$25 GL.iNet 6416A is an Hackable OpenWRT Router with Easy UART and GPIO Access

There are plenty of low cost routers supporting OpenWRT, but GL.iNet 6416A has several advantages compared to devices like TP-Link WR703N. Both are based on Atheros AR9931, but GL.iNet router has more memory and storage (64MB RAM + 16MB Flash vs 32MB RAM + 4MB Flash), two Ethernet ports instead of just one, and 6 GPIOs, the serial pins, and power signals (5V, 3.3V and GND) are all easily accessible via though holes or headers. Gl.iNet 6416A can be purchased for about $25 on DealExtreme or Amazon US, and it used to be listed on eBay, but is now out of stock. Gl/iNET 6416A specifications: Wi-Fi SoC – Atheros AR9331 MIPS processor @ 400 MHz System Memory – 64MB RAM Storage – 16MB Flash Connectivity – 2x 10/100 Mbit Ethernet ports, 802.11 b/g/n Wi-FI up to 150Mbps USB – 1x USB 2.0 port, 1x micro USB port for power Debugging […]

Linux (Enlightenment and Lubuntu) in WeTek Play Amlogic TV Box

Last week I reviewed WeTek Play, a TV box with two DVB-S2 tuners, powered by Amlogic AML8726-MX dual core ARM Cortex A9 processor, and running Android 4.2, but the company also released several Linux based images including one with Enlightenment window manager, and another, temporary one, with Ubuntu core which allows you to install Lubuntu or Xubuntu with apt-get. There are also working on OpenELEC, but have not released the binary yet. Today, I’ll try the Enlightenment image because it also supports hardware video decoding via Gplay (gstreamer), and show how to install Lubuntu. The instructions below have been done in a computer running Ubuntu 14.04, but a Windows computer can also be used. Download Wetek-Linux.img.bz2 Connect a micro SD card to your computer, extract and flash Wetek-Linux.img: In Linux using a terminal window:

bzip2 -d Wetek-LInux.img.bz2
sudo dd if=Wetek-Linux.img of=/dev/sdd bs=1M
sync

bzip2 -d Wetek-LInux.img.bz2

sudo dd if=Wetek-Linux.img of=/dev/sdd bs=1M

sync

In Windows, extract the image, and use Win32DiskImager to copy the image to your micro SD […]

Interview with Allwinner Regarding their Linaro Membership

Since Allwinner has joined the Linaro Digital Home Group earlier this year, many people, including myself, have wondered what it means in terms of Linux support, and the engagement with the open source community. Following up on an idea from a regular reader, I’ve decided to asked a few questions to Ben-El Baz, marketing manager at Allwinner, and Linaro contact for Allwinner, which he kindly answered, and accepted to be published on CNX Software. CNXSoft: Why did Allwinner decide to join Linaro, and especially the Digital Home Group? Allwinner: One of our company’s goals is to be a technology leader. It’s ambitious but not too far-fetched given the background of our leadership and engineering team. There’s an extremely talented group of guys behind the scenes here! Leading is difficult unless you’re involved in collaborative organizations like Linaro that work on new technology. Joining Linaro is an opportunity for us to […]

Embedded Linux Conference Europe 2014 Schedule – IoT, ARM vs x86, Optimization, Power Management, Debugging…

The Embedded Linux Conference Europe (ELC 2014), CloudOpen, and LinuxCon Europe will jointly take place at the Congress Centre Düsseldorf, in Germany on October 13 – 15, 2014. The 3-day events will consists of keynotes, presentations, and tutorials. Each day will open with two or three keynotes by speakers including Jim Zemlin (Executive Director, Linux Foundation), and Jono Bacon (XPRIZE), followed by presentation and tutorials. There will be 45 presentations for ELCE, 58 for LinuxCon, and 47 for CloudOpen, I’ll make a virtual schedule with a few sessions part of the Embedded Linux Conference Europe “track”. Monday, October 13 11:15 – 12:05 – Performance Analysis Using the Perf Suite by Mans Rullgar, Consultant When faced with a performance problem, the initial steps towards a solution include identifying the sections of code responsible and the precise reasons they are time-consuming. To this end, the ‘perf’ profiling tools provide valuable insight into the […]

WRTNode is a Hacker-Friendly Open Source Hardware OpenWRT Wi-Fi Module Selling for $25

There are now some tiny and low cost ($15 to $20) Wi-Fi modules supporting OpenWRT such as VoCore and AsiaRF AWM002. However due to their small size they may not be that hacker’s friendly as they can’t have 2.54mm headers due to heir small size, and I’ve recently received AsiaRF AWM002 only to find out it not only needs 3.3V supply voltage, but also 1.8V and 1.2V. So I’d need to make my own power circuit with the required LDOs, or purchase a $20 base board to use the module. Here comes WRTnode another larger Wi-Fi module but with more usable 2.54mm headers, and based on the more powerful Mediatek MT7620N processor @ 600MHz. WRTnode hardware specifications: Processor – Mediatek MT7620N 600MHz MIPS CPU (MIPS24KEc) System Memory – 64MB DDR2 Storage – 16MB SPI flash Connectivity – Wi-Fi 2T2R 802.11n 2.4 GHz up to 300Mbps Expansion Headers – 2x with […]

Raspberry Pi Based Slice, and EzeeCube Quad Media Players Support Internal Hard Drives (Crowdfunding)

Slice is a media player based on Raspberry Pi Compute Module, and EzeeCube Quad is media hub powered by Freescale i.MX6 Quad, and an upgrade to EzeeCube based on i.MX6 dual, which was successfully funded. The underlying hardware between Slice and EzeeCube is much different, but both devices have a lot in common. They are both media players currently being crowd-funded respectively in Kickstarter and Indiegogo, both comes with an internal hard drive, run XBMC, targets typical end-users (rather than tinkerers) and are somewhat pricey. Slice Media Player When I first saw Slice, all I could see was an Raspberry Pi module, put in a case with an internal hard drive bay, and lots of pretty RGB LEDs, and with an air mouse sold for an inflated price of 114 GBP ($190 US) without hard drive or 179 GBP ($300 US) with a 1TB drive, with admittedly some cheaper early […]
