Linux 3.16 Released

Linus Torvalds announced the release of Linux Kernel 3.16 over the week-end: So nothing particularly exciting happened this week, and 3.16 is out there. And as usual (previous release being the exception) that means that the merge window for 3.17 is obviously open. And for the third time in a row, the timing sucks for me, as I have travel coming up the second week of the merge window. Many other core developers will be traveling too, since it’s just before the kernel summit in Chicago. So we’ll see how the next merge window goes, but I’m not going to worry about it overmuch. If I end up not having time to do all the merges, I might delay things into the week of the kernel summit, but I’ll hope to get most of the big merging done this upcoming week before any travel takes place, so maybe it won’t come […]

Forlinx OK335xS-II is a Low Cost Linux and Wince Industrial Board Powered by TI Sitara AM335x Processor

Forlinx Embedded, a company based in Baoding, Hebei, China specializing in embedded systems design and manufacturing, has recently launched OK335xS-II single board computer powered by Texas Instruments AM335x SoC which they claim to be “the cheapest industrial Cortex-A8 board in history” as it sells for as low as 298 RMB or about $48.

Texas Instruments Announces Sitara AM437x Cortex A9 SoCs and Evaluation Modules

The first time I heard about Texas Instruments Sitara AM437x was via a TechNexion EDM-CT-AM437x system-on-module back in 2012, but Texas Instruments Sitara Cortex A9 processors development seems to have dragged a little longer than expected. Nevertheless, the company has now formally announced their Sitara AM437x ARM Cortex A9 SoC targeting automation, IoT gateways, and other industrial applications, and featuring four PRUs (Programmable Real-time Units), and support for dual camera for terminals with bar code scanning. At launch there will be four AM437xprocessors: AM4376, AM4377, AM4378, and AM4379. The processors will all be based on a single Cortex A9 core  @ 800 to 1000 MHz with 64KB SRAM shared with 32KB data cache and 32KB programmable cache, 256 KB L2 and L3 caches, a 32-bit memory interface supporting LPDDR2, DDR3, and DDR3L, a 2-port Gigabit Ethernet switch , two USB 2.0 OTG + PHY and the following other interfaces: Serial Ports […]

Emtrion DIMM-AM335x SoM Supports Mainline Linux Kernel

When I cover system-on-modules (SoM), companies will usually provide some BSP (Board Support Packages) for older kernels, and did not submit their changes to mailine kernel, so I was interested in a news from Emtrion entitled “DIMM-AM335x: Linux mainline support ready“, which actually means they’ve done the work to support a recent Linux kernel (3.14) and provides instructions and code (device tree files), but did not submit patches to the linux-arm-kernel mailing list to get their changes added to kernel.org. Let’s look at the hardware specs first: SoC – Texas Instruments Sitara AM335x ARM Cortex A8 processor @ 720Mhz to 1GHz (AM3354 or AM3359) System Memory – onboard 512 MB SDRAM/optional 256 MB Storage – 512 MB NAND Flash (managed) + 2 SD card interfaces Display – LCDs I/F with resolution up to SVGA, with 4-wire touch interface Audio – Analog Audio with SSI I/F USB – USB 2.0 Host […]

The BeagleBone Black Turns Blue with BlueSteel-Basic, Loses HDMI and Flash

CircuitCo has just introduced BlueSteel-Basic, a development board based on the Beaglebone Black but with a Blue PCB, no HDMI output, and no eMMC flash that’s destined to be used by OEMs in their products. LinuxGizmos also reports that BlueSteel-Basic is to be followed by BlueSteel-IT, an industrial temperature grade (-40 to 100°C) board based on the Beaglebone Black, and Bluesteel-Core, a computer-on-module (CoM) based on Ti Sitara AM335x that are scheduled for July 2014. Let’s checkout BlueSteel-Basic specifications: SoC – Texas Instruments Sitara AM3358BZCZ100 @ 1GHz (2000 MIPS) with PowerVR SGX530 3D GPU (20M Polygons/S) System Memory – 512MB DDR3L @ 800MHz Storage – micro SD slot Connectivity – 10/100M Ethernet (RJ45) USB – 1x USB 2.0 host port, 1x mini USB 2.0 port Debugging – Serial header and optional on-board 20-pin CTI JTAG Expansion Connectors Signals: Power 5V, 3.3V, VDD_ADC (1.8V) 3.3V I/O On All Signals McASP0, SPI1, […]

Qiyang Technology ARM Development Boards Based on Atmel SAMA5D3, TI Sitara AM335x and Freescale i.MX6 SoCs

Hangzhou Qiyang Technology (杭州启扬智能科技有限公司) is a company based in Hangzhou, China, that provides embedded hardware solutions such as low power development boards and computer-on-modules. I’ve recently come across the company, and they have boards for various ARM based SoCs, but I’ve received details about three of their latest industrial development boards powered by Atmel SAMA5D3 Cortex A5 processor, Texas Instruments Sitara AM335x Cortex A8 SoC, and Freescale i.MX6 single and multi-core ARM Cortex A9 SoCs. Let’s have a look. Qiyang QY-A5D3XEK – Atmel SAMA5D3 Development Board The development kit is comprised of a base board (IAC-A5D3X-MB) and a computer-on-module (ICA-A5D3X_CM) with the following hardware specifications: Processor – Atmel SAMA5D3 ARM Cortex A5 @ 536 MHz (Either SAMA5D31, SAMA5D33, SAMA5D34 or SAMA5D35) System Memory – 256 MB DDR2 @ 333 MHz Storage – 256MB NAND flash + 2MB dataflash on CoM, 2x SD card slot on baseboard Video Output – VGA, […]

Linux 3.15 Released

Linus Torvalds announced the release of Linux Kernel 3.15 last Sunday: So I ended up doing an rc8 because I was a bit worried about some last-minute dcache fixes, but it turns out that nobody seemed to even notice those. We did have other issues during the week, though, so it was just as well. The futex fixes and cleanups may stand out, but as usual there’s various other random fixes since rc8 in there too: mainly drivers (drm, networking, sound, usb etc), networking, scheduling and perf tooling. But it’s all been fairly small and quiet, which *may* of course be due to the fact that last week was also the first week of the merge window for 3.16. That might have distracted some developers. I’m not entirely convinced I liked the overlap, but it seemed to work ok, and unless people scream really loudly (“Please don’t _ever_ do that again”) and give good […]

Texas Instruments Releases Zigbee Home Automation Gateway Reference Design Based on BeagleBone Black

Texas Instruments has recently release a complete Linux based Zigbee home automation gateway based on BeagleBone Black development and CC2531 Evaluation Module Kit hardware which you can purchase for about $100 in total, and including Z-STACK Ubuntu gateway installer, as well as Z-STACK Home, a ZigBee Home Automation (ZHA 1.2) compliant protocol stack for the company’s CC2530 and CC2538 SoCs. I won’t go into details about the BeagleBone Black as I have already covered it into details previously. However, the hardware has slightly changed since the initial release, as the 2GB eMMC has now been replaced by a 4GB eMMC, and price has been increased to about $55. CC2531 evaluation module kit is comprised of CC2531 USB Dongle which you can connect to the USB port of a PC, or in this case a BeagleBone Black, for 802.15.4 / ZigBee applications. TI also provides CC2531 USB Firmware Library on their site to let developers […]
