.4, and not always updated on the vast majority of hardware platforms, it’s quite likely there are many ways to breach into such systems, and even the majority of Android devices are not secure, not only the ones powered by Allwinner. So I did not really pay attention at first, but it went viral with stories reporting a hidden backdoor, and hitting to ill-intent. But is that really the case? That’s the code from github, now removed from the master branch, but still in A83T branch. It’s now super easy to gain root access by simply running one command which works for any users:
1 |
echo "rootmydevice" > /proc/sunxi_debug/sunxi_debug |
That’s obviously pretty bad, but is […]
Sub $100 Remix OS Laptops Powered by Allwinner A64 Processor Are Coming Our Way
Remix OS is a fork of Android making the popular operating system more suitable for desktop use with a start-up menu, better handling of multi-tasking, multi-window support, etc… It’s found in several tablets and TV boxes including Jide’s own Remix mini. But Charbax has showcased a few Remix OS laptop prototypes based on Allwinner A64 processor, with the video apparently shot from Allwinner office. The first model is a white 11.6″ laptop (1366×768) with Allwinner A64 quad core Cortex A53 processor, looking quite similar to Olimex DIY laptop prototype also based on A64, with 1 to 2GB RAM, 8GB to 32GB flash, and a “nice keyboard and touchpad”. The second model is based on the hardware, except the screen is larger (14.1″). It features HDMI output, two USB 2.0 ports, a micro SD slot, and a 3.5mm audio jack. Those two models are expected to sell between $80 and $100 […]
Linux 4.5 Released – Main Changes, ARM and MIPS Architectures
Linus Torvalds released Linux Kernel 4.5 on Sunday: So this is later on a Sunday than my usual schedule, because I just couldn’t make up my mind whether I should do another rc8 or not, and kept just waffling about it. In the end, I obviously decided not to,but it could have gone either way. We did have one nasty regression that got fixed yesterday, and the networking pull early in the week was larger than I would have wished for. But the block layer should be all good now, and David went through all his networking commits an extra time just to make me feel comfy about it, so in the end I didn’t see any point to making the release cycle any longer than usual. And on the whole, everything here is pretty small. The diffstat looks a bit larger for an xfs fix, because that fix has […]
Allwinner A64 Android 5.1 SDK and Linux Source Code
Allwinner A64 is likely to become quite popular as it will be used in PINE A64 board, Olimex open source hardware laptop featuring A64-OLinuXino board, and some low cost tablets. We’ve already got some documentation such as Allwinner A64 datasheet and user’s manual, but AFAIK, there was no source code released for the board. The good news is that you can now download Android 5.1 SDK and Linux source code on Baidu with four files available: lichee_A64_A5.1_V1.0.tar.gz – Linux source code android_A64_A5.1_V1.0.tar.gz– Android 5.1 SDK android_prebuilts_A64_A5.1_V1.0.tar.gz – Some pre-built binaries for Android A64硬件资料.zip – Documentation including the datasheet, product brief, and user’s manual which we’ve already got, but also some hardware with reference schematics, PCB layout files, and BoM for an Allwinner A64 tablet. That’s about 7.4GB to download, and apart from the documentation, the download is not quite complete yet, so I could not look into the details of […]
Allwinner A64 Datasheet and User Manual Released
Allwinner has two 64-bit ARM processors in the works: Allwinner H64 and Allwinner A64. Both are quad core Cortex A53 processors with a Mali-400MP2 GPU, H.265 4K video playback with basically the same interfaces and peripherals, but H64 also supports H.264 at 4K resolutions, while A64 is limited to H.264 @ 1080p, and H64 adds a TS interface. The first good news is that two boards are in development: Orange Pi Plus 3 with Allwinner H64 Olimex A64-OLinuXino update with Allwinner A64 Engineering samples have already been produced for the first board, but that’s about all the information we have now, as Shenzhen Xunlong has not built its reputation by releasing documentation early. One the other hand, A64-OLinuXino schematics have nearly been completed, but we already know more details, as not only Olimex boards are open source hardware, but the company defies conventional wisdom by involving the community in the […]
Linux 4.3 Release – Main Changes, ARM and MIPS Architectures
Linus Torvalds released Linux Kernel 4.3 last week-end: So it *felt* like the last week of the rc series was busy, to the point where I got a bit worried about the release. But doing the actual numbers shows that that really was just my subjective feeling, probably due to the kernel summit and travel back home from Korea. It wasn’t actually a particularly busy week, it’s just that the pull requests were more noticeable in the last couple of days. We had a network update and a late fix for a x86 vm86 mode bug introduced by the vm86 cleanups, but other than that it’s just a collection of various small one-liners all over. Ok, the vm86 mode thing was a one-liner too, it was just slightly more nerve-wracking because it looked scarier than it was before people (Andy) figured out what was going on. The changes from rc7 […]
$64 Allwinner V3 Action Cameras Support 4K Video Recording (or Not?)
An “Allwinner V3 4K Ultra HD DV Sport Camera” just appeared in GeekBuying product feed which the company sells for $84.39, and searching for alternative sellers led me to Soocoo F60 4K action camera sold for $63.34 on GearBest. Both cameras look the same, and the price appears amazing cheap as 4K cameras such as GoPro Hero4 or Sony X1000V normally sell for $500 and more. But one of the tricks is that both “4K” cameras are likely based on Sunchip 4K camera design, which does support 4K video recording, but only at 15 fps. Soocoo F60 camera specifications: SoC – Allwinner V3 ARM Cortex A7 processor @ 1.2GHz System Memory – N/A Storage – micro SD card up to 64GB Display – 2″ LCD Camera OmniVision OV4689 image sensor (4MP according to sensor page, but 16MP on camera description, probably achieved with extrapolation). 170-degree wide angle Recording time up […]
