| Property | Description |
| Additional J-Link Options JLinkExecuteCommand – StringList | Specify additional J-Link options to allow enabling or disabling advanced features and fine tuning. For more information see J-Link Command Strings |
| Current Speed – IntegerRange | The JTAG/SWD clock frequency the J-Link is currently using. |
| DLL Version – String | The J-Link DLL version. |
| Enable Adaptive Clocking adaptive – Enumeration | Adaptive clocking is enabled. |
| Exclude Flash Cache Range JLinkExcludeFlashCacheRange – String | Define a memory range that should not be cached by J-Link. Per default, all areas that J-Link knows to be Flash memory, are cached. This means that it is assumed that the contents of this areas do not change during program execution. If this assumption does not hold true, typically because the target program modifies the flash content for data storage, then the affected area should be excluded from the cache. This may slightly reduce the debugging speed. Syntax: either 'start_address-end_address' or 'address,size'. For example: 0x08000000,0x1000. |
| Firmware Version – String | The J-Link firmware version. |
| Hardware Version – String | The J-Link hardware version. |
| J-Link DLL File JLinkARMDLLFileName – FileName | The file path of the libjlinkarm.so to use. |
| Log File JLinkLogFileName – FileName | The file to output the J-Link log to. |
| Max SWO Speed – IntegerRange | The maximum supported SWO speed. |
| Reset Type resetType – IntegerRange | The reset strategy to use. |
| Script File JLinkScriptFileName – FileName | The file path of the optional J-Link script file to use. |
| Serial Number – String | The serial number of the connected J-Link |
| Settings File JLinkProjectFileName – FileName | The file path of the automatically generated J-Link settings file to use. |
| Show Log Messages In Output Window showLog – Enumeration | Display the J-Link log messages to the output window. |
| Speed speed – IntegerRange | The required JTAG/SWD clock frequency in kHz (0 to auto-detect best possible). |
| Supply Power supplyPower – Enumeration | The J-Link supplies power to the target. |
| Target Voltage – String | The target reference voltage. |
| Trace Buffer Size traceBufferSize – IntegerRange | The size of the trace buffer |
| Use Built-in Flash Loader JLinkUseFlashLoader – Enumeration | The built-in debug component identify, flash loader and breakpoint support is used. |
| Use Built-in RTT support JLinkUseRTT – Enumeration | The built-in RTT handling is used |
| Use Built-in TRACE support JLinkUseSTRACE – Enumeration | The built-in trace handling is used |
| Verify Read Operations checkModeAfterRead – Enumeration | The CPU mode is checked after each read operation. |
| Property | Description |
