target type parameters
Further parameters are interpreted by the target protocol, but typically include things like device names or host names to connect with, process numbers, and baud rates.
The target command does not repeat if you press <RET> again
after executing the command.
help target
info target or info files
(see Commands to specify files).
help target name
set gnutarget args
set gnutarget command. Unlike most target commands,
with gnutarget the target refers to a program, not a machine.
Warning: To specify a file format with set gnutarget,
you must know the actual BFD name.
show gnutarget
show gnutarget command to display what file format
gnutarget is set to read. If you have not set gnutarget,
GDB will determine the file format for each file automatically,
and show gnutarget displays The current BDF target is "auto".
Here are some common targets (available, or not, depending on the GDB configuration):
target exec program
target exec program is the same as
exec-file program.
target core filename
target core filename is the same as
core-file filename.
target remote dev
/dev/ttya). See Remote debugging. target remote
supports the load command. This is only useful if you have
some other way of getting the stub to the target system, and you can put
it somewhere in memory where it won't get clobbered by the download.
target sim
target sim
load
run
works; however, you cannot assume that a specific memory map, device drivers, or even basic I/O is available, although some simulators do provide these. For info about any processor-specific simulator details, see the appropriate section in Embedded Processors.
Some configurations may include these targets as well:
target nrom dev
Different targets are available on different configurations of GDB; your configuration may have more or fewer targets.
Many remote targets require you to download the executable's code once you've successfully established a connection.
load filename
load command may be available. Where it exists, it
is meant to make filename (an executable) available for debugging
on the remote system--by downloading, or dynamic linking, for example.
load also records the filename symbol table in GDB, like
the add-symbol-file command.
If your GDB does not have a load command, attempting to
execute it gets the error message "You can't do that when your
target is ..."
The file is loaded at whatever address is specified in the executable. For some object file formats, you can specify the load address when you link the program; for other formats, like a.out, the object file format specifies a fixed address.
load does not repeat if you press <RET> again after using it.
