Hi all, after years of working only with pc programming I restart with avr projects.
I run a very little c program with gdb/ddd and run into the following trouble: ddd window shows c listing correct. Step works fine. If I open assembly window in ddd I get the correct output: Dump of assembler code for function __vectors: => 0x00000000 <+0>: rjmp .+24 ; 0x1a <__trampolines_start> 0x00000002 <+2>: rjmp .+78 ; 0x52 <__bad_interrupt> 0x00000004 <+4>: rjmp .+76 ; 0x52 <__bad_interrupt> 0x00000006 <+6>: rjmp .+74 ; 0x52 <__bad_interrupt> 0x00000008 <+8>: rjmp .+72 ; 0x52 <__bad_interrupt> 0x0000000a <+10>: rjmp .+70 ; 0x52 <__bad_interrupt> if I now do a "stepi": (gdb) stepi 0x0000001a in __trampolines_start () The assembler output now has an offset of 0x800000 ????? Why? Dump of assembler code from 0x80001a to 0x80011a: 0x0080001a: nop 0x0080001c: nop 0x0080001e: nop 0x00800020: nop If I set display/i $pc: (gdb) display/i $pc (gdb) stepi 0x0000001c in __trampolines_start () 1: x/i $pc => 0x1c <__trampolines_start+2>: out 0x3f, r1 ; 63 (gdb) stepi 0x0000001e in __trampolines_start () 1: x/i $pc => 0x1e <__trampolines_start+4>: ldi r28, 0x5F ; 95 (gdb) looks fine. But the assembler window has still the offset to 0x800000. Any ideas?
