You should include the GDB support in the application you download, in the
form of GDB stubs.

To do this, go to the "eCos HAL" package and under "Source-level debugging
support" there is the "Include GDB stubs in HAL" option (aka
CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS), which you should enable. If you want
Ctrl-C to work with stubs enabled, you should also enable GDB break support
for stubs (CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT).

Jesper may have some more input.
