ARM Debugger 52 ARM specific SYStem Commands

NIDNTTRSTTORST
[ON | OFF]
Usually TRACE32 requires that the system reset line of a target
system is low active and has a pull-up on the target system.
This is how the system reset line is usually implemented on regular
ARM-based targets.
When connecting via NIDnT (e.g. a microSD card slot) to the
target system, the reset line might not include a pull-up on the
target system.
To circumvent problems, TRACE32 allows to drive the target reset
line via the TRST signal of an ARM debug cable.
Enable this option if you want to use the TRST signal of an ARM
debug cable as reset signal for a NIDnT.
Slave [ON | OFF] If several debuggers share the same debug port, all except one
must have this option active.
JTAG: Only one debugger - the “master” - is allowed to control the
signals nTRST and nSRST (nRESET). The other debugger need
to have Slave=OFF.
Default: OFF; ON if CORE=... >1 in config file (e.g. config.t32).
SWDP [ON | OFF] With this command you can change from the normal JTAG
interface to the serial wire debug mode. SWDP (Serial Wire Debug
Port) uses just two signals instead of five. It is required that the
target and the debugger hard- and software supports this
interface.
Default: OFF.
SWDPIdleHigh
[ON | OFF]
Keep SWDIO line high when idle. Only for Serialwire Debug mode.
Usually the debugger will pull the SWDIO data line low, when no
operation is in progress, so while the clock on the SWCLK line is
stopped (kept low).
You can configure the debugger to pull the SWDIO data line
high, when no operation is in progress by using
SYStem.CONFIG SWDPIDLEHIGH ON
Default: OFF.
