The debugging section was generalized for flash and debugging tools. The links were refactored accordly and all references were updated. To be consistent, the directory doc/guides/debbugging was renamed to doc/guides/flash_debug. Signed-off-by: Gerson Fernando Budke <nandojve@gmail.com>

GDB stub

Overview
|
|
********
|
|
|
|
The gdbstub feature provides an implementation of the GDB Remote
|
|
Serial Protocol (RSP) that allows you to remotely debug Zephyr
|
|
using GDB.
|
|
|
|
The protocol supports different connection types: serial, UDP/IP and
|
|
TCP/IP. Zephyr currently supports only serial device communication.
|
|
|
|
The GDB program acts as the client while Zephyr acts as the
|
|
server. When this feature is enabled, Zephyr stops its execution after
|
|
``gdb_init()`` starts gdbstub service and waits for a GDB
|
|
connection. Once a connection is established it is possible to
|
|
synchronously interact with Zephyr. Note that currently it is not
|
|
possible to asynchronously send commands to the target.
|
|
|
|
Enable this feature with the :option:`CONFIG_GDBSTUB` option.
