Hi,

This could be because of secure region (SPM) enabling the serial drivers uart0 and uart1.

Could you try to add this to the CMakeLists.txt file (just below the cmake_minimum_required(..) line):

if (EXISTS "${CMAKE_CURRENT_SOURCE_DIR}/spm.conf")
  set(spm_CONF_FILE
    prj.conf
    ${CMAKE_CURRENT_LIST_DIR}/spm.conf
  )
endif()

if (EXISTS "${CMAKE_CURRENT_SOURCE_DIR}/mcuboot.conf")
  set(mcuboot_CONF_FILE
    prj.conf
    ${CMAKE_CURRENT_LIST_DIR}/mcuboot.conf
  )
endif()

if (EXISTS "${CMAKE_CURRENT_SOURCE_DIR}/${BOARD}.overlay")
  set(mcuboot_DTC_OVERLAY_FILE "${CMAKE_CURRENT_SOURCE_DIR}/${BOARD}.overlay")
endif()

Then you create a $(BOARD).overlay (nrf9160dk_nrf9160ns.overlay in this case) file holding:

&uart1 {
    status = "disabled";
};

/* rest of your overlay configurations here */

You can also create a file "spm.conf" where you can disable serial if you'd like:

CONFIG_SERIAL=n

You typically want this to enter idle mode with low power consumption.

Kind regards,

Håkon
