What is debugging used for?

Debugging is the process of analyzing how your program runs, how it generates data in order to find defects and issues in your code. These errors or defects are referred to as “bugs”, hence the term “debugging.”

What is an onboard debugger?

The onboard debugger provides a very low level method of debugging software. Usually supplied as a set of EPROMs which are plugged into the board or as a set of software routines that are combined with the applications code, they use a serial connection to communicate with a PC or workstation.

What happens when you debug?

Running an app within a debugger, also called debugging mode, means that the debugger actively monitors everything that’s happening as the program runs. It also allows you to pause the app at any point to examine its state, and to then step through your code line by line to watch every detail as it happens.

What is OpenOCD used for?

The Open On-Chip Debugger (OpenOCD) aims to provide debugging, in-system programming and boundary-scan testing for embedded target devices. It does so with the assistance of a debug adapter, which is a small hardware module which helps provide the right kind of electrical signaling to the target being debugged.

Is debugging safe?

When you plug the Android device into a new PC, it will prompt you to approve a USB debugging connection. If you deny access, the connection is never opened. It’s a great failsafe, but users who may not know what it is may just approve the connection all willy-nilly, which is a bad thing.

Why do I need debugger?

The main use of a debugger is to run the target program under controlled conditions that permit the programmer to track its operations in progress and monitor changes in computer resources (most often memory areas used by the target program or the computer’s operating system) that may indicate malfunctioning code.

What is the advantage of having an onboard debugger?

Explanation: The onboard debugger provides a very low-level method of simulating or debugging the software. It usually handles EPROMs which are plugged into the board or a set of application codes by providing a serial connection to communicate with the PC or workstation.

What is an example of debugging?

In software development, the debugging process begins when a developer locates a code error in a computer program and is able to reproduce it. For example, an engineer might run a JTAG connection test to debug connections on an integrated circuit.

How do I use debugging?

Set a breakpoint and start the debugger

1. To debug, you need to start your app with the debugger attached to the app process.
2. Press F5 (Debug > Start Debugging) or the Start Debugging button.
3. To start your app with the debugger attached, press F11 (Debug > Step Into).

What is OpenOCD and GDB?

OpenOCD complies with the remote gdbserver protocol and, as such, can be used to debug remote targets. Setting up GDB to work with OpenOCD can involve several components: The OpenOCD server support for GDB may need to be configured. See GDB Configuration.

What is JTAG and why is it used?

JTAG (named after the Joint Test Action Group which codified it) is an industry standard for verifying designs and testing printed circuit boards after manufacture. The Joint Test Action Group formed in 1985 to develop a method of verifying designs and testing printed circuit boards after manufacture.
