What is GDB and how can I use it for embedded debugging?

GDB, or the GNU Debugger, is a powerful tool for debugging applications, including those running on embedded systems. It allows you to inspect the state of your program, control its execution, and analyze crashes.

Can you explain how to set up GDB for an embedded system?

To set up GDB for embedded debugging, you'll need to cross-compile your application for the target architecture and use a GDB server that communicates with your embedded device. You can then connect GDB to the server to start debugging.

What are some common commands I should know when using GDB?

Some common GDB commands include 'break' to set breakpoints, 'run' to start your program, 'next' to step over lines, and 'print' to display variable values.

Are there any specific challenges when debugging embedded systems?

Yes, debugging embedded systems can be challenging due to limited resources, lack of user interfaces, and the need for real-time performance. It's important to have a good understanding of the hardware and software interactions.
