Looks like you have the wrong debug configuration. Which debugger are you using ? You need to configure the debug for the one you are using not the general debug config.

You must first flash it using either nrjprog with JLink or IDAPnRFProg with IDAP-Link CMSIS-DAP. You only need to do this once. This is due to the fact that the DFU address must be written to the UICR register. You can also manually write UICR too. After that you can debug using Eclipse GCC until UICR got erased. Without UICR address, the softdevice would not jump to DFU, hence you cannot debug.

You need to create a debug configuration base on the jtag you are using to debug.
