Linux 4.6 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 4.6 earlier today: It’s just as well I didn’t cut the rc cycle short, since the last week ended up getting a few more fixes than expected, but nothing in there feels all that odd or out of line. So 4.6 is out there at the normal schedule, and that obviously also means that I’ll start doing merge window pull requests for 4.7 starting tomorrow. Since rc7, there’s been small noise all over, with driver fixes being the bulk of it, but there is minor noise all over (perf tooling, networking, filesystems,  documentation, some small arch fixes..) The appended shortlog will give you a feel for what’s been going on during the last week. The 4.6 kernel on the whole was a fairly big release – more commits than we’ve had in a while. But it all felt fairly calm despite that. Linux 4.5 added […]

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:

That’s obviously pretty bad, but is […]

Olimex A20-OLinuXino-LIME2-eMMC Board Replaces NAND by eMMC Flash for Better Performance & Reliability

A20-OLinuXino-LIME boards are the most popular development board sold by Olimex, likely thanks to reasonable pricing, and Allwinner A20 is one of the rare low cost processor to features an actual SATA interface and Gigabit Ethernet support. The company has now launched a new version A20-OLinuXino-LIME2-eMMC, based on A20-OLinuXino-LIME2-4GB, but replacing the NAND flash by an eMMC flash that should offer both better performance and reliability. A20-OLinuXino-LIME2-eMMC specifications: SoC – Allwinner A20 dual-core ARM Cortex-A7 CPU @ 1.0 GHz  with dual-core Mali 400 GPU System Memory – 1GB DDR3 Storage – 4GB eMMC flash (Micron), SATA data and power connectors, micro SD slot, 2KB EEPROM for MAC address and custom data Connectivity – Gigabit Ethernet Video Output – HDMI up to 1080p60 USB – 2x USB 2.0 host ports with power control and current limiter, 1x micro USB-OTG with power control and current limiter Expansion – 160 GPIOs on four […]

Chromium OS for SBC Aims to Turn Popular Development Boards into Chromeboxes

A team of developer has come together last December in order to provide Chromium OS, the open source project which Chrome OS is based on, to single board computers such as Raspberry Pi boards. So far, they’ve provided Chromium OS images for Raspberry Pi 2 & 3, but more boards should be supported in the future. The latest version 0.5 release is said to be usable, but WiFi, Netflix, and HTML5 video are not working. The installation procedure is standard. You simply need to download and uncompress the archive (e.g. SamKinison_v0.5_Pi3_16GB.tar.xz), and dump it on a micro SD card with Win32DiskImage or dd. They have released different images for Raspberry Pi 2 & 3, and different SD card sizes (2GB and 16GB). Chromium OS is using 12 partitions, so that may be why they don’t provide a single image and resize the file system during the first time. You can […]

PINE A64+ Board Giveaway

PINE A64 and A64+ board are incredibly inexpensive, but still not free, so when PINE64 asked if they could give eight PINE64+ boards with 1GB RAM and the WiFi & Bluetooth module to CNX Software readers, I thought it was not a bad idea, and I’ve decided to organize a giveaway. The eight boards given away will have the following specs: SoC – Allwinner A64 quad core ARM Cortex A53 processor @ 1.2 GHz with Mali-400MP2 GPU System Memory – 1 GB DDR3 Storage – micro SD slot supporting up to 256 GB Video Output – HDMI 1.4 up to 4K resolution @ 30 Hz, and 4-lane MIPI DSI connector and touch panel connector Audio – HDMI, 3.5 mm headphone jack Connectivity – Gigabit Ethernet + WiFi & Bluetooth module USB – 2x USB 2.0 host ports Camera – MIPI CSI camera interface Expansion – 40-pin Raspberry Pi 2 compatible […]

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 […]

Open Source Mali-200 / Mali-400 GPU Lima Driver Gets New Commits

The Lima driver, a project aimed at providing an open source driver for ARM Mali-400 and Mali-200 GPUs, was introduced 4 years ago, and after some reverse engineering work, a Quake 3 demo was showcase later in 2013 with an intermediate version of the Lima drivers. However, the main developer (libv) eventually lost interest or lacked time to further work, and the latest commit was made in June 9, 2013. But another developer (oklas) committed some code to limadriver-ng just a few days ago. But don’t get too excited, as the modifications are minor with some build fixes, some other Makefile modifications, and only one C file modified with 6 new lines of code. But maybe that’s just the beginning… We’ll see. Mali-400 GPU is now rather old, so why would somebody work on this? One explanation could be C.H.I.P and Pine A64 boards are both based on Allwinner SoCs […]
