Hello,
i am currently trying to build a minimal firmware for the nRF5340 on the Thingy:91x.
Unfortunately my build failles to link zephyr/zephyr_pre0.elf:FAILED: zephyr/zephyr_pre0.elf zephyr/zephyr_pre0.map .../app/build/app/zephyr/zephyr_pre0.map

My suspicion is that the libbmm350_init_minimal.a library, that is built for the thingy board to reduce the quiescent current of the BMM350, is only build once (only one libbmm350_init_minimal.a file in the build folder) with the devicetree-handle __device_dts_ord_133 (handle for the ldo powering the sensors), but the multi-image-build actually has multiple devicetree_generated.h files for the different images which use different handles:

Does anyone know how to solve this problem?
I am building against the sdk-nrf v2.9.1.
