Raspberry Pi 2 / ODROID C1+ Development Boards Comparison

Raspberry Pi 2 Model B board has just been released, and although it’s not a direct answer to ODROID-C1, as Broadcom started the design for BCM2836 SoC for RPI2 a long time ago, both low cost development boards have similar specifications, with a quad core processor, 1GB RAM, Ethernet, and four USB ports, as well as the exact same price: $35. So I’ve decided to compare both in details to find out the actual differences, and which one may be more suitable to a particular application. Let’s get straight to the comparison table. [Updated on November 24 to use ODROID C1+ instead of ODROID C1] Hardkernel ODROID C1+ Raspberry Pi 2 Model B Comment Processor Amlogic S805 quad core Cortex A5 @ 1.5 GHz (Overclockable to 1.7 GHz or more) Broadcom BCM2836 quad core Cortex A7 @ 900 MHz (Overclockable to 1.1GHz or more) Despite the architecture advantage for Cortex […]

Raspberry Pi 2 Model B Features Broadcom BCM2836 Quad Core Processor

The Raspberry Pi foundation has finally released an upgraded version of the Raspberry Pi. Raspberry Pi 2 model B features much of the same ports and form factor as Raspberry Pi Model B+, by replaces Broadcom BCM2835 ARM11 processor  @ 700 MHz with a much faster Broadcom BCM2836 quad core ARMv7 processor @ 900 MHz, and with an upgrade to 1GB RAM. Raspberry Pi 2 Model B specifications: SoC – Broadcom BCM2836 quad core Cortex A7 processor @ 900MHz with VideoCore IV GPU System Memory – 1GB LPDDR2 (PoP) Storage – micro SD card slot (push release type) Video & Audio Output – HDMI and AV via 3.5mm jack.

FOSDEM 2015 Schedule – January 31 – February 1 2015

FOSDEM (Free and Open Source Software Developers’ European Meeting) takes place every year during the first week-end of February. This year the developer-oriented event expects to bring over 5000 geeks to share ideas and collaborate on open source projects. Contrary to most other events, it’s free to attend, and you don’t even need to register, just show up. FOSDEM 2015 will take place on January 31- February 1 in Brussels. There will be 551 sessions divided into 5 keynotes, 40 lightning talks, 6 certification exams, and with the bulk being developer rooms and main tracks,  divided into 7 main tracks this year: Languages, Performance, Time, Typesetting, Hardware, Security and Miscellaneous. I’m not going to attend, but it’s still interested to see what will be talked about, and I’ve concocted my own little virtual program out of the main tracks and developers’ rooms. There’s a few minutes overlap between some talks […]

Top 10 Posts of 2014 and Stats on CNX Software

Wow! After a slow start of the year, 2014 has been a busy year as new devices based on newer processor from Amlogic started to flood the market in Q2, soon followed by even more Rockchip RK3288 based media players, and then some more Amlogic S805 and Allwinner A80 boards and devices. It’s now the last day of the year, so just like in 2013, it’s time to look back on the main trends of the year, and based on the list of the top 10 most visited posts below, the new generation of ARM Android media players were the most important story of the year on CNX Software, but we also saw more IoT devices and board like Vidonn X5 or LinkIT One, lots of new Wi-Fi modules, and by the end of the year ESP8266 seemed to have won that fight, but being found in $3 Wi-Fi modules.

OpenELEC 5.0 Linux Distribution Released with Kodi 14

OpenELEC (Open Embedded Linux Entertainment Center) is a lightweight Linux distribution aiming at turning your computer or device into a Kodi media center. So instead of installing Kodi as a program or app on a desktop OS or Android, you could have a dedicated machine, which boots faster, has lower requirements (90-125 MB required for a full installation), and supported external tuners to watch live TV, as well as PVR & timeshifting functions out of the box. The developers have now announced OpenELEC 5.0 release, the successor of OpenELEC 4.2. Key changes for OpenELEC 5.0 include: Update from XBMC 13 (Gotham) to Kodi 14 (Helix) Update from Linux 3.16 to Linux 3.17 Switch from OpenSSL to LibreSSL Freescale i.IMX6 support for SolidRun CuBox-i, CuboxTV, and Hummingboard AppleTV support has been discontinued Beside build for the CuBox devices, OpenELEC 5.0 can be downloaded for x86 (32- and 64-bit builds), and the […]
