Embedded Systems Conference 2016 Schedule – April 13-14

The Embedded Systems Conference 2016 will take place in Boston on April 13-14, and the organizers have now released the schedule, minus some keynotes, which features four main tracks: Embedded Hardware, Embedded Software, Connected Devices and the Internet of Things (IoT), and the ESC Engineering Theatre. As usual, I’ve gone through the list of talks and composed my own little virtual schedule which ended up with sessions focusing on power management, IoT, and security, as well some optimization and drivers development talks among others, such as patents, and the origin of Gerber files. Wednesday 13 8:00 – 9:00 – Power Management in Embedded Systems by Colin Walls, Embedded Software Technologist, Mentor Graphics The importance of power management in today’s embedded designs has been steadily growing as an increasing number of battery powered devices are developed. In this session, we will discuss design considerations that should be made when starting a […]

How to Reduce SD Card Firmware Images Download Size

So I’ve just received a Roseapple Pi board, and I finally managed to download Debian and Android images from Roseapple pi download page. It took me nearly 24 hours to be successful, as the Debian 8.1 image is nearly 2GB large and neither download links from Google Drive nor Baidu were reliable, so I had to try a few times, and after several failed attempt it work (morning is usually better). One way is to use better servers like Mega, at least in my experience, but another way to reduce download time and possibly bandwidth costs is to provide a smaller image, in this case not a minimal image, but an image with the same exact files and functionalities, but optimized for compression. I followed three main steps to reduce the firmware size from 2GB to 1.5GB in a computer running Ubuntu 14.04, but other Linux operating systems should also […]

ZTE ZX296702 Dual Core Cortex A9 SoC Boots Android in 10 Seconds with TuxOnice

ZTE XZ296702 is a dual core Cortex A9 processor with a Mali-400 GPU that targets Android set-top boxes and media players, and while Charbax filmed a video with ZX296702-AD1 development board at Linaro Connect HK, initial patchsets were recently submitted to the Linux ARM Kernel mailing list for XZ296702 SoC and the development board. There aren’t any product page for ZX296702 processor, so instead let’s have a look at the board’s specifications: SoC – ZTE ZX296702 dual core ARM Cortex A9 processor with Mali-400 GPU System Memory – 512 MB RAM Storage – 4GB flash + micro SD card Video Output – HDMI + AV (RCA) Audio Output – HDMI + Stereo audio (2x RCA) Connectivity – Ethernet and Wi-Fi USB – 2x USB 2.0 host ports Power Supply – 5V Considering the board is running Android 4.4, the specs are quite low end, however the developers claim to have […]

New Optimized Web Browser Released for the Raspberry Pi

If you’ve ever tried to use a Raspberry Pi to browse the web, you must have noticed how frustrating it can be due to the overall sluggishness of the system. But thanks to work by Collaborra, which optimized Epiphany Web browser for the Raspberry Pi, bringing features such as 720p HTML5 hardware video decoding (no flash support), faster loading and scrolling, etc.., the web browsing experience has much improved, although as you’ll see from the video below, it’s still not quite 100% perfect. The key modifications brought to Epiphany Web browser are listed below: More responsive UI and scrolling, even while loading a page Progressive tiled rendering for smoother scrolling Startup is three times faster Avoid useless image format conversions Better YouTube support, including on-demand load of embedded YouTube videos to make page load much faster Hardware decoding and scaling of videos (through gst-omx) Reduction of the number of memory […]
