system freeze at first ble instruction

[makouda]

I try to build a basic ble advertising program, I'm using SDK9 and softdevice 110 hex coming with. but just by calling any ble instruction the system freeze(my led not longer blinking and blingking without any ble function all). my first procedure is to initialize ble stack, the first instruction is SOFTDEVICE_HANDLER_INIT but when the system reach this instruction it freeze

No it doesn't freeze. It goes somewhere and it's doing something. You are probably in an error handler. Hit break in a debugger and find out where you are and how you got there.
