WHich bootloader project are you using, \examples\dfu\secure_bootloader\pca10040_ble_debug or examples\dfu\secure_bootloader\pca10040_ble?

Are you able to debug the application after the DFU?

Best regards

Have you done any changes to the example, e.g. added any code or removed any code?

@suhaihui: I am not able to reproduce the behaviour with the test images from SDK v15.0.0. Did you create a custom application and then generated a firmware image(.zip) for an Applicaiton DFU? If so could you attach the hex file so that I can generate a f.zip file using that?
