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 […]

Star Cloud PCG02U Ubuntu TV Stick Unboxing and Teardown

Star Cloud PCG02U is one of the rare device selling pre-loaded with Ubuntu 14.04, and MeLE, who owns Start Cloud brand, sent me one sample for review. While many Android & Windows devices can be “hacked” to run Linux distributions such as Ubuntu, Star Cloud PCG02U is the first device that I’ve ever received that’s actually shipped with Ubuntu 14.04. So it will be very interesting to find out how it performs, but today, I’ll check the device and its accessories, as well as the hardware design. Star Cloud PCG02 Unboxing The TV stick ships in a Ubuntu orange retail packaging with Star Cloud branding, and mention of Ubuntu and Intel. I had already published the specifications in my first post, a confirmation on the package is always good. The TV stick ships with a 5V/2A power adapter and multi-country plug adapters, a female to female HDMI adapter, a Quick […]

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:

echo "rootmydevice" > /proc/sunxi_debug/sunxi_debug

1	echo "rootmydevice" > /proc/sunxi_debug/sunxi_debug

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

MiQi Dual Boot Android & Ubuntu Development Board Crowdfunding Campaign Has Launched

MiQi is a development board using a form factor similar to Raspberry Pi boards, but based on a more powerful Rockchip RK3288 Cortex A17 processor combined with 1 or 2 GB. I had the change to test an early sample pre-loaded with a dual boot image with Android 5.1 and Lubuntu 14.04, and found it to be one the fastest sub $100 development board in Linux, behind Hardkernel ODROID-XU4, as well as better CPU & GPU performance compared to recent Android TV boxes based on Amlogic S905, Rockchip RK3368, and so on. MQMaker has now launched a flexible funding crowdfunding campaign on Indiegogo to raise funds for mass production. Let’s remind us of MiQi hardware specifications first: SoC – Rockchip 3288 quad core ARM Cortex A17 up to 1.8 GHz with Mali-T764 GPU supporting OpenGL ES 1.1/2.0 /3.0, and OpenCL 1.1 System Memory – 1 or 2G DDR3 depending on model Storage – 8 or 32 […]

VoCore2 WiFi IoT Module Features Mediatek MT7628AN Processor

When Vocore WiFi module launched in 2014 on Indiegogo, it quickly became popular as at the time it was hard to find cost effective and small WiFi modules with GPIOs, and its compact Ethernet dock solution was also a hit. The developer has now been working on VoCore2 for several months, and recently announced a beta testing program. Vocore2 preliminary specifications: SoC – Mediatek MT7628AN MIPS processor @ 580 MHz System Memory – 64 or 128 MB DDR2 Storage – 16MB NOR FLASH, 1x SDXC via I/O pins Connectivity – WiFi 802.11n 2T2R up to 300 Mbps with either 2 u.FL connector or 1 u.FL connector + on-board chip antenna (Max signal output >19.5dbm peak); 2x 10/100M Ethernet interfaces via I/O pins I/Os – About 30 GPIOs multiplexed with 3x UARTs, 1x I2C, 1x I2S, 1x reference clock, 1x USB 2.0, 1x PCIe 1.1, 1x high speed SPI (40Mbps max), […]

How to Run Ubuntu 16.04 Aarch64 (64-bit ARM) Cloud Images on Your Intel/AMD Linux Computer with QEMU

With the recent launch of several low cost Cortex A53 development boards, 64-bit ARM hardware is now pretty common and inexpensive, but if you want to run 64-bit ARM code on your x86 Linux computer, Riku Voipio, a software engineer working for Linaro, wrote some instructions to run Ubuntu 16.04 Aarch64 Cloud image in QEMU. Ubuntu cloud images are “the official Ubuntu images and are pre-installed disk images that have been customized by Ubuntu engineering to run on public clouds that provide Ubuntu Certified Images, Openstack, LXD, and more. ” So the instructions are also useful if you want to easily try such packages on 64-bit ARM platform. I’ve tried those instructions myself on my Ubuntu 14.04 machine with and AMD FX8350 processor, and they worked pretty well, and the only things I had to find out by myself was to install a recent version of qemu. First, we’ll need […]
