you need to have a copy of the program you want to debug.
gdbserve.nlm does not need your program's symbol table, so you
can strip the program if necessary to save space. gdb on the
host system does all the symbol handling.
To use the server, you must tell it how to communicate with
gdb; the name of your program; and the arguments for your
program. The syntax is:
load gdbserve [ BOARD=board ] [ PORT=port ]
[ BAUD=baud ] program [ args … ]
board and port specify the serial line; baud specifies
the baud rate used by the connection. port and node default
to 0, baud defaults to 9600bps.
For example, to debug Emacs with the argument foo.txtand
communicate with gdb over serial port number 2 or board 1
using a 19200bps connection:
load gdbserve BOARD=1 PORT=2 BAUD=19200 emacs foo.txt
