Hello,

Sorry for the late reply. We are a bit short staffed these days due to summer holidays in Norway.

[quote user=""]it will also stuck in bootloader for about 1minute and then jumo to app.[/quote]

It sounds like one of the dfu_enter_check() checks returns true, so that the device will enter DFU mode, and it times out after about one minute, and enters the application.

Can you please try to replicate this in the project:

SDK15\examples\dfu\secure_bootloader\pca10040_ble_debug project (it uses the same main.c file, so you only need to change the settings that you changed in the original bootloader project).

When you use this project, the bootloader's log will be printed over RTT. Can you please see what the log from the bootloader says, and paste it here?

Best regards,

Edvin
