map indirectread Specifies an area which should be read indirect.
map illegal
Marks a specified memory region as an illegal memory
area. Memory accesses to this region are ignored.
map ram Specifies location of target RAM.
map region Specifies a memory region.
map reset
Restores the default mapping, which means all mem-
ory accesses are permitted.
ProjectFile
Specifies a file or directory which should be used by
the J-Link DLL to save the current configuration.
ReadIntoTraceCache
Reads the given memory area into the streaming trace
instruction cache.
ScriptFile Set script file path.
SelectTraceSource Selects which trace source should be used for tracing.
SetAllowFlashCache Enables/Disables flash cache usage.
SetAllowSimulation Enables/Disables instruction set simulation.
SetBatchMode Enables/Disables batch mode.
SetCFIFlash Specifies CFI flash area.
SetCheckModeAfterRead Enables/Disables CPSR check after read operations.
SetCompareMode Specifies the compare mode to be used.
SetCPUConnectIDCODE
Specifies an CPU IDCODE that is used to authenticate
the debug probe, when connecting to the CPU.
SetDbgPowerDownOnClose
Used to power-down the debug unit of the target CPU
when the debug session is closed.
SetETBIsPresent Selects if the connected device has an ETB.
SetETMIsPresent Selects if the connected device has an ETM.
SetFlashDLNoRMWThreshol
d
Specifies a threshold when writing to flash memory
does not cause a read-modify-write operation.
SetFlashDLThreshold Set minimum amount of data to be downloaded.
SetIgnoreReadMemErrors Specifies if read memory errors will be ignored.
SetIgnoreWriteMemErrors Specifies if write memory errors will be ignored.
SetMonModeDebug Enables/Disables monitor mode debugging.
TraceSampleAdjust
Allows to adjust the sampling timing on the specified
pins, inside the J-Trace firmware
SetResetPulseLen Defines the length of the RESET pulse in milliseconds.
SetResetType Selects the reset strategy.
SetRestartOnClose Specifies restart behavior on close.
SetRTTAddr Set address of the RTT buffer.
SetRTTTelnetPort Set the port used for RTT telnet.
SetRTTSearchRanges Set ranges to be searched for RTT buffer.
SetRXIDCode
Specifies an ID Code for Renesas RX devices to be
used by the J-Link DLL.
SetSkipProgOnCRCMatch
Specifies the CRC match / compare mode to be used.
Deprecated, use SetCompareMode instead.
SetSysPowerDownOnIdle
Used to power-down the target CPU, when there are
no transmissions between J-Link and target CPU, for a
specified timeframe.
SetVerifyDownload Specifies the verify option to be used.
SetWorkRAM Specifies RAM area to be used by the J-Link DLL.
ShowControlPanel Opens control panel.
SilentUpdateFW Update new firmware automatically.
SupplyPower
Activates/Deactivates power supply over pin 19 of the
JTAG connector.
