Errors in PSIM

[Joel Sherrill]

It could be another task exiting. You mentioned loading code.

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?

Ok.

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

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.

Can you help me set these 2 things up? I'm not really sure how to deal with that memory issue and the internal error as well.

That address is invalid for psim. Where does the partition memory come from? Here I'd the memory keep for psim

I'm also getting the following error when I uncomment the function that creates 10 partitions to be used by my application:

core_find_mapping() - access to unmaped address, attach a default map to handle this - addr=0x1000d2c nr_bytes=0x4 processor=0xa8e5000 cia=0x1028c

Can you please help?

The file 'events.c' is inside /gdb-7.5.1/sim/ppc.

I am using psim-gdb testing my own application, it's not an RTEMS example.

I managed to break right on it, and it stops at:
../../../../../../rtems/c/src/../../cpukit/score/src/interr.c:58

Signature is the following:
the_source=the_source at entry=INTERNAL_ERROR_CORE, is_internal=is_internal at entry=true,
    the_error=the_error at entry=5)

I have no clue of what it can be. Do you have any idea?

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?

Hi everyone,

I was just testing my application using PSIM and it is returning the following lines, right after starting a Task:

rtems-4.10.99.0(PowerPC/Generic (classic FPU)/psim) PANIC ERROR 5
events.c:404: assertion failed - events->time_from_event > 0

Has anybody experienced this before?

Thanks.
Cassio
