How to prevent boot info being sent out over UART on initial start up

[Mike Austin (LPI)]

When I have the UART connected to Terminal, and I reboot my hardware, I get all the following information sent out:

*** Booting Zephyr OS build v3.2.99-ncs1 ***
I: Starting bootloader
I: Primary image: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=0x3
I: Secondary image: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=0x3
I: Boot source: none
I: Swap type: none
I: Bootloader chainload address offset: 0xc000

I am setting up some factory testing, where the result of the testing will get sent to my terminal software after each device has been tested, but I don't want all the above information clogging up my file.

Is there an easy way to disable this information from being printed to the UART?

Regards,

Mike

Hi

We need to turn of logging from the bootloader also. To do that do the following:

If you select 

And then in go into your project view in VScode, into the child_image folder and create a file named for example mcuboot.conf

and add the following line:

CONFIG_LOG=n

And then do a prestine build, we should not see any logs. 

You can also verify this by checking the out .config file in the output for mcuboot
