After I inserted JLINK_MONITOR.c, JLINK_MONITOR.h and SES_NRF52_STARTUP.s in my project.  I also followed all instructions but I am keep getting the following errors:

Output/SES_3e Release/Obj/JLINK_MONITOR_ISR_SES.o: in function `DebugMon_Handler':

undefined reference to `JLINK_MONITOR_OnEnter'

Output/SES_3e Release/Obj/JLINK_MONITOR_ISR_SES.o: in function `_WaitForJLinkCmd':

undefined reference to `JLINK_MONITOR_OnPoll'

Output/SES_3e Release/Obj/JLINK_MONITOR_ISR_SES.o: in function `_HandleRestartCPU':

undefined reference to `JLINK_MONITOR_OnExit'

I edited my J-Link additional options in SES with "SetMonModeDebug = 1;SetMonModeVTableAddr = 0x26000" from project in Common configuration

Can you please help with this issue? Do I have to run J-Link script and where do I get it from for my specific device 52840?

It seems like you're not compiling JLINK_MONITOR.c as the linker can't find the references to the functions it contains.

What SDK you using? 

Are you using the SoftDevice? 

[DivyeshP]

yes SoftDevice

Have you included JLINK_MONITOR.h in main.c?

What SDK are you using?
