Now I have generated bootloader.hex used by /DFU/bootloader. After programming bootloader.hex and s110_nrf51_8.0.0.hex,the device's name changed to DfuTarg.
But when I program my own application used by jlink,the device does not work.The advertising name is also DfuTarg,it means that the device run the bootloader program instead of application program.
Is there some registers should be set?
