We’re currently integrating the FlexLLCE example provided for the S32E R52 core on GHS u-velOSity and have encountered a high-priority issue during execution:
The function Can_43_FLEXLLCE_SetControllerMode(Controller=0, Transition=CAN_CS_STARTED (1)) (see attached mainLLCE) does not return, as it gets stuck in a loop within Can_43_FLEXLLCE_Ipw_MainFunction_Mode, located in Can_43_FLEXLLCE_Ipw.c at line 1082, column 16 (refer to the attached Block_function_LLCE and CS_FLEXLLCE_example).
It appears that the selected controller never transitions to the CAN_STARTED state.
All prior initialization functions complete successfully and do not indicate any errors.
Please note that the LLCE firmware was compiled according to the provided instructions related to our (GHS) complier. However, we are not using your default startup code, we are instead using the startup.c file attached.

Hi @carmelom
The FlexLLCE example have their own startup code at C:\NXP\S32DS.3.5\S32DS\software\PlatformSDK_S32ZE\FLEXLLCE\Can_43_FLEXLLCE_TS_T31D53M9I3R0\examples\S32DS\FlexLLCE_example_routing_S32Z2XX_R52\Project_Settings\Startup_Code this route is the default path.
In the core.c file the CRAM and DRAM for FlexLLCE are initialized in the function Core_MPU_Init at the loop with the rbar and rlbar variables
There is the write_PRBAR (assembly function) initialize it.
