The debug Command
|
|
debug
|
|
|
|
The debug command initiates the Monitor's
|
|
gdb/dbx mode.
|
|
|
|
Format
|
|
|
|
The format for the debug command is:
|
|
|
|
debug [-svV] [-c args]
|
|
|
|
where:
|
|
|
|
-s does not set client stack pointer.
|
|
|
|
-v shows communication errors.
|
|
|
|
-V sets the verbose option.
|
|
|
|
-c args indicates that the argument or arguments args are to be
|
|
passed to the client program.
|
|
|
|
Functional Description
|
|
|
|
The debug command causes the Monitor to enter gdb/dbx mode. It is
|
|
intended to be used with either the GNU's gdb or MIPS' dbx source-level
|
|
debugger. The -V option selects verbose mode. In verbose mode, each of
|
|
the messages sent to and received from dbx are displayed on the
|
|
terminal screen. It is not possible to leave verbose mode without
|
|
leaving dbx mode and reentering dbx mode without the -V option. By
|
|
default, the Monitor displays in terse mode.
|
|
|
|
Examples illustrating the use of the debug command with MIPS' dbx follow.
|
|
|
|
% cat /etc/remote.pdbx Display port information on host port1.
|
|
port1:dv=/dev/tty1:br#9600:
|
|
|
|
% cat ~/.dbxinit Display setup for dbx.
|
|
set $pdbxport = "port1"
|
|
set $usesockets=0
|
|
set $manual_load = 1
|
|
|
|
PMON set hostport tty1 Specify protocol and port for target.
|
|
PMON set dlproto EtxAck
|
|
PMON set dlecho off
|
|
PMON load Prepare for download, and start.
|
|
|
|
% edown /dev/tty1 < test1.rec
|
|
% dbx -prom test1 Invoke dbx.
|
|
|
|
(dbx) stop in main Optionally set breakpoint at main.
|
|
(dbx) run Prepare for execution.
|
|
|
|
PMON debug Begin executing.
