Strange ARCH_HAS_STACK_PROTECTION behavior

YurBurGer

I'm developing custom board based on nrf52833. After creating new board via nRF connect extension I tried to enable FOTA. And got next warning.

warning: HW_STACK_PROTECTION (defined at arch/Kconfig:258) was assigned the value 'y' but got the
value 'n'. Check these unsatisfied dependencies: ARCH_HAS_STACK_PROTECTION (=n). See
http://docs.zephyrproject.org/latest/kconfig.html#CONFIG_HW_STACK_PROTECTION and/or look up
HW_STACK_PROTECTION in the menuconfig/guiconfig interface. The Application Development Primer,
Setting Configuration Values, and Kconfig - Tips and Best Practices sections of the manual might be
helpful too.

But if I try to enable HW_STACK_PROTECTION via Kconfig gui it says "Direct Dependencies: (=y)".

This is not happening if I select nRF52833 kit as project board. What should I do to resolve this? What is the difference between custom board and development kit in means of dependencies?

Result prj.conf just in case

CONFIG_SECURE_BOOT=y
CONFIG_BOOTLOADER_MCUBOOT=y
CONFIG_IS_BOOTLOADER=y
CONFIG_BUILD_S1_VARIANT=y
CONFIG_USERSPACE=y
CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y
CONFIG_BT_PERIPHERAL=y
CONFIG_BT=y

And build log. I realize that there also bunch of other warning, but at least I can somewhat understand how to resolve them.

    Hi,

    In this case, I think the warning for UART_NRFX  and UART_CONSOLE causes the build error if you use the default custom board files which don't include UART. You can compare the board files of the custom board and nRF52833DK.  

    warning: UART_NRFX (defined at drivers/serial/Kconfig.nrfx:6) has direct dependencies (DT_HAS_NORDIC_NRF_UART_ENABLED || DT_HAS_NORDIC_NRF_UARTE_ENABLED) && SERIAL with value n, but is currently being y-selected by the following symbols:
 - SECURE_BOOT_DEBUG_UART (defined at /home/yura/ncs/v2.4.2/nrf/subsys/bootloader/Kconfig:222), with value y, direct dependencies <choice SECURE_BOOT_DEBUG_BACKEND> (value: y), and select condition <choice SECURE_BOOT_DEBUG_BACKEND> (value: y)

warning: UART_CONSOLE (defined at drivers/console/Kconfig:43) has direct dependencies SERIAL && SERIAL_HAS_DRIVER && CONSOLE with value n, but is currently being y-selected by the following symbols:
 - SECURE_BOOT_DEBUG_UART (defined at /home/yura/ncs/v2.4.2/nrf/subsys/bootloader/Kconfig:222), with value y, direct dependencies <choice SECURE_BOOT_DEBUG_BACKEND> (value: y), and select condition <choice SECURE_BOOT_DEBUG_BACKEND> (value: y)

    Even using nRF52833DK to build with your configs, it would get the HW_STACK_PROTECTION warning. However, it would not cause the build to fail.
