MCUBOOT Building Zephyr Extra Modules

[edmcnicholas]

In my nrf connect sdk projects i have external custom driver modules that i use across various projects to simplify code reuse.  The issue i am having is that when I add MCUBOOT for dfu my modules get added to MCUBOOT and it increase the size of MCUBOOT and increases the number of config includes I need to add.  Is there a way to stop this.  Below is the include and all my bindings, kconfig, cmake, and code is included in this directory so that zephyr can pick it up.

list(APPEND ZEPHYR_EXTRA_MODULES
  ${CMAKE_CURRENT_SOURCE_DIR}/../ZephyrDrivers
  )

It appears something changes when you use EXTRA_ZEPHYR_MODULES rather then ZEPHYR_EXTRA_MODULES so that it does not get included in mcuboot.

Hi edmcnicholas,

What version of NCS are you working with? EXTRA_ZEPHYR_MODULES has replaced ZEPHYR_EXTRA_MODULES since Zephyr 3.4.0. It is still a little odd that ZEPHYR_EXTRA_MODULES still works and affect MCUboot.

2.6.1

OK, so the change to EXTRA_ZEPHYR_MODULES should be fully in place. I will raise this issue internally for analysis. Meanwhile, as things work correctly with EXTRA_ZEPHYR_MODULES, can I take it that you don't have any issue anymore?

[edmcnicholas]

Yes the issue is resolved but the symbol should be corrected as it is not showing an error with the other

I agree. I have raised the issue internally.
