Hello,
After creating a new project based on the FreeRTOS_Queues_ThreadFlags_TrustZone example from MX and generating code, there is a compile error:
[build] C:/Users/tuoma/AppData/Local/stm32cube/bundles/gnu-tools-for-stm32/13.3.1+st.9/bin/../lib/gcc/arm-none-eabi/13.3.1/../../../../arm-none-eabi/bin/ld.exe: CMakeFiles/FreeRTOS_Queues_ThreadFlags_TrustZone_AppliNonSecure.dir/Src/stm32n6xx_hal_timebase_tim.c.obj: in function `HAL_InitTick':

The function HAL_RCCEx_GetTIMGFreq is not found from the stm32n6xx_hal_rxx_ex.c where it should be based on another project.
After adding HAL_RCCEx_GetTIMGFreq to stm32n6xx_hal_rxx_ex.c and LL_RCC_CALC_TIMG_FREQ to stm32n6xx_ll_rcc.h, the code compiles.
After adding the above mentioned functions to get the code to build, it hard faults when running and debugging:

main@0x3418e9d8 (c:\Users\tuoma\STM32Cube\Example\FreeRTOS_Queues_ThreadFlags_TrustZone\FSBL\Src\main.c:92)
Is there a working example project for the STM32N6 with FSBL, AppliSecure and AppliNonSecure used?
