ThreadX Module rise Mem Manage Fault exception

Licio MAPELLI 51

Hello, i need some help because my Module Manager resident application rise a memory exception while starting a Module. The weird is the exception rise only when Module is compiled with arm-none-eabi-gcc, while the same code compiled with IAR works properly. According to debugger the exception arise in file gcc__setup.s at line 4547 while running the <memory_copy__loop> procedure. Thank you in advance for any hint. User's image

Hello, i can add more details: the fault exception arise only if i link and call the ArmMathLib library compiled with gcc as static lib .a with options: "-mcpu=cortex-m33 -std=gnu11 -DSTM32 -DARM_MATH_MATRIX_CHECK -DARM_MATH_ROUNDING -DARM_MATH_LOOPUNROLL -DSTM32U585AIIx -DSTM32U5 -c -I../Inc -I"C:\AST\FedLearn\B-U585I-IOT02A_VESPUCCI_MODULAR_FW\Drivers\CMSIS\Core\Include" -I"C:\AST\FedLearn\B-U585I-IOT02A_VESPUCCI_MODULAR_FW\Drivers\CMSIS\DSP\Include" -O0 -ffunction-sections -fdata-sections -Wall -fPIC -fPIE -fPIC --specs=nano.specs -mfpu=fpv5-sp-d16 -mfloat-abi=hard -mthumb". Without linking the ArmMathLib the module execute properly. Thanks
