Hello everybody,

I have a problem when I want to simulate Tremor , take a look:

I guess there's not enough memory space to fill Tremor in OR1200
architecture but I don't manage to modify sim.cfg to get a good
simulation. I've always got these very long exceptions.

If someone can help me, thanks in advance

i don't know how you configured the simulator, but if you have a default
config, there is no memory section at 0x01000074...

so you may change the sim.cfg (though you'll still need some code at
0x100, that's the entry for or32). but i guess you need to
change paddr (physical address) in the elf file header.

the code is loaded to paddr address of section so you may also
change the default linker script with one to put sections at right
addresses. (please take a look at orpmon, or
linux/arc/or32/vmlinux.lds for some examples.)
