How to Extract a Device Tree File from Android Firmware Files

Up to now, all our cheap Android devices were based on older Linux kernel (3.0.x, 3.4.x) that still used board files (arch/arm/board, but we’ve recently seen companies like Amlogic and Rockchip release source code with Linux kernel 3.10.x. One of the key differences between these version are the move from board files to flattened device tree and multi-platform support. If it is fully implemented, a single kernel image should be able to boot multiple hardware platforms, and all low level configuration handled by the device tree file. Since I’ve connected the serial port of Tronsmart Vega S89 for debugging, and it’s a slow news day, I thought I might try to boot the Linux kernel I compiled myself, but one of the challenge was to get the device tree file. I’ll show how to extract it from the firmware. It should also be possible to get it directly from the […]

Snapdragon 600 based IFC6410 Development Board is Available for $75 For a Limited Time

Despite their popularity with tablets and smartphones, I don’t see much developer community around Qualcomm Snapdragon processor, and only a few low cost development boards. One of them is Inforce Computing IF6410 pico-ITX board powered by Qualcomm Snapdragon 600 (APQ8064) quad core processor with 2GB RAM, 4GB eMMC flash, Gb Ethernet, Wi-Fi, Bluetooth, SATA, micro HDMI and LVDS video outputs, etc.., that normally sells for just $149. But the company is having a promotion for $75 with the coupon code “makerfaire” until May 18, or until the 500 units they’ve reserved are sold out. Shipping is not included in the price, and you’ll have to add about $50 for Fedex delivery (It may be cheaper in the US) for a total of about $125, which still probably makes it the cheapest “Cortex A15 class” board that you can get. The board appears to only officially support Android, and if you […]

Rikomagic MK902 II Android TV Box with Rockchip RK3288 Coming Soon

Rikomagic MK902 is an Android mini PC powered by Rockchip RK3188 quad core processor, and there’s even a Linux version. The company has announced it has been working on an upgrade of the device named MK902 II, and powered by Rockchip RK3288. It will initially sell with Android, but I would not be surprised with a PicUntu version is also sold later, and even an MK 902 II Chromebox could hit the market, since Rockchip released Chromium OS overlay files for RK3288. They’ve also provide MK902 II specifications: SoC – Rockchip 3288 quad core ARM Cortex A17 up to 1.8 GHz with Mali-T764 GPU System Memory – 2G DDR3 Storage – 8 or 16 GB flash + micro SD slot (up to 32GB) Video Output – HDMI, AV Audio Output / Input – HDMI, stereo audio (via AV port), optical S/PDIF, microphone Video Codecs – MPEG-1, MPEG-2, MPEG-4, H.263, H.264, […]

ARM Based COM Express Modules by MEN Mikro Electronik and Pactron

A few days ago, in a post listing different system-on-module (SoM) standards, I mentioned COM Express standard was targeting SoMs based on x86 processors, and SMARC was the equivalent for ARM. I still understand it’s the case as COM Express standard defines mechanical dimensions that are usually larger than SoM standard for low power processors, some buses found in ARM and x86 are different (e.g. AFAIK LPC and PCI are not found in ARM SoC), and the standard supports high power signals which are not needed in ARM or MIPS processors. Having said that, I’ve been pointed out to two ARM based COM Express modules, which could make sense if you want to use an ARM based module using existing COM Express compatible baseboards. The COM Express modules below feature Freescale i.MX6 and Marvell Armada XP SoCs, and have been designed respectively by MEN Mikro Electronik and Pactron. MEN Mikro […]

A Quick Test Drive of Tails, a Privacy Focused Linux Distribution

Tails (The Amnesic Incognito Live System) is a Linux distribution that allows you to use the Internet anonymously and circumvent censorship via the Tor network. It leaves no trace, and is said to use “state-of-the-art” cryptographic tools to encrypt files, emails and instant messages. It’s distributed as a live image that boots from a DVD drive, a USB stick, or an SD card. Tails v1.0 has recently been released. so let’s give it a quick try. Tails is currently only available for x86 (32-bit), no ARM image yet. The source code is available via a git repo. Let’s download the ISO image (mirror), and signature. Alternatively you can download both via BitTorrent. To make sure the image is not compromised it’s recommend to verify the integrity of the ISO image with the signature we’ve just downloaded. You’ll also need a signing key The are several methods, but I’ve opened a terminal, […]
