Package: GDB pseudo device

Macro name

CYGPKG_DEVICES_GDB

Type

Boolean

Description

If the gdb source level debugger is going to be used to debug the application then on some target systems this will involve the exclusive use of some hardware, for example a serial line. Hence this device cannot be used for other purposes, for example C library standard I/O. If the gdb pseudo device is enabled then this provides a means of performing output operations encapsulated within the gdb protocol, thus allowing a single serial line or similar device to be used for both debugging and for output. Note that currently GDB does not support input operations. This package is only supported on the MN10300.
