Good morning,
currently we are on ncs SDK v2.7.0.
Because SDK v2.8.0 supports the KMU in MCUboot on the nRF54L15, I updated immediately and gave it a try.
Unfortunately, I encountered an odd behaviour when it comes to MCUboot and chain loading of the application.
The CPU resets somewhere behind ZEPHYR_BOOT_LOG_STOP() call (see bootloader/mcuboot/boot/zephyr/main.c:627).
I tried to debug this behaviour. Suprisingly, in debug mode, this does not happen.
So, I tried to go one step back and just gave the zephyr/samples/subsys/mgmt/mcumgr/smp_svr a try for the nrf54l15dk board target.
Unfortunately, this sample does not even compile without error (i.e. undefined reference to `z_impl_k_sem_take`).
Help appreciated.
Best regards,
Christian
