Commands to connect to a simulated target
Simulated targets use target-specific GDB connection commands. To configure a simulated target, a connect command is invoked that takes two GDB command scripts as parameters.
These scripts configure the simulator and simulated target (see
Section 1.1: Target connection overview on page 10
).The format of the connect command is:
connect arch-type sim-mode endian
Where, the suffixes are the same as in
Table 1: GDB command suffixes on page 10
, except
that the endian suffix is not optional.

UM1250 Target configuration
Table 12
lists the connect user commands defined by the GDB command script file sh4connect.cmd
for connecting to simulated targets.
Table 12.
Simulator connect commands
Command Description
connectsh4simle connectsh4psimle connectsh4simbe connectsh4psimbe
Connect to an ST40 functional simulator (little endian).
Connect to an ST40 performance simulator (little endian, cycle accurate).
Connect to an ST40 functional simulator (big endian).
Connect to an ST40 performance simulator (big endian, cycle accurate).
connectst40300simle connectst40300simbe connectst40300psimle
As above but for a simulated target with an ST40-300 core.
connectst40300psimbe
The connect commands listed in
Table 12: Simulator connect commands
take the following
arguments:
$arg0 specifies the command to configure the SuperH simulator
$arg1
$arg2 specifies the command to configure the simulated target
specifies the configuration commands for the SuperH simulator (see
Table 13
)
Table 13
lists the SuperH simulator configuration commands. Only one configuration command can be specified and must be specified as a string (that is, enclosed within double quotes).
Table 13.
Simulator configuration commands
Command Description
+DMM
delay
+SCIF
mode
Set the memory access delay (in cycles) to delay (ST40 performance simulator only). Default is 1 cycle.
Enable (mode is 1) or disable (mode is 0) a simulated serial port. The simulator displays a TCP/IP port number and waits for 30 seconds for the user to connect to the network port using, for example, Telnet.
As an example, the connect commands for the simulated STb7109E-Ref targets are listed in
Table 14
.
