A guide to compile and install a Xenomai-patched kernel

September 16, 2020

This tutorial will present how to compile and install a Xenomai-patched Linux kernel. Moreover, we will build Debian packages to ease the installation process. At the time of writing, the most recent stable version of Xenomai is 3.1 and the latest supported Linux kernel version is 4.19.89. However, these instructions should be valid for past and future versions. All the instructions have been executed on a machine running Ubuntu 20.04. Pre-requisites Install the following required packages: Download required files From…

Introduction This is a step-by-step guide to enable hardware (PL) – software (PS) Co-Simulation with QEMU and QuestaSim for a Vivado Zynq project running a Linux operating system and applications. Being able to simulate the interactions between the software running on the ARM processing system (PS) and the FPGA Programmable Logic (PL) allows for full-system simulation and can help development of drivers as well as embedded software that relies on the PL. Prequisites Linux-based operating system Vivado (this guide uses…

Vivado Vivado is one of our main tools when working with FPGAs. However when implementing for big FPGAs such as Kintex/Virtex Ultrascale devices, the processing can take forever when running with a high resource usage. The goal of this article is to show a way to tackle this problem and generate more bitstreams faster. By launching Vivado multiple times in the Cloud on instances of our choice (need 128 CPUs and 2TB of RAM, go ahead, just kidding, but this…

Questasim When doing HDL simulation Questasim is one of our main tools. However it only runs on Windows and GNU/Linux. Although we mostly use GNU/Linux machines Questasim is not compatible with all distributions. This mainly because of library version compatibility, albeit this being fixable, it is a pain to do (find out which library is the culprit and which version is needed). So creating a Docker image seems like a good solution. It provides a known fixed environment to Questasim…
