Dfu problem in segger

Hi

Getting problem in DFU feature while using segger embedded studio.Device gets programmed  successfully but stops working after that.

I am following the same process for keil and segger IDE. For keil it's working fine, but for segger it fails.

For DFU I am following this thread :

devzone.nordicsemi.com/.../

I am using sdk 11

Has any one tried dfu feature using segger IDE?

Are there any additional steps for DFU in segger IDE?
