How to Upgrade Allwinner A80 OptimusBoard Firmware

After informing Allwinner I had some rather slow write speed (3MB/s) to the NTFS partition of my USB drive on my A80 OptimusBoard, they kindly provided a new compressed Android firmware image (sun9iw1p1_android_optimus_v1.2_20140930.img.7z) with some NTFS optimizations that can be downloaded from baidu (password: x2tz), mega.co.nz or simos.info (please only use this link, if the other two do not work as it’s a private website and monthly bandwidth may be limited). I vaguely remember tools like LiveSuit (Linux) or PhoenixSuite (Windows), and I ended up on sunxi-linux Livesuit wiki as I’m running Ubuntu 14.04 on my PC, but you should be able to flash the firmware with PhoenixSuite if you run Windows. The instructions below can also be used for other Allwinner based devices. First you need to install LiveSuit, and build Allwinner USB drivers as follows:

In order to use LiveSuit as a normal user, you also have […]

Tronsmart T2000 EZCast Pro Dongle Supports MHL, Split Screen, Improves Wi-Fi Performance

EZCast dongles, tiny HDMI streaming Wi-Fi stick with support for Airplay, Miracast, DLNA, and their own proprietary EZCast protocol first appeared about a year ago. I’ve reviewed a few including Tronsmart T1000 and MeLeCast S1, and found them to work relatively well, with some caveats, in Android. There’s now a new EZCast Pro wireless adapters that adds features such for four split screens display, conference control via web browser, and content broadcast to multiple screens, as well as improved wireless performance thanks to 2T2R Wi-Fi. Tronsmart T2000 is the first device I’ve heard of, that’s EZCast Pro capable.

CALAO Systems Introduces PInBALL Industrial Board Based on Raspberry Pi Compute Module

CALAO Systems has just launched an industrial single board computer (SBC) for professional Raspberry Pi developers called PiNBALL or, if you prefer, PAC-1210-S200-B2835-EXX…. The board is powered by the Raspberry Pi Compute Module, features interfaces such as two mini PCIe slots (for USB, I2C, GPIOs,…), fast Ethernet, HDMI, opto-isolated inputs and outputs, etc., +6 to +36V power input, and can operate in -20°C to +70°C temperature range. PInBALL industrial SBC specifications (Items marker with ‘*’ are optional, and depend on model): SoC / Memory / Storage  – Via Raspberry Pi Compute Module – Broadcom BCM2835, 512MB RAM, 4GB eMMC Flash. Other Storage – 1x 2Kb I²C EEPROM with EUI-48 MAC Address & 128 bit Serial Number (AT24MAC402).

TP-Link TL-WDR7500 (Archer C7) 802.11ac Router Review

With several new Android devices coming with the latest 802.11ac Wi-Fi, I decided I should buy a new router with AC1200 class or greater and Gigabit Ethernet support, and with a budget of $100. Xiaomi Mi Wi-Fi Mini router almost matched my requirements, but unfortunately only comes with Fast Ethernet ports. TP-Link Archer C7 selling for $96 Amazon US exactly matched my budget, and outmatched my requirements being an AC1750 router with 5x Gigabit Ethernet ports, and two USB ports. Since Amazon won’t ship to my location and shipping would have gone over budget, I expected to find it locally for a slightly higher price, but it ended up selling for over $200 here, allegedly because of a lifetime guarantee. Finally, I ended up buying TP-Link TL-WDR7500, the Chinese version of Archer C7 with 6 Wi-Fi antennas instead of 3, for $94.32 including shipping on Aliexpress. I’ll take some pictures […]

Firefly-RK3288 Development Board is Now Available for $189

Three days ago, a T-chip representative informed me privately that Firefly development board (Rockchip RK3288) would not be available on foreign websites, and that it was unclear when the board would be selling in China. So either I’ve been lied to, or there’s poor internal communication within the company, as they’ve now listed Firefly-RK3288 board on Taobao for 800 CNY (~$130), and it’s also available on GeekBuying for $159 including shipping, possibly by somebody unrelated to T-chip, especially there are only 3 units for sale. Let’s go the specifications that have slightly changed since the original announcement: SoC – Rockchip 3288 quad core ARM Cortex A12 / 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 – 2G DDR3 Storage – 16 GB eMMC flash + micro SD slot Video I/O HDMI 2.0 up to 3840×2160@60p VGA out (D-SUB connector) Dual MIPI, Dual LVDS and and EDP […]

Linaro 14.09 Release with Kernel 3.17 and Android 4.4.4

Linaro 14.09 has just been released with Linux kernel 3.17-rc4 (baseline), Linux 3.10.54 & 3.14.19 (LSK), and Android 4.4.2 & 4.4.4. Linaro has kept working on their member boards such as IFC6410 (Qualcomm), D01 (Huawei/Hisilicon), Ardnale (Samsung), and Juno (ARM). They’ve also announced they’ll change the tools to build GCC by using cbuild2 instead of cbuild1 for next release, and they’ve enabled a build with gcov (for code coverage analysis) which may mean they’ll work on reducing the kernel size by getting rid off unused code. I’ve also noticed the Arndale and Arndale Octa Ubuntu images are now based on Linux LSK with Mali GPU support since last month. Here are the highlights of this release: Linux Linaro 3.17-rc4-2014.09 GATOR version 5.19 updated topic from Qualcomm LT (ifc6410 board support) and HiSilicon LT updated Versatile Express ARM64 support (FVP Base and Foundation models, Juno) from ARM LT. updated Versatile Express […]
