Psim is a specific simulated hardware environment and does not as configured match any board. If you got addresses from a piece of real hardware, the addresses will not match. What target board's manual are you reading?

<div>1) The Init task is already deleting itself after loading the other tasks. Do I have to do something else?</div>

<div>2) The memory for partitions came from the board data sheet. I based myself on the addresses mentioned there and followed upon. I was creating the first one starting at 0x10000 and incrementing from that according to each partition's size.</div>

Break at the fault handler printing that.
Does this happen with any rtems provided examples?
Are you using the psim or psim-gdb script to run it?
