Pine64 PADI IoT Stamp WiFi IoT Kit Review – Part 1: Hardware, Debuggers, and Soldering

Back in September, Pine64 unveiled their $2 PADI IoT Stamp based on Realtek RTL8710 ARM Cortex M3 WiFi SoC aiming to compete with Expressif ESP8266 solutions. The company has now sent me their complete kit for review, which beside the module itself includes a breakout board kit, and some hardware debug tools. In the first part of the review, I’ll check out the hardware, and solder the kit. I received a package with four antistatic bags. From top left to bottom right, we have PADI IoT Stamp, JLINK-OB debugger based on an STM32 MCU with some jumper wires (aka Dupont cables) for SWD signals, and a USB cable to your computer in order to flash the firmware or do some bare metal programming, a breakout board kit including two headers, a RED LED, and a resistor, and finally a USB to Serial board based on CH340G with 4 jumper wires […]

Intel Introduces 3 Atom E3900 Apollo Lake Processors for IoT, Industrials and Automotive Applications: x5-E3930, x5-E3940, x7-E3950

Intel previously introduced Celeron and Pentium Apollo Lake processors for laptops and mini PCs, and it seemed Atom was gone for good from that processor family, but the vendor has now introduced Atom E3900 “Apollo Lake” processor family for IoT, industrial and automotive applications with three models: x5-E3930, x5-E3940, and x7-E3950. All three new processors will support up to 8 GB of LPDDR4/DDR3L memory, come in a FCBGA1296 package, be manufactured using 14 nm process, support 4K UHD video output up to 60 Hz on three independent displays, up to 15 simultaneous 1080p30 video stream, as well as 13MP cameras for photos and 1080p60 video capture. Peripherals interfaces include SATA 3.0, PCIe lane, HDMI, DisplayPort, embedded DisplayPort, USB 3.0 & 2.0 ports and more. The new processors also integrate Intel Time Coordinated Computing (TCC) Technology that “coordinates and synchronizes peripherals and networks of connected devices, achieving improved determinism. It can […]

ARM Introduces Secure Cortex-M23 and Cortex-M33 ARMv8-M MCU Cores, and Bluetooth 5 Cordio Radio IP for IoT Applications

ARM TechCon 2016 is now taking place in Santa Clara, California, USA, as ARM has made three announcements for the Internet of Things, the focus of SoftBank going forward, with two ARM Cortex-M ARMv8-M cores integrating ARM TrustZone technology, namely Cortex-M23 low power small footprint core, and Cortex-M33 core with processing power similar to Cortex-M3/M4 cores, as well as Cordio Radio IP for Bluetooth 5 and 802.15.4 connectivity. ARM Cortex-M23 ARM Cortex-M23, based on the ARMv8-M baseline architecture, is the smallest and most energy efficient ARM processor with TrustZone security technology,and targets embedded applications requiring both a small footprint, low power, and security. Its power consumption is low enough to be used in batteryless, energy harvesting IoT nodes, and is roughly a third of Cortex-M33 processor size, and offers more than twice its energy efficiency. Cortex-M23 is a two-stage pipelined processor, software compatible with other processors in the Cortex-M family. […]

Canonical Livepatch Service Automatically Updates Ubuntu 16.04 LTS (and later) with the Latest Kernel without Rebooting

Installing or upgrading packages in Linux distributions does not normally require rebooting your system, except for the Linux kernel and drivers. But since Linux 4.0 kernel, Live Kernel patching is possible, meaning Linux kernel updates can be performed without having to reboot your server or computer. Canonical is now taking advantage of this new feature with their Livepatch Service available for Ubuntu 16.04 LTS and greater. If you want to enable it on your machine, you’ll have to authenticate to Livepatch portal to get a key / token for the service as shown in the screenshot above. Now you can install the service:

sudo snap install canonical-livepatch

1	sudo snap install canonical-livepatch

and enable it with your token:

sudo canonical-livepatch enable [your-token]
Successfully enabled device. Using machine-token: [your-token]

1 2	sudo canonical-livepatch enable [your-token] Successfully enabled device. Using machine-token: [your-token]

That’s it. Your can check Livepatch service status with the command:

canonical-livepatch status --verbose
client-version: "5"
machine-id: [your-machine-id]
machine-token: [your-machine-token]
architecture: x86_64
cpu-model: AMD FX(tm)-8350 Eight-Core Processor
last-check: 2016-10-25T19:35:55.009247615+07:00
boot-time: 2016-10-25T09:00:09+07:00
uptime: 10h52m7s
status:
- kernel: 4.4.0-45.66-generic
  running: true
  livepatch:
    state: nothing-to-apply
    version: ""
    fixes: ""

canonical-livepatch status --verbose

client-version: "5"

machine-id: [your-machine-id]

machine-token: [your-machine-token]

architecture: x86_64

cpu-model: AMD FX(tm)-8350 Eight-Core Processor

last-check: 2016-10-25T19:35:55.009247615+07:00

boot-time: 2016-10-25T09:00:09+07:00

uptime: 10h52m7s

status:

- kernel: 4.4.0-45.66-generic

running: true

livepatch:

state: nothing-to-apply

version: ""

fixes: ""

In my case, an update was not necessary, but if there’s one you should see something like:

livepatch:
    state: applied
    version: "12.2"
    fixes: '* CVE-2012-6828'

livepatch:

state: applied

version: "12.2"

fixes: '* CVE-2012-6828'

That way you can make sure your system always […]
