Why does my program go into SecureFault_Handler

Hi,

We are using nrf9160 and building the application with CMSE. When my program accesses dynamically requested memory (address 0x200128b0), the program automatically jumps to the SecureFault_Handler function. But 0x200128b0 is not part of the secure sram, so why is this happening?

Here are my partitions:




Here is the kheap__system_heap address in my .map file:




Can the experts help me?
