Build Error Enabling CONFIG_BOOTLOADER_MCUBOOT and CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU

[dlewis]

Hi,

I am developing firmware for a project using a custom board with the nrf52832. The project requires mcuboot and secure BT OTA. When I enable the configs 

CONFIG_BOOTLOADER_MCUBOOT=y

CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y

the project returns with build error "CMake Error at C:/nordic/myapps/workspace/nrf/lib/fprotect/CMakeLists.txt:15 (message):
No fprotect backend selected."

I am unfamiliar with what this is or would be caused by. I will include a zip folder with my custom board files and prj.conf. Thanks for your assistance!

Hi, could you explain that process or reasoning behind that solution a little further? Or point me towards the documentation that explains those details? Looking at the nrf52dk_nrf52832 board files used in the dev academy lessons doesn't show any inclusion of "ns" versions of dtsi files, neither do any of  the other tutorials on the matter I've seen.

Hi

I will continue to help with this ticket.

Which version of the SDK do you use?
