Enabling MCU BOOT

NickH

Hi,

I have a project which has been working fine but since adding some date/time functionality, when I enable MCU_BOOT, I get linker errors that I can't seem to get to the bottom of.

If I set the following in prj.conf:

CONFIG_BOOTLOADER_MCUBOOT=n
I can compile and link OK.
If change to: 
CONFIG_BOOTLOADER_MCUBOOT=y
I get the following linker errors:
/opt/nordic/ncs/toolchains/580e4ef81c/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd: modules/nrf/lib/date_time/lib..__nrf__lib__date_time.a(date_time_core.c.obj): in function `k_work_delayable_is_pending':

I am running NCS v2.6.2.
Any idea what could be the issue?

    Hi,

     

    Are you including the DATE_TIME library in your mcuboot?

    You can check this by searching in the build/mcuboot/zephyr/.config file and see if it is set.

     

    To n-select this in mcuboot, you can create "child_images/mcuboot.conf" and set the config CONFIG_DATE_TIME=n.

    Remember to remove your build folder and regenerate the project when adding/removing configuration files.

     

    Could you try this and report back if you still see this issue?

     

    Kind regards,

    Håkon

    Håkon,

    I am in the process of upgrading to to NCS v2.7.0 and have migrated my board to HWMv2 but I hit the same issue as above when compiling using MCUBOOT.
    i.e. with MCUBOOT disabled via:
    CONFIG_BOOTLOADER_MCUBOOT=n
    I can compile and link ok.

    With CONFIG_BOOTLOADER_MCUBOOT=y, I get:

    /opt/nordic/ncs/toolchains/f8037e9b83/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd: modules/nrf/lib/date_time/lib..__nrf__lib__date_time.a(date_time_core.c.obj): in function `k_work_delayable_is_pending':

/opt/nordic/ncs/v2.7.0/nrf/lib/date_time/date_time_core.c:72: undefined reference to `k_work_reschedule_for_queue'
/opt/nordic/ncs/toolchains/f8037e9b83/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd: modules/nrf/lib/date_time/lib..__nrf__lib__date_time.a(date_time_core.c.obj): in function `date_time_core_init':
/opt/nordic/ncs/v2.7.0/nrf/lib/date_time/date_time_core.c:152: undefined reference to `k_work_queue_start'
collect2: error: ld returned 1 exit status

    I added CONFIG_DATE_TIME=n to the MCBOOT prj.conf but this time it makes no difference.
    Any clues as to what might be the issue?

    Oops - my bad - I set to CONFIG_DATE_TIME=y rather than CONFIG_DATE_TIME=n...

    User error:-)

    No worries!

    Thanks for updating the thread, Nick. Glad to hear that the porting to HWMv2 is going along without too many issues.

    Feel free to contact us if you run into any issues while updating or have any more questions!

     

    Cheers,

    Håkon
