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? 

[nRF9160]

I have done this but both mcuboot and SPM log is still enabled

[Heidi-Irene Harvey Sollie]

No, it shouldn't.

[nRF9160]

when i disabled Console drivers in both MCUBoot configuration and SPM configuration in "Configure nRF connect SDK Project" from Segger embedded studio, Log is disabled. 

But i want to disable Logs through configuration done in .conf file because it remains forever. while configuration made through project gone on project rebuild.

[MJD093]

Have you tried this?

CONFIG_SERIAL=n
CONFIG_STDOUT_CONSOLE=n
CONFIG_LOG=n
CONFIG_BOOT_BANNER=n
CONFIG_PRINTK=n

When I wanted to disable my UART0 and UART1 for power saving I had to use the above.

This allowed me to disable the UART0 peripheral (through additional code, this won't disable the peripherals, it will just stop them being used) as it was no longer being used by any other process and all printk() debug lines you place in your code will be surpressed so there shouldn't be any UART API issues.
