avrmon-stk200 is a port of Denis Chertykov's Linux debug monitor system for Atmel AVR microcontrollers. It is compatible with the connection scheme used in Atmels "STK200 Starter Kit", as opposed to the original version that used the "DAPA" (Alex's Direct Avr Parallel Access) scheme. In short, the monitor system allows you to do in-systems source-level debugging on AVR microcontrollers with gdb (avr-gdb).
Dynamic Probes (Dprobes) is a generic and pervasive system debugging facility that will operate under the most extreme software conditions such as debugging a deep-rooted operating system problem in a live environment. Dprobes allows the insertion of fully automated breakpoints or probepoints anywhere in the system and user space. Each probepoint has an associated set of probe instructions that are interpreted when the probe fires. These instructions allow memory and CPU registers to be examined and altered using conditional logic. When the probe command terminates, prior to returning to the probed code, a syslog record may be optionally generated.
Java Development Environment for Emacs (JDEE) is an Emacs-based integrated development environment (IDE) for developing Java applications and applets. Features include multiple code browsers, a JPDA-based debugger, method and field completion, template-based and procedure-based code generation, Java source code interpreter, context-sensitive help, and more.
Fuzz is a tool for testing software. It runs the target program repeatedly and provides random data streams to applications in a number of ways and then reports whether the program can be made to crash. It is a similar but more advanced version of the tool used to compile the original fuzz paper.
The GNU Compiler Collection contains frontends for C, C++, Objective-C, Fortran, Java, and Ada as well as libraries for these languages. It is a full-featured ANSI C compiler with support for K&R C as well. GCC provides many levels of source code error checking traditionally provided by other tools (such as lint), produces debugging information, and can perform many different optimizations to the resulting object code.
The GNU Debugger (GDB) is a source-level debugger for C, C++, Java, Modula-2, and several other languages. It runs on GNU/Linux, the BSD's, and almost every major proprietary OS. GDB can debug programs running on the same machine as itself, or it can communicate over a network or serial line with a debugging stub on another machine; thus, it can be used for embedded and kernel debugging.
