reset the device or hold down Button and power-cycle the device. but it does not work. when I debug the program of bootloader , i found that it is hardfault when it return of SystemInit (system_nrf51.c).
I already try this project on nRF51_SDK_9.0.0 ,and the result is same. I wonder that is there any errors on my operations???
