SYStem.Option.DUALPORT
Implicitly use run-time memory access
All TRACE32 windows that display memory are updated while the processor is executing code (e.g.
). This setting has no effect if
is disabled.
If only selected memory windows should update their content during runtime, leave
SYStem.Option.DUALPORT OFF
and use the access class prefix
E
or the format option
%E
for the
specific windows.
SYStem.Option.EnReset
Allow the debugger to drive nRESET (nSRST)
[
window> EnReset
]
Default: ON.
If this option is disabled the debugger will never drive the nRESET (nSRST) line on the JTAG connector. This
is necessary if nRESET (nSRST) is no open collector or tristate signal.
From the view of the core, it is not necessary that nRESET (nSRST) becomes active at the start of a debug
session (
), but there may be other logic on the target which requires a reset.
SYStem.LOCK
Tristate the JTAG port
Default: OFF.
If the system is locked, no access to the JTAG port will be performed by the debugger. While locked, the
JTAG connector of the debugger is tristated. The intention of the
SYStem.LOCK
command is, for example,
to give JTAG access to another tool. The process can also be automated, see
It must be ensured that the state of the core JTAG state machine remains unchanged while the system is
locked. To ensure correct hand-over, the options
and
must be set properly. They define the TAP state and TCK level which is selected when the
debugger switches to tristate mode. Please note: nTRST must have a pull-up resistor on the target,
EDBGRQ must have a pull-down resistor.
