Which IDE/toolchain are you using? Keil, GCC, IAR or Segger Embedded Studio?

 Please do not use nRFGo Studio with the nRF52 Series, it has been deprecated for the nRF52 Series. Its been superseeded by the nRF Connect for Desktop: nRF Programmer app. 

Does you board advertise as DfuTarget after you flash the S332 and the bootloader?

Hi Jin, 

upon boot the bootloader will check if there is a valid application present by examining the bootloader settings page. If there is, then the bootloader will immediately jump to the application and run that. If there is no valid application then the bootloader will initialize the SoftDevice and start advertising as DfuTarget and wait for a BLE centra device to connect and send the application firmware over BLE. 

If you flashed SoftDevice, the bootloaderand the application and want the nRF to jump to the application, then you need to generate the bootloader settings page and flash that to the nRF device in order to tell the bootloader that there is a valid applicaiton present. Please see the Testing section of BLE Secure DFU Bootloader and the Generating and displaying bootloader settings. 

Best regards

when the system just turn on，it can enter to app，it's ok。

but I want to enter app if  needn't update， when it is in boot mode，what should I do？

 So you want the bootloader to stay in bootloader mode for a certain amount of time, even though there is a valid application?
