# \brief Example for debugging a service
|
|
# \author Norman Feske
|
|
# \date 2011-09-13
|
|
#
|
|
# This example shows how GDB monitor can be used to debug a Genode service.
|
|
# GDB monitor sits in between the service and the service's parent. Any
|
|
# service announcements are transparently propagated through the GDB
|
|
# monitor to the parent. This way, the internal state of a service can
|
|
# be observed at any time via a remote GDB connection. In the example,
|
|
# the remote GDB connection is realized via an UART device. Alternatively,
|
|
# 'tcp_terminal' could be used (to attach GDB via a network connection).
