MiTAC Announces 7-Star 64-Bit ARM Server Powered by Applied Micro X-Gene Server-on-Chip

After unveiling their GFX servers based on Marvell ARM Cortex A9 SoC at Computex 2012, Mitac announced their new 7-Star server at Computex 2013. This new server is based on Applied Micro X-Gene SoC featuring ARMv8 architecture, and is one of the first, if not the first, 64-Bit ARM server ever. The key features of Mitac Server are as follows: 18x Front-loaded Computing Blades in 4U (176mm x 440mm x 650mm) Server Blade Spec SSI uModule v1.0 complaint (1) ARMv8 compliant 64-bit SoC /blade (2) DDR3 DIMM slots, and (2) 2.5” SATA 3.0 HDD support (1) 10G SFP+ and (1) GbE port IPMI V2.0 compliant Pass-through Ethernet Module Chassis Management Hot-swap FAN and (2+1) RPSU support It will be available by the end of the year. That’s about all I know for now, but more information should eventually come up on Mitac 7-Star page. Via PC Perspective. Jean-Luc Aufranc (CNXSoft)Jean-Luc […]

Rockchip RK3188 Linux Source Code is Now Available

Good news! I’ve just read Rockchip RK3188 Linux source code has just been released via Rikomagic, and Alok Sinha, the main maintainer of RK3066 source code, has already imported into github, and we should soon see a PicUntu image for RK3188 mini PCs. Let’s have a look:

[Update: you may have to run “sudo apt-get install libc6-i386” before running make_kernel_ruikemei.sh below, as mkkrnlimg is a 32-bit binary] Usually, I immediately look into arch/arm/configs, but this time, there’s a “funny” script called make_kernel_ruikemei.sh, and .config already have some CONFIG_RK3188, so let’s run it:

After just over a minute, success!:

This kernel image is for Android only, and there’s a little work to modify it as a “pure” Linux kernel, so that it can be used to boot PicUnutu for RK3188. Let’s go back to arch/arm/configs, and we’ll find several RK3188 configs: rk3168_86v_defconfig rk3188_dongle_defconfig rk3188_ds1006h_defconfig rk3188_ds1006h_v1_0_defconfig rk3188_hotdog_defconfig rk3188_LR097_defconfig rk3188_magicwand_defconfig […]

Calxeda Showcases Aaeon and Foxconn ARM Servers at Computex 2013

ARM started to get involved in servers in 2011 with the announcements of Calxeda Energy Core, Marvell, and Applied Micro X-Gene Servers-on-a-Chip, and in 2012, products made by companies such as HP and Mitac  started to appears. We’ve got to see some more ARM based servers this year thanks to Charbax, who filmed some Aaeon and Foxconn servers powered by Calxeda EnergyCore quad core ARM Cortex A9 SoC at Computex 2013. The first server is Aaeon Indus 1U cloud storage appliance: 1U Chassis 2x Calxeda Energycore nodes 10x 3.5″ HDD 2x 10 GbE uplinks and 4x 10GbE chassis-to-chassis interconnects Foxconn server shown at Computex has slightly higher specs: 4U chassis 12 Calxeda Energycore nodes 60x 3.5″ HDD for up to 240TB storage 4x 10 GbE uplinks and 6x 10 GbE chassis-to-chassis interconnects for 100 GbE total bandwidth There’s also a Gigabyte server, but I could get details.

Bluetooth Versions Walkthrough, and Bluetooth 4.0 Low Energy Development Resources

I’ve seen more and more Bluetooth 4.0 LE devices in the last few months including RFDuino, Wimoto Motes, TI SensorTag, and Scadanu Scout, so I thought it would be good to write a bit about Bluetooth. First, I’ll write about the different version of Bluetooth, since I was still confused with the practical implications between the versions, and then I’ll show some development kits and software resources to play around and/or develop Bluetooth 4.0 LE applications both on devices and hosts. Bluetooth Versions Bluetooth v1.0 and v1.0B The Bluetooth 1.0 Specification was released in 1999, and according to an entry in Wikipedia, 1.0 and 1.0B devices had many issues, mainly interoperability issues. You won’t find any Bluetooth 1.0 device today. Bluetooth v1.1 Bluetooth v1.1 was ratified as IEEE Standard 802.15.1-2002 in 2002. It fixed many issues found in the previous specifications, added the option to use non-encrypted channels, as well […]

