Changing J-Link Reset Strategy
Contents
How to change the reset strategy used by the J-Link depends on the used environment. The reset strategy can be either configured via a setting in the used environment (if available) or via J-Link Command Strings. Some applications such as the J-Link Commander allow to pass J-Link Command Strings directly to the J-Link DLL via a native command. If neither of the options is available, please refer to Using J-Link Command Strings#Generic.

Generic
If the used IDE / application does not provide the option to pass J-Link Command Strings to the J-Link DLL, we recommend to include them into a J-Link Script File using the J-Link Script File API function JLINK_ExecCommand("<JLinkCommandString>"). For further information how to use a J-Link Script File in your environment, please refer to: https://wiki.segger.com/Using_J-Link_Script_Files
Example Please find below the content of an example J-Link Scipt File which passes the J-Link Command String EnableEraseAllFlashBanks via the JLINK_ExecCommand(...) J-Link Script File command to the J-Link DLL.
