have you changed IRAM and IROM settings? check this post

Did you also check the compatibility matrix to see if your hardware revision supports SD 8.0.0?

I download the softdevice(s110_nrf51_8.0.0_softdevice.hex) on nordic web,i start the debugger and put the breakpoint in the first line of main and run,the breakpoint hits.when i start debug,the PC doesn't stop in the first line of the main.c(the PC value is 0x000006D0), and click reset button it also stop here,but the 7.0.0(softdevice and project) start debug,the PC pointer stop in the first line of the main.c(the PC value is 0x00016A80).
