Wi-Fi Performance Comparison for Android Media Players and HDMI Sticks

If you’re mainly using your Android mini PC or STB to stream videos over the web or your local network, Wi-Fi performance is actually more important than CPU performance, and I’ve recently had quite a few issues with Wi-Fi with both T428 (RK3188 / Broadcom Wi-Fi module) and CS868 (AllWinner A31 / Realtek Wi-Fi module), which were only fixed after upgrading my router firmware. So I’ve decided to re-test most of the mini PCs I own with the upgraded router firmware, and the number are highly confusing, and I found out there’s probably be no easy to way to estimate the overall Wi-Fi performance of any device, and it’s most probably highly dependent on the router used, and its firmware version. My router is TP-LINK WR940N, a 300 Mbps Wireless N router with three antennas. Since I bought it, I had never upgraded the firmware (3.9.18 Build 100104 Rel.36350n) from […]

2013 Embedded Market Study – Software Development & Processors

UBM releases a study of the embedded market every year, by surveying over 1,000 embedded professional every year. They’ve just published their 2013 Embedded Market Study (85 pages report), after surveying over 2,000 engineers and managers, so let’s see whether anything has evolved in the software development and processor space compared to 2012. Again this year, most respondents are based in the US (62%), followed by Europe (20%), and Asia (12%). C/C++ languages still rule the embedded world with 81% market share, although a little less than last year (85%), assembler is a distant third (5%). Interestingly, the average size of development teams seems to have shrunk from 15.9 in 2012 to 14.6 in 2013, the average project being composed of 4 software engineers, 2.9 hardware engineers, 2.7 firmware engineers, 2 QA/Test engineers, 1.5 system integrators, and 1.5 with other functions. About a third of project last less than 6 […]

$329 Texas Instruments OMAP5432 EVM / Development Board

Earlier this month, Texas Instruments has apparently discreetly, not to say surreptitiously, launched their OMAP5432 evaluation module. Beside the dual Cortex A15, dual Cortex M4 OMAP5 SoC, the board comes with 2GB RAM, a 4GB eMMC module, USB 3.0, SATA and more. OMAP5432 EVM Specifications: SoC – Texas Instruments OMAP5432 Multicore ARM Cortex A15/M4 processor with PowerVR SGX544MP2 GPU System Memory – 2GB DDR3L (implemented using 4x Micron 4Gb DDR3L devices (MT41K256M16HA-125:E) Storage – 4GB EMMC/iNAND Ultra device + SD/MMC 4-bit Micro-SD card cage Display / Video: HDMI via native OMAP HDMI interface DSI Display Expansion (DSIPORTA and DSIPORTC) via 100-pin expansion connector Parallel Display Expansion (DPI) via 100-pin expansion connector Audio – Audio Jack 3.5mm, Stereo out & in, Headset Jack (earphone/microphone) USB – 3x USB HS 2.0 (2 via USB connector, one via 0.1″ header), 1x USB 3.0, and 1x USB OTG 2.0/3.0 Connectivity – 10/100 802.3u Ethernet.

Linux-based $99 Ceptor HDMI Stick Powered by Freescale i.MX 6Dual

Thanks to individuals developers, we’ve been able to get Linux distributions based on Ubuntu, or Debian run on HDMI TV dongles for about a year, but nearly all of them just come with Android and that’s it. The only two exceptions I can think of are PengPod Pengstick and FXI Technologies Cotton Candy, where actively work on Ubuntu support, and provide images to boot from microSD. But now, Devon IT has developed a mini PC, called Ceptor powered by Freescale i.MX 6Dual processor with 1GB RAM, and up to 32GB Flash. It runs Linux-based ZeTOS operating system, and is destined at creating virtual desktop solutions for the enterprise. The casing just looks like HiaPad Hi802 or Zealz GK802 , but the internal specifications are slightly different: SoC – Freescale i.MX 6Dual @ 1 GHz + Vivance GC2000 GPU System Memory – 512MB or 1GB DDR3 Storage – up to 32GB eMMC […]

Debian 7.0 Installer for Hi802 / GK802 mini PCs

We’ve had Ubuntu support on i.MX6 HDMI dongles, specifically HiApad Hi802 and Zealz GK802, for a little while, but for those who prefer Debian distribution, a Debian installer is now available thanks to Angus Gratton. Bear in mind that 2D/3D GPU acceleration is disabled in order to save 192MB RAM, as this image is mainly destined to server and/or robotic applications. If you need a desktop experience with GPU acceleration, you’d have to use Ubuntu, or you may try enable it in Debian, and see if it works, but this has not been tested. The instructions below are to be used with the internal microSD card, but if you’re ready to hack a bit around, it might be possible to run the installer from an external microSD or USB device thanks to Jasbir’s U-boot multiboot. You’d still need to use an internal microSD, but you’d only have to open the […]

The First Jolla Phone Running SailFish OS is Now Available for Pre-order

After a teaser tweet in July 2012, Jolla officially announced Sailfish OS in November 2012, and today, they’ll announce the first Jolla Smartphone, which is available for pre-order. Key features of the Jolla smartphone: SoC – Dual core processor Storage – 16GB Flash + microSD Display – 4.5” Estrade display Camera – 8MP auto-focus rear camera Network – 4G Battery – User-replaceable battery The device will run gesture based Sailfish OS, and you’ll be able to run Android apps. For a closer look, have a look at the teaser video. One caveat if that the smartphone should only be available at the end of 2013, and, at the beginning at least, only in Europe. The phone will cost 399 Euros including (24%) VAT, but you can pre-order today via 3 options: 100 Euros voucher – Jolla phone + other half (apparently a customizable shell) + priority pre-order status 40 Euros […]
