A software developer describes tips and tricks for using the built-in debugging options on the ARM Cortex M microcontroller. (Paper from ARM TechCon 2010.)

This paper focuses on the various hardware debug options that are available on ARM Cortex M microcontrollers. I explain the debug options from a software developer's point of view and demonstrate them using a standard ARM family tool. I also show specific debugging cases such as determining the cause of a reset and how you can find the cause using the different debug options. The paper will provide information that's useful when choosing the right debugging hardware for a project.

The paper provides an overview of the JTAG interface which ARM Cortex M is based, discusses the various interfaces that are available, and provides some tips and tricks to make debugging for the software developer easier.
