RE: "FATAL ERROR: SecureFault" directly after flashing when calling one function? (Is it possibly caused by memory use?)

Hello,

In terms of the violation in your case in specific. I suggest to check the Program Counter (PC) address that trigger the SecureFault. You can take the program counter (PC) and use addr2line of the .elf file you built the application to find where it actually triggered the secure fault. Description on how to use addr2line is found here:
https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-2-debugging/topic/exercise-2-11/

In your case you should likely check what is happening at address 0x0001FC20.
