Cannot unset breakpoint at main (using segger with nrf52840dk)

[bermanmk]

Using segger nordic edition I cannot unset the breakpoint for the first instruction in the main() function. Since I'm using zephyr with wireless on this board it causes a crash every time I load debug since the main thread executes concurrently with wireless service calls. Is there a way to unset this breakpoint?

It doesn't actually show up as a breakpoint in segger when programming/debugging, but the j-link commander shows a hardware breakpoint being set to the address of the first instruction in the main() function. I cannot figure out where in the build/debug process this breakpoint is being set, but it happens somewhere in the upload/veriify stage because there are no hardware breakpoints set prior to the board starting.

It's driving me crazy because every time I build and debug I then have to manually reset the board to get it to ignore that breakpoint.

Hello,

Please try to change debugger settings as shown in the screenshot below. This should disable the automatic breakpoint on startup.

Gotcha. It seems that the "Configure NRF Connect Project" option overwrites this value. Is there a way to override that behavior?

I'm afraid there is no easy way to change the default project settings as the projects are auto generated when you import a NCS example into SES.  Maybe if you modify the \ncs\v1.4.2\toolchain\segger_embedded_studio\html\create_nordic_project.py.py script. The debugger configuration appear to be defined at line ~408:

    if start != -1 and end != -1:
        inputs = out[start + 14:end].strip().split("\n")
        xml.append('  <project Name="zephyr/merged.hex">')
        line = ('    <configuration Name="Common"'
                ' debug_initial_breakpoint="z_cstart"'
                ' debug_start_from_entry_point_symbol="No"'
                ' project_dependencies="all(build)"'
                ' external_build_file_name="$(ProjectDir)/zephyr/merged.hex"')
