GDB and Insight for ChorusOS Systems

An application debugger enables you to see what is going on inside an application while it executes or what an application was doing at the moment it crashed. With a system debugger, it is possible to debug specific parts of an operating system. For ChorusOS operating systems, this includes the microkernel, the system drivers, the BSP, and certain supervisor actors. The GNU GDB Debugger for ChorusOS systems offers the following features:

• Easy-to-use graphical user interface.

• Debugging of multithreaded user and supervisor applications, including relocatable applications.

• Flexible thread handling, including per thread breakpoints, scheduler locking, individual thread suspension and resumption, and thread names.

• Visualization of ChorusOS operating system abstractions related to debugged applications or global to the system.

• Application debugging over Ethernet or serial line, and system debugging over serial line.

• Ability to debug almost every piece of code, including the boot process, the C_OS, the drivers and the applications.

Insight is a graphical user interface to GDB and provides access to most of GDB's capabilities. Insight is started by default when you start GDB.
