Usage Fault : Illegal use of EPSR , NRFSDK 2.0.0 and BLE DFU NRF52840 DK

[gangs7192]

Describe the bug
In the latest NRF Connect SDK 2.0.0, I am trying to do add DFU over BLE to my main project. DFU went well when I create a workspace C:\ncs\v2.0.0\zephyr\samples\subsys\mgmt\mcumgr\smp_svr separately but i have to add DFU application to my main project. I added source files and conf files to my main project. The project compiled well but when I started DFU I observed this crash/error.

To Reproduce
Steps to reproduce the behavior:

1. mkdir build; cd build
2. cmake -DBOARD=board_xyz
3. make
4. See error

Expected behavior
DFU Successfull

Impact
Illegal use of the EPSR
