Open Source Summit + Embedded Linux Conference Europe 2020

Building open but yet reliable and failsafe embedded hard and software systems from concept to production is a challenging task. This presentation introduces and explains in detail the hard- and software architecture, tips and tricks used in design of PlutoSDR. A high performance, low cost Linux based Software Defined Radio, aimed as Active Learning Module for students to introduce fundamentals of SDR, Radio Frequency (RF) and Communications, or for HAM Radio enthusiasts at all levels. The audience will learn about high speed streaming sampled data systems using the IIO subsystem. How to configure and interact with a device that has only one Button, LED but a also a USB OTG port. USB gadget configfs usage, mindful mtd partitioning, flash locking, u-boot DFU recovery, LEDs class, input event handling and how Gadget/Mass storage can be used for ease of use field firmware updates. The PlutoSDR allows students to better understand not just the real world RF around them, but also embedded Linux, open source software, FPGA HDL development and is applicable for all students, at all levels, from all backgrounds.
