Hi, 

I can't read which address you used, but for boot you need boot data and vector table starting from 0x00000000. Flash config needs to be placed to address 0x400.

Hi, 

try to check memory if code is back on address 0x00000000. If you stop running - can you see where program ends?

From your tiny screenshot it doesn't look that debugger is disconnected. Just click on Pause button. From disassembly you can identify on which address program ends. Memory you can view in memory tab when MCU is suspended:

What about memory content on that address? It is empty (FF FF FF FF ) or is there valid code?

Okay, So, there is no valid code on address 0x00000000. Can you please share your project or s-record from your project?

Looks okay. There must be some issue with your j-link? debugger settings. Please check debug session settings and share output from debug console:
