in my map file stack pointer address is at

__Stack_dtcm_end {Abs} 0x2001'f000 Data Gb <internal module>
__Stack_dtcm_start {Abs}
0x2002'0000 Data Gb <internal module>

when before start of debug when is see my registers of micro i am seeing stack pointer is at 0x5aa5'5aa4.

Hi @SPK_FW

According to the provided information, you are using software for S32K1 for a S32K3 device. The S32K3 devices have their RTDs. Please download the corresponding software from S32K3 Standard Software > Automotive SW - S32K3/S32M27x - Real-Time Drivers for Cortex-M.
