I am sorry for the delays in this ticket. Unfortunately we have some low staffing on Devzone right now because of summer vacation time here in Norway. We will try to come back to you tomorrow with an update on this ticket.

Best regards,

Marjeris

I try to generate the usb dfu bootloader start from pca10100_s140_ble_debug project, and try to see if there is any good luck. but then the nrfutil can run success, I mean no error, and get 100%. but when I check the memory, the code is not there.

I also start a project from pca10100_s140_ble_debug project. and it can flash my application and my application can run after dfu.
