Instruction master address is only up counting for Nioas II simulation on ModelSim

Dear Daixiwen,

I appreciate your reply and pointing out.

I understand that reset vector must be adjusted by relationship between SOPC builder and Nios EDS automatically.

I s there any potential to break this coordination?

After my post I found some deference　in .objdump file between good case and bad case.

In good case, there is following part in the .objdump file.

00002000 is the my reset vector address.

=========

00002000 <__reset>:

* Jump to the _start entry point in the .text section if reset code

* is allowed or if optimizing for RTL simulation.

*/

# if defined(ALT_ALLOW_CODE_AT_RESET) || defined(ALT_SIM_OPTIMIZE)

/* Jump to the _start entry point in the .text section. */

movhi r1, %hi(_start)

2000: 00400034 movhi at,0

ori r1, r1, %lo(_start)

2004: 08480814 ori at,at,8224

jmp r1

2008: 0800683a jmp at

0000200c <_exit>:

...

===============

In bad case, there is not above part.

Is it any hint?

Tank you.
