I am trying to reverse engineer an embedded firmware in IDA. It mirrors memory address 0x80000000-0x81FFFFF to 0xA0000000-0xA1FFFFFF. How do I setup IDA to recognise memory mirroring.

Edit->Segments->Rebase program

You could also do manual load and specify your image base.

  • Thanks, the issue is that, for example, a call to 0xA0000670 is the same as a call too 0x80000670. I need ida to recognise them as the same address. – dajolelor Apr 2 at 22:08
