Samsung Introduces Artik 530 IoT Module & Development Kit with WiFi, BLE, and Zigbee/Thread

Samsung unveiled Artik 1, Artik 5, and Artik 10 IoT modules & development board families in 2015, but since then they dropped the Artik 1 family, and instead launched Artik 0, Artik 5, and Artik  7 modules and boards late last year. More recently the company canceled the more powerful Artik 1020 development board, but the Artik project is still going on, as they’ve just added Artik 530 module & development kit to their Artik 5 family. Samsung ARTIK 530 module specifications: SoC – Unnamed Quad core ARM Cortex A9 processor @ 1.2 GHz with a 3D graphics accelerator System Memory – 512 MB DDR3 Storage – 4GB eMMC v4.5 flash Connectivity – Dual band SISO 802.11 a/b/g/n WiFi, Bluetooth 4.2 LE + Classic, 802.15.4/Zigbee/Thread, 10/100/1000M MAC (external PHY required) Other Interfaces and peripherals Camera – 4-lane MIPI CSI up to 5MP (1920×1080 @ 30fps) Display – 4-lane MIPI DSI […]

Older Intel Atom C2000 Series Server Chips May Stop Working After a While, and There’s no Fix

It takes time and efforts to debugging hardware and software to get a product right, but some bugs may be hard to reproduce, or only happen over time, and it appears some Intel Celeron C2000 series processor for microservers may stop working after about 18 months, with the likelihood of problems increasing over time, due to clock signals that stop functioning. This is documented in Intel Atom Processor C2000 Product Family Specification Update, with Errata AVR 54 explaining the issue: AVR54. System May Experience Inability to Boot or May Cease Operation Problem: The SoC LPC_CLKOUT0 and/or LPC_CLKOUT1 signals (Low Pin Count bus clock outputs) may stop functioning. Implication: If the LPC clock(s) stop functioning the system will no longer be able to boot. Workaround: A platform level change has been identified and may be implemented as a workaround for this erratum. Status: For the steppings affected, see Table 1, “Errata […]

How to Assign Brightness Keys in Ubuntu 16.04 and Greater

Yesterday, I installed Ubuntu 17.04 in CHUWI LapBook 14.1, and was surprised everything appeared to work properly. However, the laptop does not come with brightness up and down keys. So I looked for ways to assign other keys to adjust brightness on the laptop, and eventually found a solution on AskUbuntu, and tried the options for Ubuntu 16.04. First we need to install xdotool, a utility that simulate keyboard input and mouse activity:

Once it’s done, go to the Dash, start Keyboard settings app, select Shortcuts tab, and click on the + icon on the bottom of the window to bring up the “Custom Shortcut” window. Now fill the Name field with “Brightness Up”, and the Command field with:

Repeat the procedure with for the down key filling the Name field with “Brightness Down”, and the Command:

Now we should have our two brightness keys, and we […]

Installing Ubuntu 17.04 on CHUWI LapBook 14.1 Apollo Lake Laptop

[Update: The instructions below do not work with the newly manufactured models because CHUWI completely changed the hardware The company also disabled the Linux option in the BIOS (See comments in this post) So you may need to use rEFInd boot manager or isorepin.sh script to install Linux (and some drivers may still not work out of the box) ] Since I’ve completed the review of CHUWI LapBook 14.1 with Windows 10 last week-end, I’ve decided to give it a try with a Linux distribution, and I chose to go with a daily build of Ubuntu 17.04 since we’ve seen Apollo Lake platforms need a recent Linux kernel. While Ubuntu 17.04 will be officially release in April 2017, likely with Linux 4.10, the current (alpha) build comes with Linux 4.9. I had already quickly booted Ubuntu 17.04 on the Laptop from a USB drive flashed using Rufus right after the […]

Oh Look… Espressif ESP32 Die-shot! That’s Pretty!

Espressif ESP32 was launched last year as a faster and upgraded version of ESP8266, with a dual core processor, 802.11 b/g/n WiFi and Bluetooth 4.0 LE. Boards based on the processor are still priced much higher than the ones based on ESP8266 ( although we’re only talking about $20 here), and shops have trouble keeping stocks, so either there’s a huge demand, there’s some manufacturing bottleneck, or maybe Espressif wants to take it slow at the beginning in case some hard to find bugs are found in the Silicon. Nevertheless, the guys at Zeptobar got hold of some ESP32 modules, and took some pretty die-shots. The die size is 2960×2850 µm. The prettiest part is clearly the RF section zoomed in below. If you wonder how it compares to ESP8266 die-shot, Zeptobar has you covered.

CHUWI LapBook 14.1 Apollo Lake Laptop Review – Part 2: Windows 10 Benchmarks, User Experience, and Battery Life

CHUWI LapBook 14.1 is the one of the first Apollo Lake laptop on the market. It features a 14.1″ IPS display, a Celeron N3450 quad core processor, 4GB RAM and 64 GB storage. The company has sent me a sample for review, and I had already check out the hardware in “CHUWI LapBook 14.1 Apollo Lake Laptop Review – Part 1: Unboxing & (Partial) Teardown“, so since then I’ve played with it including checking emails & news, writing a blog post on CNX Software, and watching some YouTube videos, as well as running benchmarks and estimating battery life, so I’ll report about my experience with the laptop in the second part of the review. CHUWI LapBook 14.1 System Information LapBook 14.1 runs an activated version of Windows 10 Home 64-bit on an Intel Celeron 3450 “Apollo Lake” quad core processor @ 1.1 GHz / 2.2 GHz with 4 GB RAM […]

Embedded Linux Conference & OpenIoT Summit 2017 Schedule

The Embedded Linux Conference 2017 and the OpenIoT Summit 2017 will take place earlier than last year, on February  20 – 23, 2017 in Portland, Oregon, USA. This will be the 12th year for ELC, where kernel & system developers, userspace developers, and product vendors meet and collaborate. The schedule has been posted on the Linux Foundation website, and whether you’re going to attend or not, it’s always informative to check out the topics. So as usual, I’ll make a virtual schedule for all 5 days. Monday, February 20 For the first day, the selection is easy, as choices are limited, and the official first day it actually on Tuesday. You can either attend a full-day paid training sessions entitled “Building A Low Powered Smart Appliance Workshop“, and the only session that day: 14:30 – 15:20 – Over-the-air (OTA) Software Updates without Downtime or Service Disruption, by Alfred Bratterud, IncludeOS […]
