The ARM9E-S forms one component of a debug system that interfaces from the
high-level debugging performed by the user to the low-level interface supported by the
ARM9E-S. Figure 7-1 shows a typical debug system.
A debug system typically has three parts:
•
•
•
The debug host and the protocol converter are system-dependent.
The debug host is a computer running a software debugger, such as armsd. The debug
host allows you to issue high-level commands such as setting breakpoints or examining
the contents of memory.
