This paper describes the development of a low-cost multiparameter acquisition system for volcanic monitoring that is applicable to gravimetry and geodesy, as well as to the visual monitoring of volcanic activity. The acquisition system was developed using a System on a Chip (SoC) Broadcom BCM2835 Linux operating system…

U-Boot is a notorious bootloader and Open Source project. This work had as objective adding support for the SquashFS filesystem to U-Boot and the support developed was submitted as a contribution to the project. The bootloader is responsible, in this context, for loading the kernel and the device tree blob into RAM. It…

—Embedded Linux processors are increasingly used for real-time computing tasks such as robotics and Internet of Things (IoT). These applications require robust and reproducible behavior from the host OS, commonly achieved through immutable firmware stored in read-only memory. SkiffOS addresses these requirements with a…

Embedded systems are playing an increasingly important role in control engineering. Despite their popularity, embedded systems are generally subject to resource constraints and it is therefore difficult to build complex control systems on embedded platforms. Traditionally, the design and implementation of control…

'Carlos E. Palau' 'Anfeng Liu'] Cloud-native computing principles such as virtualization and orchestration are key to transferring to the promising paradigm of edge computing. Challenges of containerization, operative models and scarce availability of established tools make a thorough review indispensable. Therefore…

'Xiapu Luo' 'Lei Wu' 'Kui Ren'] Dynamic analysis based on the full-system emulator QEMU is widely used for various purposes. However, it is challenging to run firmware images of embedded devices in QEMU, especially the process to boot the Linux kernel (we call this process rehosting the Linux kernel in this paper).…

The increasing complexity of modern embedded systems creates a fundamental conflict between the demand for sophisticated functionality and the strict constraints on resources and temporal determinism. Traditional operating system and hypervisor architectures, typically reliant on monolithic designs or rigid abstraction…

'Nurul Harzira Mohamad Nor' 'Yongsu Park'] As IoT devices are being widely used, malicious code is increasingly appearing in Linux environments. Sophisticated Linux malware employs various evasive techniques to deter analysis. The embedded trace microcell (ETM) supported by modern Arm CPUs is a suitable hardware tracer…

Embedded Operating Systems (OSs) are often developed in the C programming language. Developers justify this choice by the performance that can be achieved, the low memory footprint, and the ease of mapping hardware to software, as well as the strong adoption by industry of this programming language. The downside is…

Premise of the study: Image-based phenomics is a powerful approach to capture and quantify plant diversity. However, commercial platforms that make consistent image acquisition easy are often cost-prohibitive. To make high-throughput phenotyping methods more accessible, low-cost microcomputers and cameras can be used…

The Linux shell is arguably one of the most important computational tools across various scientific disciplines. Its high flexibility makes it the platform of choice for many file operations and smaller scripting tasks. Also, many stand-alone programs are called from the Linux shell - typically followed by multiple…
