MCUBOOT LOGS

HI,

Am using west tool to build and flash .and am following this link. https://docs.zephyrproject.org/3.0.0/guides/west/sign.html . they mentioned in that link after the cmd west flash -d build-hello-signed , it supposed to give the mcuboot logs as well as application prints. But after doing that i didn't get the mcuboot logs but am able to see the print msg from application . I need to see the mcuboot logs once application is running. Kindy help me what am i missing here. ( note - am using windows environment )

Hi Shikamaru,

I don't see the relation between west flash -d build-hello-signed and the log from MCUBoot.

What make build-hello-signed different is the -DCONFIG_MCUBOOT_SIGNATURE_KEY_FILE which mean a custom signature key is provided and will be used to sign the image. It has nothing to do with logging in MCUBoot.

Which log do you have when you boot ?
Have you configured (if you plan to send log to UART):

CONFIG_LOG=y

CONFIG_LOG_BACKEND_UART=y

In the prj.conf for MCUBoot project or in the overlay mcuboot.conf if you are in your application project.

If you do the overlay you should put it in something like this:

mcuboot.conf file , inside child_image folder inside your project.
