Hey, you need to add this flag in conf, then the NCS boot banner will not be displayed:

CONFIG_NCS_BOOT_BANNER=n

Best regards,

Hi,

I have tested on nRF52840-dk v2.0.2. Have you also tried on nrf52840-dk?

Best regards,

Hello, thank you for the response.

I tried to add:

CONFIG_LOG=y
CONFIG_LOG_MODE_IMMEDIATE=y

but I keep seeing the booting banner.

Can I send you my project? I don't know what else I could do to resolve it.

Hi,

I have tested how to remove booting banner using central_smp_client sample in both NCS v2.2.0 and v2.4.0. In both cases, Zephyr banner message was successfully removed from the log. Main configuration option to be used in this case is CONFIG_BOOT_BANNER=n which was already present in your configuration. Starting from provided central_smp_client sample, I changed default prj.conf file from the sample and included your changes. Modifications of your prj.conf are shown below.
in NCS v2.2.0

# added to Config logger section
CONFIG_LOG=y
CONFIG_LOG_MODE_IMMEDIATE=y

in NCS v2.4.0

# added to Config logger
CONFIG_LOG=y
CONFIG_LOG_MODE_IMMEDIATE=y

# changes to mcumgr
#CONFIG_MCUMGR_SMP_UART=y
#CONFIG_MCUMGR_CMD_IMG_MGMT=y
CONFIG_IMG_MANAGER=y
CONFIG_MCUMGR_GRP_IMG=y

With these changes, you should have Zephyr banner message removed from the log.

Best regards,
Dejan
