The OMAP. Code Composer Studio. (CCStudio) Integrated Development Environment
(IDE) provides debug support for the OMAP platform via heterogeneous debugging of the
TMS470. ARM and TMS320C5000.-based DSP subsystem cores, which are connected
on the same JTAG scan path within the device. Simultaneous debug of two or more CPUs,
sometimes referred to as co-emulation, allows the user to coordinate debugging between
both of the processors. The Parallel Debug Manager (PDM) control within Code Composer
Studio IDE can be used to execute the targets in parallel, i.e., stepping or running. It can also
be used to configure global breakpoints. This feature allows you to designate both processors
to halt when either processor halts. Global breakpoints and co-emulation are very useful
when trying to debug code that provides communication or signaling between processors.
This application report describes how to setup Code Composer Studio using the
heterogeneous device driver, and how to start debugging an OMAP platform using the
Parallel Debug Manager. Although some of the values will be different for other OMAP
platforms, the process contained in this application report can be used as a framework for
those devices.
