Hello Aryeh,

You can also use the same approach as you did with mcuboot, just create a new file named firmware_loader.conf in the sysbuild folder and add the same configuration settings. Note: when adding new files in the sysbuild folder, you must do a pristine build for the new file to be detected by the build system.

Best regards,

Vidar

Hello Vidar,

Thank You!

If I understand right, this is a global change, in

C:\ncs\nrf-bm\v0.9.0\nrf-bm\samples\mcumgr\ble_mcumgr\prj.conf

I am looking for a portable, local project only solution.

For example, for the app I added the setting in CMakeLists.txt to redirect the pin

add_compile_definitions(BOARD_CONSOLE_UARTE_PIN_TX=43) # default 36=P1.04

before the line

find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})

and for the mcuboot I added in sysbuild/mcuboot.conf

CONFIG_LOG=n
CONFIG_LOG_BACKEND_BM_UARTE=n
CONFIG_CONSOLE=n
CONFIG_BM_UARTE_CONSOLE=n
CONFIG_UART_CONSOLE=n

and it does the job.

Now I am looking for a portable solution for the MCUmgr (firmware_loader) as well.

Is it exists?

Best Regards,

Aryeh

Hello Aryeh,

It should be sufficient to change the project configuration to disable the LOG and CONSOLE:
