Hi there
My costumer was not able to update the cpunet on a nRF5340.
A lot of troubleshooting now led to the insight, that the costumer used only the app_update.bin file and not the complete .zip folder.
Is there a way to forbid the update on the nRF5340 when the net_core_app_update.bin is missing (so when the app is not using the .zip-folder)?
SDK: v2.6.1
Thank you and best regards
Chris
Hi Chris,
One way to solve this is to always use the same verion for compatible network and application core images, and build with CONFIG_NRF53_ENFORCE_IMAGE_VERSION_EQUALITY=y.
Is it correct, that CONFIG_NRF53_ENFORCE_IMAGE_VERSION_EQUALITY=y is set in the main prj.conf and not in child_image/mcuboot/prj.conf ?
Hi,
Sorry, I should have specirfied that. The config applies to MCUboot, so you can put it in child_image/mcuboot/prj.conf.
Hi Einar
Thank you for your response.
When I put CONFIG_NRF53_ENFORCE_IMAGE_VERSION_EQUALITY=y in child_image/mcuboot/prj.conf, it says that CONFIG_NRF53_UPGRADE_NETWORK_CORE=y is missing:
But when I put CONFIG_NRF53_UPGRADE_NETWORK_CORE=y also in child_image/mcuboot/prj.conf, it says that further depedencies are missing:
If I look into the build/mcuboot/zepyhr/.config:
And here https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-8-bootloaders-and-dfu-fota/topic/exercise-3-fota-over-bluetooth-low-energy/ in Step 6.4 it says that CONFIG_NRF53_UPGRADE_NETWORK_CORE=y goes into the main prj.conf
Can you help?
Hi,
I have not been able to reproduce this on my end. However, I see it if I add CONFIG_NRF53_ENFORCE_IMAGE_VERSION_EQUALITY=y to the application configuration, where is should not be used. Can you make sure you only set CONFIG_NRF53_ENFORCE_IMAGE_VERSION_EQUALITY=y in the configuration for MCUboot?
I have set CONFIG_NRF53_ENFORCE_IMAGE_VERSION_EQUALITY=y in child_image/mcuboot/prj.conf.
In the main prj.conf it is not set.
The compiler gives the warning
warning: NRF53_ENFORCE_IMAGE_VERSION_EQUALITY (defined at
C:/_dev/_lib/ncs_2_6_1/nrf\subsys\bootloader/Kconfig:257) was assigned the value 'y' but got the
value 'n'. Check these unsatisfied dependencies: NRF53_UPGRADE_NETWORK_CORE (=n). See
http://docs.zephyrproject.org/latest/kconfig.html#CONFIG_NRF53_ENFORCE_IMAGE_VERSION_EQUALITY and/or
look up NRF53_ENFORCE_IMAGE_VERSION_EQUALITY 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.
And the update still works with only the app_update.bin file (also with an old one)
These are the .conf files

Hi,
I did not get a chance to test on my end today, but I will do so and get back to you. This feature is not much used, but in principle it should work. Note that you need CONFIG_NRF53_UPGRADE_NETWORK_CORE=y there. Another example of that can be found here (though this is also without CONFIG_NRF53_ENFORCE_IMAGE_VERSION_EQUALITY=y).
Hi,
I was incorrect about my previous statement about placing CONFIG_NRF53_ENFORCE_IMAGE_VERSION_EQUALITY=y in the mcuboot configuration. You can place it in the application configuration, and it will propagate to MCUboot. However, you also need to set CONFIG_MCUBOOT_IMGTOOL_SIGN_VERSION="1.2.3" in the application configuration.
