    Hi,

    I would recommend porting the pca10040_uart under nRF5_SDK\examples\dfu\secure_bootloader example instead of the nRF52805, since the nRF52833 like  nRF52832. 

    For boot loader parameter Settings:

    For application, you also can refer to the project under nRF5_SDK\examples\ble_peripheral\ble_app_uart\pca10100\s140

    Regards,
