Intel Xeon D network and edge processors find their way into COM Express & COM-HPC modules

Intel has recently launched the Intel Xeon D (Ice Lake-D) processor family with the D-2700 and the D-1700 models designed for software-defined network and edge applications with integrated AI and crypto acceleration, built-in Ethernet, support for Intel Time Coordinated Computing (TCC) and Time-Sensitive Networking (TSN), plus high reliability. The new processors are bringing data center-class hardware to the edge, and at least two embedded systems companies, namely ADLINK Technology and Congatec, have already launched COM-HPC server modules and COM Express Type 7 module based on the new Intel Xeon D family. Intel Xeon D processors Intel Xeon D-2700 and Intel Xeon D-1700 are designed for space- and power-constrained ruggedized environments, feature industrial-class reliability, hardware-based security, and up to 56 high-speed PCIe lanes to support networks with up to 100Gbps Ethernet. While the Intel Xeon D-1700 sub-family is scalable from 2 to 10 cores, the Intel Xeon D-2700 family goes up […]

Open-source LXI Tools is made for “LAN eXtensions for Instrumentation” compliant test instruments

LXI Tools is an open-source project designed to manage Ethernet-connected test instruments such as oscilloscopes, power supplies, spectrum analyzers, etc… that are compliant with the “LAN eXtensions for Instrumentation” standard, or LXI for shorts, hence the name of the project. LXI Tools is available either as a command-line program (lxi) or a graphical user interface (lxi-gui), and includes features such as the automatic discovery of test instruments, sending SCPI (Standard Commands for Programmable Instruments) commands, grabbing screenshots from supported instruments, benchmarking SCPI message performance, and Lua scripting for test automation. The tool is compatible with higher-end instruments compatible with LXI from vendors such as Keysight Technologies, Kikusui Electronics, Rigol Technologies, Rohde & Schwarz, Siglent Technologies, and Tektronix. All support SCPI commands, while autodiscovery and screenshot functions are supported by most tested models. While it’s possible to build the project from source using meson, the easiest way to install LXI Tools […]

Aerofara Aero 2 Pro Review – A Celeron N5105 mini PC tested with Windows 11, Ubuntu 20.04

Aerofara’s Aero 2 Pro is an Intel Jasper Lake mini PC and one of the very few new mini PCs to include a VGA port. Aerofara kindly sent one for review and I’ve looked at performance running both Windows and Ubuntu. Aero 2 Pro Hardware Overview The Aero 2 Pro physically consists of a 120 x 120 x 23mm (4.72 x 4.72 x 0.91 inches) rectangular metal case with inset front and back plastic panels. As an actively cooled mini PC, it uses Intel’s 10 nm Jasper Lake N5105 processor which is a quad-core 4-thread 2.00 GHz Celeron processor boosting to 2.90 GHz with Intel’s UHD Graphics. The front panel is bereft of anything save a pinhole which is illuminated blue when the device is powered on. The rear panel includes the power jack, a USB 3.1 port, an HDMI port, an Ethernet port, a 3.5mm headphone jack, and a […]

Fixing performance issues with Realtek RTL8156B 2.5GbE USB dongle in Ubuntu

A few days ago, I reviewed a USB 3.0 to 2.5 Gbps Ethernet adapter based on Realtek RTL8156B chip in Ubuntu 20.04, and let’s say the reliability and performance were underwhelming. I got some recommendations like changing cables, the MTU size, etc… Playing around with cables did no help, but one comment mentioned the cdc_ncm driver could be the issue, followed by another saying that updating to Linux kernel 5.14 should install the correct r8152 driver… So I just did that:

sudo apt install linux-oem-20.04d

1	sudo apt install linux-oem-20.04d

This upgraded Linux 5.13 (shipped with Ubuntu 20.04 + HWE) to Linux 5.14, but still no luck as the system kept using the cdc_ncm driver with a half-duplex link:

But then I thought I may have to use udev rules to prevent loading the cdc_ncm driver, and there’s indeed 50-usb-realtek-net.rules in r8152 driver to do just that. So I copied the file in /etc/udev/rules.d/ folder. Since I […]
