Hi! 

To disable MCUBoot just set this config negative

CONFIG_BOOTLOADER_MCUBOOT=n.

To disable the output from the SPM, you could set

CONFIG_SERIAL=n.

Best regards,

Heidi

[nRF9160]

When i set CONFIG_SERIAL=n, undefined reference to UART APIs error received.

I am using UART0 in my application.

In Short, I want to disable Logs on UART0 mentioned Below:

Hi!

Add this to your CMakeLists.txt file:

set(spm_CONF_FILE
    prj.conf
    $(CMAKE_CURRENT_LIST_DIR)/spm.conf
    )

and create a file called spm.conf in the same location as prj.conf that holds 

CONFIG_SERIAL=n

[nRF9160]

will it disable MCUBoot Bootloader Logs printed on UART as well?
