or1k-sim getting "Killed" halfway of process

[0ena]

Hi,

I am new to OpenRISC.
I am experimenting with the or1ksim instruction set simulator.
Actually I am following this tutorial, in an attempt to just run the "hello.elf":

https://github.com/openrisc/tutorials/tree/master/or1ksim

When I am running the or1k-sim -f or1ksim.cfg hello.elf command, I get the following output and the process is killed:

Seeding random generator with value 0x10358439
Insn MMU 0KB: 1 ways, 64 sets, entry size 1 bytes

Do you have any ideas on what might be the problem here?

I am running or1ksim on Ubuntu 18.04.4 LTS.
I really need an answer on this. Thank you in advance for your help.

Kind regards,
Nassos
