Adding Wi-Fi to Emcraft Systems K70 SoM

Emcraft Systems K70 SoM is a system-on-module powered by Freescale K70 Cortex M4 micro-controller with enough RAM (64 MB) to comfortably run uClinux. They used to charge $99 for their uCLinux BSP, but it’s now free of charge, and the company also provides full hardware and software documentation, including a getting started guide, schematics and BoM for the baseboard, application notes and more… Many of their clients want to use Wi-Fi with K70 SoM, and it can easily be done by using Wi-Fi USB dongles based on Ralink RT5370 chipset such as D-Link DWA-140 (H/W rev B3) or Comfast CF-WU815N. Emcraft has provided detailed instructions to do so with K70 SoM, their latest baseboard (SOM-BSB-EXT) and a demo image based on their uClinux BSP. I’ll summarize the instructions to use K70 SoM as a Wi-Fi access point below. Connect the baseboard and K70 SoM with an Ethernet cable, a mini […]

Nvidia Tegra 4 Benchmarks on Tablet Reference Design

Mobile World Congress 2013 has just started. Nvidia is showcasing both a smartphone reference platform based on Nvidia Tegra 4i (Phoenix reference phone) and an unnamed tablet reference design with Tegra 4 during the event, and several Android benchmarks have been run on the platform including Antutu and Quadrant. The results in the quad-core Cortex A15 Tegra 4 are really impressive with over 36,000 in AnTuTu and 16,000 in Quadrant, which are the best scores ever reported (by far) on those two benchmarks, as the top score in Antutu achieved with an overclocked Galaxy Note 2 is just over 27,000, a phone like the HTC One X scores around 5,600… Android Police also ran two other benchmarks that can help to access web browsing performance: Vellamo (HTML5) and SunSpider. The Tegra 4 completes SunSpider in 494ms (vs 1124ms with HTC One and 208ms in my desktop PC), and scores 3300 […]

ISEE Introduces IGEP COM CYGNUS & AQUILA Powered by TI Sitara AM335x Processor

ISEE will officially launch and showcase 2 new computers-on-module at Embedded World 2013 on February 26-28, in Nuremberg, Germany: IGEP COM CYGNUS and IGEP COM AQUILA. Both CoM shares the same characteristics except the former is powered by TI Sitara AM3352 (Cortex A8, no GPU) and the later by TI Sitara AM3354 (Cortex A8 + PowerVR GPU). This makes the CYGNUS suited for cost sensitive applications such as industrial control, home automation, and test and measurement devices, and the AQUILA for applications that requires more advanced graphics and multimedia capabilities such as gaming, auto infotainment and navigation devices. The key specifications of the 2 modules are as follows: Processor – Texas instruments Sitara AM3352 Cortex A8 @ 720 Mhz (CYGNUS) and AM3354 Cortex A8 @ 720 Mhz + PowerVR SGX GPU (AQUALIA) System memory – 256 MB DDR3 SDRAM, 303 MHz, 16-bit Storage – 128 MB SLC NAND FLASH + […]

Final Release of Fedora 18 for AllWinner A10 & A13 Powered Devices

A few months ago, Hans de Goede, currently working at Red Hat and a Fedora contributor, started to show up on linux-sunxi mailing list, and sent a lot of kernel patches for linux-sunxi kernel. Last week-end, he  announced “Fedora 18 Final for Allwinner A10 and A13 based devices” on linux-sunxi community mailing list. To install it, first download the image:

And write it to an SD card (all data will be wiped out):

You may have to replace “/dev/mmcblk0” by your own SD card device, e.g. “/dev/sdc”. AllWinner based devices can share the same kernel, but u-boot is board/products specific, so you’ll have to install u-boot for your board. First remove the SD card, re-insert it in order to automatically mount the FAT partition, and run:

This will show the list of supported boards and products. Then run the command again for your device. For example:

A New, Faster, and Cheaper Beaglebone is On its Way

Beaglebord.org community is currently teasing a new Beaglebone on their website. At this time information is not complete, but we already know it will be “significantly cheaper” than the existing Beaglebone, feature a processor with higher performance (Albeit the picture shows TI Sitara AM3359 which is about the same as AM3358 + Ethercat), and come with 512 MB DDR3L RAM (instead of 256 MB DDR2), 2GB eMMC Flash, and onboard HDMI output. The new Beaglebone will keep supporting Angstrom, Ubuntu and other Linux distributions. Hardware expansion boards (cape) designed for the old model will still be fully compatible with the new Beaglebone. You’ll need to wait April to get hold of the new Beaglebone. Until then, you can register your interest on Element14/Farnell to be informed when the board becomes available. Another way to find out more is to attend the Embedded Linux Conference 2013 which is taking place right […]

SILICA Pengwyn Low Cost Open Industrial Development Platform Powered by Sitara AM3354 Processor

At the end of January, SILICA, an Avnet subsidiary, announced the Pengwyn, a single board computer based on Texas Instruments Sitara AM3354 Cortex A8 processor. The board targets industrial customers, and the company promotes it as “an open platform to develop applications under Linux or Windows Embedded operating systems”. Here are the specifications of the Pengwyn board: Texas Instruments Sitara AM 3354 ARM Cortex-A8 MCU @ 720 MHz System Memory – 256 MB DDR3 Storage – 1 GB Nand Flash, 32 MB SPI Flash Memory, and microSD slot (if not used with Wi-Fi/Bt modules) Connectivity and expandability USB Host and Device Ports RJ-45 Ethernet Port Connector for optional 1 GB Ethernet Port 2x connectors for generic expansions modules SDIO/MMC Port (can be used for optional WI-FI/bluetooth modules) DVI Display Port Silica will provide Linux (Arago Project, an OpenEmbedded based Distribution) and Windows Embedded Compact 7 BSP and images, as well as […]

Canonical Unveils Ubuntu on Tablets

Yesterday, Ubuntu.com displayed a time counter for an announcement reading “Tic Toc Tablet Time” that ended being about Ubuntu on Tablets, and not an HTC Tablet running Ubuntu as some blogs speculated, as both companies had a timer counter set to expire at the same time for separate, and unrelated, announcements. The interface looks very much like Ubuntu for Phones with a similar “Welcome Screen”, except multiple users are supported, no icons (except for apps), and you can swipe around the 4 edges to access the dash, opened applications, notifications, and more. Canonical highlights 5 key features for Ubuntu on Tablets: Real multitasking – Run mobile and tablet apps at the same time on the same screen Secure multi-user Voice controlled HUD productivity Edge magic for cleaner apps – As I said previously no buttons, you control eveything from the edges. Content focus – Messages and media are easily accessible […]

Electronics Shop in Thailand – What Will $33 Buy?

Since I was in urgent need for a 5V/3A power adapter, I decided to go shopping locally (in Chiang Mai, Thailand) at some computer shopping malls, where they also have some spare parts. We spent about 1h30 visiting around 10 shops with no success: most of them did not have 5V power supply for sale, and those who did, could only provide 5V/2A power adapters. Finally, one guy at a shop was very helpful, and tried to help us without success, but finally  he said you should go to “Amorn“, and after driving a few kilometers we got there. When I entered the shop  I started to see some pretty interesting equipments: multi-meters, full sized oscilloscopes from 11,000 Bath (~370 USD), electronics cards for appliances (ventilators washing machine, car audio, amplifiers…), soldering irons, ribbon cables, components (capacitors, but no resistors), and much more. It turns out “Amorn Electronics Center” has […]
