NanoPi NEO Board Gets Armbian Debian 8 & Ubuntu 16.04 with Linux 4.6 & 4.7 (Mainline), h3consumption Power Consumption Tool

We’ve been blessed with a wide range of low cost Allwinner H3 boards thanks to Shenzhen Xunlong Orange Pi and FriendylARM NanoPi boards. Recently, armbian developers have been focusing on NanoPi NEO board, and they’ve now released Debian Jessie and Ubuntu Xenial with Linux 4.6.7 and Linux 4.7.2. The latter is mainline kernel with some patchsets for Ethernet. You can download the Linux 4.6.7 based “beta” images from armbian NanoPi NEO page, and selected the “Vanilla” versions, then flash then one a micro SD card as you would normally do. Linux 4.7.2 based “experimental” images with USB OTG support and schedutil cpufreq governor can be found on the separate server in a temporary directory. Thomas Kaiser explains further: Ethernet and throttling are working (the latter not as efficient as with legacy kernel but at least it protects the SoC from overheating). Please note that all vanilla kernel images currently suffer from […]

PULPino Open Source RISC-V MCU is Designed for IoT and Wearables

lowRISC is not the only open source processor project based on RISC-V instructions, as researchers at ETH Zurich university and the University of Bologna have developed PULPino open-source processor based on RISC-V instructions set, optimized for low power consumption, and targeting wearables and the IoT applications. PULPino is a single core processor derived from the PULP project (Parallel Ultra-Low-Power Platform) featuring a quad core RISC-V SoC with new RI5CY Signal Processing ISA extensions designed by the universities. The core has an IPC (instructions per cycle) close to 1, full support for the base integer instruction set (RV32I), compressed instructions (RV32C) and partial support for the multiplication instruction set extension (RV32M). PULPino also features peripherals such as I2S, I2C, SPI and UART. PULPino has already been taped out as an ASIC in UMC 65nm at the beginning of the year, but the RTL code be run on Xilinx Zynq-7010 powered Zedboard, […]

Embedded Linux Conference 2016 and OpenIoT Summit 2016 Schedule

The Embedded Linux Conference 2016 and the OpenIoT summit 2016 will take place on April 4 – 6, 2016 in San Diego, California, and over 800 attended will meet including kernel & system developers, userspace developers, and product vendors. The Linux Foundation has recently published the schedule, so I’ve had a look at some of the talks, and designed my own virtual schedule to find out more the current development focus although I won’t attend. Monday April 4 10:40am – 11:30am – Linux Connectivity for IoT by Marcel Holtmann, Intel OTC There are many connectivity solutions that available for IoT. For example Bluetooth Low Energy, 802.15.4, Zigbee, OIC, Thread and others. This presentation will provide and overview of the existing technology and upcoming standard and how they tie into the Linux kernel and its ecosystem. 11:40 – 12:30 – BoF: A Million Kernel Boots and Counting by Kevin Hilman, […]

Rockchip RKi6000 Low Power WiFi SoC Showcased with IoT Demo Board

Announced last year, Rockchip RKi6000 SoC promised WiFi connectivity at Bluetooth 4.0 LE power consumption levels, and the company has recently showcased the technology with a demo board controlling four lightbulbs. The chart above shows Rorkchip solution can transmit data at 802.11b speeds (11 Mbps) while still keeping power consumption low at around 10mW, similar to BT LE, and good enough to run on batteries. Peak Tx and Rx power has gone up a little since the first announcement, as the company now claims 66mW @ 11 Mbps instead of just 60mW. While there’s basically zero information about the chip on Rockchip website, you may have noticed a QR code on the product brochure in Charbax video linking to Rockchip IoT Club, which you can join as long as you work for a company with a specific project in mind. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a […]

Linaro Connect 2016 Bangkok Schedule – March 7-11, 2016

Linaro Connect Bangkok (BKK16) will take place on March  7 – 11, 2016, and the schedule is now available for the 5-day event with keynotes and sessions. Whether you’re going to attend or not, it’s always interesting to check the schedule to find out what’s going on in terms of ARM Linux development. The five days will focus on work by different Linaro groups, but really sessions are mixed for any given day, and I’ve created a virtual schedule for each day with available information, as Linaro has become a little more closed to the outside than when it was launched a few years ago. Monday 7 – LITE (Linaro IoT & Embedded Group) 1400 – 14:50 – Evolution of the Reference Software Platform Project The Reference Software Platform lead project was introduced in Linaro Connect San Francisco 2015, and since then it evolved and matured with the completion of […]

Izitron I-SEN1 Environmental Sensors Board Works with XBee Modules

Embedded Systems Conference 2016 Schedule – April 13-14

The Embedded Systems Conference 2016 will take place in Boston on April 13-14, and the organizers have now released the schedule, minus some keynotes, which features four main tracks: Embedded Hardware, Embedded Software, Connected Devices and the Internet of Things (IoT), and the ESC Engineering Theatre. As usual, I’ve gone through the list of talks and composed my own little virtual schedule which ended up with sessions focusing on power management, IoT, and security, as well some optimization and drivers development talks among others, such as patents, and the origin of Gerber files. Wednesday 13 8:00 – 9:00 – Power Management in Embedded Systems by Colin Walls, Embedded Software Technologist, Mentor Graphics The importance of power management in today’s embedded designs has been steadily growing as an increasing number of battery powered devices are developed. In this session, we will discuss design considerations that should be made when starting a […]

SMA-Q Smartwatch Mini Review and Teardown

I had great hopes for SMA-Q smartwatch, as it features an always on color e-Paper display, a built-in heart rate monitor, and promised 30-day standby battery life, as well as being 30-meter water resistant. But last week, I found out that the latter did not mean waterproof, and instead the watch was rated IP65 that’s only good enough to wash hands and a little rain, but not showering let alone swimming. In the last week, I could play with the watch, and found some serious Bluetooth connectivity issues (with Iocean M6752 smartphone), and I was recommended to upgrade the firmware of SMA-Q watch, and after that my Bluetooth issue have somewhat improve, but everything pretty much went downhill, and the watch is now out of order, and shows no sign of life. So while I was expecting to write a full review, I’ll simply report with experience with the watch […]