Emcraft Systems STM32F4 SoM and Starter Kit Run uCLinux From On-Chip Flash

Emcraft has recently announced a new system-on-module based on STMicro STM32F437 Cortex M4 micro-controller, as well as a starter kit based on the module that can run uCLinux directly from STM32F437’s 2MB on-chip flash, allowing a faster boot time, and AFAIK, this is the only Linux-ready STM32 platform available on the market. Here are the specifications of Emcraft Systems SOM-STM32F4: MCU – STMicro STM32F437 Cortex M4 @ 168 MHz with 256KB RAM and 2MB flash External Memory – 16MB PSRAM External Storage – 16MB NOR Flash Ethernet PHY (Optional) Connectors – 2x SoM Connectors with access to I/Os: USB, Ethernet, I2C, SPI, UART, LCD I/F, ADC, DAC, GPIO… Dimensions – 30 mm x 46 mm To speed-up development and for evaluation, the company also provides a starter kit composed of the STM32F4 SoM, and a baseboard (SOM-BSB-EXT) with the following main features: USB interface using USB-UART bridge connected to UART […]

Critical Link MityARM-5CSX CoM Powered by Altera Cyclone V SoC

Earlier this week, I wrote about EnSilica eSi-ZM1, a system-on-module based on Xilinx Zynq7000 Extensible Processing Platform that comes with a dual core ARM Cortex A9 and FPGA fabric. It turns out Xilinx is not the only game in town, and Altera’s Cyclone V SoC, announced last December, also includes a dual core ARM Cortex A9 processor with Altera FPGA logic, and Critical Linux recently announced MityARM-5CSX computer-on-module based on this platform. Target applications include machine vision, scientific imaging, motor control, medical imaging and instrumentation, test and measurement, industrial instrumentation, as well as a military & aerospace. MityARM-5CSX specifications: SoC – Altera Cyclone V SX-U672 with FPGA logic and dual-core ARM Cortex-A9 up to 800MHz System Memory – 1GB DDR3 RAM, and 256MB DDR3 FPGA RAM (optional) Storage – 32MB QPSI NOR flash FPGA I/O fabric: PCIe  hard core Up to 145 user-programmable I/O lines (including several 875MHz SerDes lanes) […]

Gumstix Alto35 Customizable Touchscreen Board

A few months ago, Gumstix introduced Geppeto, a web platform that allows you to design and order your own baseboard for Gumstix Overo systems-on-module within minutes. The company has just announced Alto35, an expansion board built entirely with Geppetto. The Alto35 replaces Palo35 Overo-series expansion board with the same features, but adding the possibility of customizing the board via Geppetto. Alto34 expansions board features the following: 3.5″ LCD resistive touch screen Stereo audio in/out jacks 3D accelerometer (STMicro LIS33DE) RC servo USB – 2x USB mini-B ports, including console port (FT232RQ USB UART) LEDs in 4 different colors, 2 tactile switches. 2×70-pin AVX Headers compatible with Overo COMs. Power – 3.5V-5V All Overo computers-on-module are compatible with Alto35 board, so you can just use existing software solutions such as Linaro Ubuntu, Robot Operating System, and the Yocto Project. Alto35 is available for $89 including the display (not the Overo module), […]

$25 Texas Instruments SensorTag is a Bluetooth LE Devkit with 6 Sensors

Yesterday, I wrote about Wimoto Motes, tiny Bluetooth LE devices with several sensors that can be controlled and monitored via an iOS app, and soon by an Android app, as well as Linux devices. Each mote costs $39 plus shipping, and one commenter mentioned the price may be a bit too high. A Google search for “bluetooth sensor” immediately brings TI SensorTag, which looks somewhat similar, except it is a Bluetooth LE development kit, includes 6 sensors (but no light sensor), and only costs $25 including shipping. SensorTag Specifications: Bluetooth 4.0 low energy (CC2541) SoC 6 sensors connected via I2C: IR Temperature sensor (TI TMP006) Humidity sensor (Sensirion SHT21) Pressure sensor (Epcos T5400) Accelerometer (Kionix KXTJ9) Gyroscope (InvenSense IMU-3000) Magnetometer (Freescale MAG3110) Power – Single cell coin cell battery (CR2032), quiescent current consumption of 8uA, allowing years of battery life.
