If you’ve ever compiled the Linux kernel, you’ll know make menuconfig is the command line used to unset/set options, disable/enable modules in order to match your hardware and requirements. I used to simply browse in the menu to find the option, and just remember the correct path. Sometimes I just looked at .config to locate the option I needed, and the possible path in make menuconfig. The first time you use a new option it can be time consuming. But I’ve just found there is a better way via Google+. “/” is actually available in make menuconfig, just like it is in vi/vim. If you want to enable NFS server in your kernel, press “/”, and search for NFSD. It will show the list of results with “NFSD” strings. NFS server support is right at the top, and the path is shown to be File Systems->Network File Systems. The neat […]
Pidora 18 (Raspberry Pi Fedora Remix 18) Released
John Chiappetta, working for Seneca Centre for Development of Open Technology, has recently announced the release of Raspberry Pi Fedora Remix 18, which will be now known as Pidora 18. If you were there at the time of Raspberry Pi Fedora Remix 14 release, the first ever Linux distribution released for the Raspberry Pi, you may remember it had many issues, and the Raspberry Pi foundation decided to remove it from their Download page. This fourth release will hopefully fix many issues, and they’ll end up back on Raspberry Pi site. Based on the Changelog vs R-Pi Fedora Remix 17, Pidora 18 features look promising: Almost all of the Fedora 18 package set available via yum (thousands of packages were built from the official Fedora repository and made available online) Compiled specifically to take advantage of the hardware already built into the Raspberry Pi Graphical firstboot configuration (with additional modules […]
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 […]
Win Enterprises MB-60830 Single Board Computer Powered by AMD Embedded G-Series SoC
At the end of last month, AMD announced their first Embedded SoC family that combines a CPU, a GPU, and a controller hub into one chipset. Win Enterprises is one of the first companies to release a board based on the platform with MB-60830, a single board computer powered by AMD G-Series dual core or quad core SoCs. The board is designed for embedded applications such as digital signage, gaming, medical imaging, kiosks/POS, thin client and factory automation. The board specifications are as follows: SoC – AMD Embedded G-Series SoC dual or quad core. System Memory – 1x DDR3 @ 1600MHZ / SODIMM up to 4GB Storage – 1x SATA 6.0 Gb/s, 1x Half-size Mini-PCIe supporting mSATA for SSD Connectivity – Intel i211 AT Gigabit Ethernet Video Outputs: 1x VGA 1x dual channel 24-bit LVDS 1x HDMI with Optional Chrontel CEC Support Digital I/O – 8-bit programmable LPC – 1x […]
$69 Linux Powered Arduino Yún Board is Designed for the Cloud
Massimo Banzi announced the Arduino Yún, the first of a family of Wi-Fi products combining Arduino with Linux, at the Maker Faire Bay Area. The company used the name Yún (云), meaning “cloud” in Chinese, as the purpose of this board to allow connection to web services directly from Arduino. Arduino Yun Specifications: MCU – Atmel ATMega32u4 @ 16 MHz (same as the one used in Leonardo board) with 2.5KB SRAM and 32KB flash SoC – Atheros AR9331 MIPS-based Wi-Fi SoC running Linino, Arduino’s own Linux distribution based on OpenWRT. It’s the same chipset as in TP-Link WR703N router. Storage – microSD card slot USB – micro USB connector + full USB host port Connectivity – Ethernet + Wi-Fi 14 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs) Arduino Yún ATMega32u4 can be programmed as a standard Arduino board by plugging it […]
