Hello,

[quote user=""]I'm using VSCode as my debugger. Click on "Debug" and the system downloads "merged.hex":[/quote]

The picture you posted is actually showing that the mcuboot hex file (build/mcuboot/zephyr/zephyr.hex) is loaded, not the merged.hex file. Please ensure the build folder is selected as shown below to select the parent-image as the current active context, then click on the debug action.

It is also possible to start a debug session without loading the hex files again:

Best regards,

Vidar
