Bootloader dfu

HI, I have to implement buttonless bootloader.I am having simple doubt.I am programming softdevice,application(Hrs example with bootloader),bootloader hex file using nrfgostudio one by one in the following sequence.I am having doubt whether it should be in application or bootloader mode.But my device is in bootloader mode and advertising as DfuTarg.But i want to be in application mode.After enabling the dfu service it should go to Bootloader mode and after that i can do DFU.I am compiling the program using eclipse gcc. My sdk version 9.0.0 sd s130.

Can u explain me the second method.What does mean by Attribute.How to implement that.

Second Method

Modify the bootloader firmware to write 0x01 to that address using attribute . It's the same way as we did on writing to NRF_UICR_BOOT_START_ADDRESS the value of BOOTLOADER_REGION_START (see bootloader_setting_arm.c)
