catnip is a tiny network packet mirroring tool. The server (source) is not based on libpcap and, when compiled and stripped, makes the binary smaller than 20kiB. This makes it very suitable for embedded environments where a libpcap-based tool, typically 100kiB for just libpcap and 500kiB for tcpdump, would be simply too large. What makes catnip stand out from other small packet capturing tools is that it presents the remote systems interface as a local TUN/TAP interface, but additionally can apply a BPF filter at the remote end to send to you only the traffic you are interested in.
OpenBricks is an enterprise-grade embedded Linux framework that provides easy creation of custom distributions for industrial embedded devices. It features a complete embedded development kit for rapid deployment on x86, ARM, PowerPC, and MIPS systems with support for industry leaders. It is meant for individuals and companies that are looking for rapid board bring-up with fine-grain embedded Linux distribution setup with complete customization. It eliminates the need to care about BSP and toolchain.
Coretrace is a lightweight tool for debugging embedded Linux applications. It works by analyzing core files from crashed applications and outputs a short plain-text backtrace, suitable for putting into logfiles. The basic idea is to let the failing unit do self analysis of core files and report those back home during device maintenance lifetime. Non-interactive small-sized embedded systems are the primary targets, so small footprint is of major concern, since it will be stored on flash. Currently the compiled size is approximately 20 kb.
NETSHe is a feature-rich and general-purpose Web interface and initialization system for OpenWRT-based firmware. Its main features are network interface management (including point-to-point and wireless), VLANs and aliases, advanced routing (static, multipath, rule-based, RIP, OSPF, BGP), a zone-based firewall, bridges with brouter and filtering capability, interface bonding, quality of service, bandwidth management, traffic shaping, rate control, traffic prioritization, L7 based IP traffic filtering and marking, extended management of wireless interfaces, an access concentrator for variable VPNs (PPTP, L2TP, and OpenVPN), and much more.
QM is a graphical UML modeling tool for designing and implementing real-time embedded applications based on the QP state machine frameworks from Quantum Leaps. QM provides a graphical UML state machine diagram editor and generates production-quality, portable, and human-readable C or C++ code that is fully traceable from the design.
Paparazzi is powerful and versatile autopilot system for fixed-wing aircraft and multicopters. It comprises both hardware and software. The project includes not only the airborne hardware and software, from voltage regulators and GPS receivers to Kalman filtering code, but also a powerful and ever-expanding array of ground hardware and software including modems, antennas, and a highly evolved user-friendly ground control software interface.
musl is a new implementation of the standard library for Linux-based systems. It is lightweight, fast, simple, free, and strives to be correct in the sense of standards-conformance and safety. It includes a wrapper for building programs against musl in place of the system standard library (e.g. glibc), making it possible to immediately evaluate the library and build compact statically linked binaries with it.
The yaSSL Embedded Web Server is a fast, embeddable, and easy-to-configure Web server with a strong focus on portability and security. The Web server offers SSL/TLS (HTTPS) support built-in through the CyaSSL embedded SSL Library. With a footprint size of less than 100kB with SSL enabled (or 40kB without SSL) and a simple and clean API, the yaSSL Embedded Web Server was designed to fit perfectly into resource-constrained embedded environments. While maintaining a small size and fast speeds, the yaSSL Embedded Web Server offers a full feature set to give you the maximum amount of freedom and flexibility when developing your project.
