Linux-on-Jetson SDR board gets major software upgrade

Deepwave Digital’s v0.2 release of the Ubuntu-based AirStack software for its Nvidia TX2 and Artix-7 equipped AIR-T SDR dev board adds variable sample rate, phase locking for MIMO, easier updates, and support for Jetpack 4.2.2, Docker, and the Jetson TX2i. Philadelphia-based Deepwave Digital has released version 0.2.0 of the Ubuntu-driven stack that drives its Jetson TX2-enabled AIR-T (Artificial Intelligence Radio — Transceiver) board for software defined radio (SDR). AirStack 0.2.0 offers improved hardware support, easier upgrades, and new features like variable sample rate support. The release takes a step toward the company’s eventual goal of turning AIR-T into a field-deployable system, says Deepwave Digital.

Pi for Everyone and Everything

Pi foundation released their first system-on-a-chip (SOC) in 2012, they had no idea how overwhelming the response would be. The credit-card-sized computer once meant to be an easy entry point for British students to get into programming and computer science has burgeoned into a whole community of add-on boards (“hats”), screens and extras that people all around the world are using for all kinds of things. Raspberry Pi computers have ARM processors on them and most Linux distributions that support those processors will run on them. There are also Windows 10 IOT (Internet of Things) embedded platforms that will run on them as well. The most popular operating system for it by far is Raspbian, which is a derivative of Debian Linux. The Raspberry Pi foundation also has an OS image called NOOBS, which will allow you to install a number of different options on it as well. Getting started is as easy as buying a Pi, a case and its accompanying necessities, which you might already own, namely a microSD card, a 5V-2A wall-wart-type supply with a micro USB connection, an HDMI cable and a USB keyboard and mouse. Several starter kits are available that include cases, power supplies and NOOBS already installed on a microSD card. If you already have access to a microSD card, it is simple enough to go to www.raspberrypi.org and download any of the OS images that they have there. There are also details on how to get the image onto the card.
