Selecting a target involves choosing a target for debugging and setting connection
|
| 29 |
|
|
interface options for the target.
|
| 30 |
|
|
|
| 31 |
|
|
<P>Common targets include: "exec" for native debuggers, "remote" for establishing
|
| 32 |
|
|
a connection to a target board via a serial line, "remotetcp" for TCP connections,
|
| 33 |
|
|
and "sim" for connections to the simulator. There may be more depending on the
|
| 34 |
|
|
configuration of the debugger being used.</P>
|
| 35 |
|
|
|
| 36 |
|
|
<P>In general, "remote" targets are always serial connections which require the user
|
| 37 |
|
|
to specify the serial port and baud rate to be used for the connection and
|
| 38 |
|
|
"remotetcp" targets are always TCP connections which require specifying the hostname
|
| 39 |
|
|
and port number of the machine to which to connect. Depending upon configuration,
|
| 40 |
|
|
there may be numerous serial- and TCP-based connections. These always follow the
|
| 41 |
|
|
naming convention <I>target</I> and <I>target</I>tcp.</P>
|
| 42 |
|
|
|
| 43 |
|
|
<P>To <A NAME="select_tar"> select a target</A>, choose one of the available targets
|
| 44 |
|
|
from the dropdown menu in the Connection Frame. Then <A NAME="#select_int">specify
|
| 45 |
|
|
the interface options</A> for this target: selecting the baudrate and serial port
|
| 46 |
|
|
from the dropdown menus (serial targets only) or entering the hostname and port number
|
| 47 |
|
|
(TCP targets only).</P>

Three run options which may be selected include:
|
| 51 |
|
|
<DL>
|
| 52 |
|
|
<DT><A NAME="options_run_until_main">Run until 'main'
|
| 53 |
|
|
<DD>Sets a breakpoint at main(). This has no effect when using
|
| 54 |
|
|
GDB in tracing mode.
|
| 55 |
|
|
<DT><A NAME="options_bp_at_exit">Set breakpoint at 'exit'
|
| 56 |
|
|
<DD>Sets a breakpoint at exit(). This has no effect when using
|
| 57 |
|
|
GDB in tracing mode.
|
| 58 |
|
|
<DT><A NAME="options_download_dialog">Display Download Dialog
|
| 59 |
|
|
<DD>Displays a dialog showing the progress of the download to
|
| 60 |
|
|
the target section by section. This has no effect when using
|
| 61 |
|
|
GDB in tracing mode.
|
| 62 |
|
|
<DT><A NAME="options_compare_to_remote_executable">
|
| 63 |
|
|
Compare to remote executable</A>
|
| 64 |
|
|
<DD>When attaching to a tracing target, compare the host's and target's
|
| 65 |
|
|
executable by computing the checksum of each loadable section.
