Bootloader crash (s110 softdevice 8.0.0)

Please tell me someone me how to start nRF51822 & softdevice8.0.0

I build a NRF51822 application in gcc & ECLIPSE. When to run the program, it crashes in the boot loader part.

Reset_Handler(gcc_startup_nef51.s) -> SystemInit(system_nrf51.c) ->Crash!

As a result of examined, stack pointer immediately after reset had been an invalid value. This value (0x7c0) shows the value on the ROM.

This value should have been set in softdevice, Will you are running how?
