Hi Anthony,

This is an error message from the Or1ksim saying that it has no memory
at location 80000000, so it can't load your code there. Have you
configured a memory block at that location in your sim.cfg file?

HTH,

Jeremy

since I have downloaded the new tool chain from opencores web
and run the newest cross compiler in a linux machine
The previous problem have been sloved

However I add something on the xess.ld as follows
.rodata :
{
*(.rodata)
*(.rodata.str1.1)
*(.rodata.cst4)
__etext = . ;
} > ram
If not add these, the ld will give out some error information
But I don't know whether is rigth to this.
The linker can work correctly and generate the excutable file

Now, the problem is coming when I use simulator:
It will reports that:
ERR: 8-bit program load out of memory area: 80000000
...
ERR: 8-bit program load out of memory area: 80001d08
ERR: 8-bit program load out of memory area: 80001d09
ERR: 8-bit program load out of memory area: 80001d0a

ERR: 8-bit program load out of memory area: 80001d0c
ERR: 8-bit program load out of memory area: 80001d0d

when I use the decompiler to see the asm file
Disassembly of section .text:

80000000 <__start>:
80000000: 9c 61 00 00 l.addi r3,r1,0x0

80000008: 15 00 00 00 l.nop 0x0

8000000c <_report1>:

80000010: d4 01 10 00 l.sw 0x0(r1),r2
80000014: 9c 41 00 18 l.addi r2,r1,0x18
80000018: d7 e2 1f f8 l.sw 0xfffffff8(r2),r3
8000001c: 9c 60 12 34 l.addi r3,r0,0x1234
80000020: d7 e2 1f f4 l.sw 0xfffffff4(r2),r3
80000024: 84 82 ff f4 l.lwz r4,0xfffffff4(r2)
80000028: d7 e2 27 fc l.sw 0xfffffffc(r2),r4

I don't know why this is happen
So any can help
Thank you deeply
