Hi,
I switched from NCS v2.3.0 to NCS v2.4.0. My code was building correctly with mcuboot and flash disk with NCS v2.3.0, but now I am getting the following error with newer SDK:

cc1.exe: some warnings being treated as errors
For generate the above error, please add below configuration in smp_svr sample:
#USB related configs CONFIG_USB_DEVICE_STACK=y CONFIG_USB_DEVICE_PRODUCT="Zephyr MSC sample" CONFIG_LOG=y CONFIG_USB_DRIVER_LOG_LEVEL_ERR=y CONFIG_USB_MASS_STORAGE=y CONFIG_USB_DEVICE_LOG_LEVEL_ERR=y CONFIG_USB_MASS_STORAGE_LOG_LEVEL_ERR=y CONFIG_APP_MSC_STORAGE_FLASH_LITTLEFS=y
Please help to solve this build issue with ncsv2.4.0.
