Hi, I don’t know if this is the correct mailing list. I’m looking for help with avr-gdb.
I'm not sure if this is a dumb question! I'm debugging a firmware image I wrote, connecting to simulator via target remote. When I do disassemble 0, I get the correct assembly for address 0x0000 on my image (it's an AVR program by the way). But, gdb seems to think it's in some random function that has nothing to do with the startup code… (gdb) disassemble 0x0000 Dump of assembler code for function _ZN5swift9RefCountsINS_21SideTableRefCountBitsEE11doDecrementILNS_13PerformDeinitE0EEEbm: 0x00000000 <+0>: jmp 0x90 ; 0x90 <__init> … (this is the start of program memory at 0x0000 on the AVR chip, the reset vector and interrupt vectors) As a sanity check, using avr-objdump, that symbol is not defined as 0x0000... 00001186 w F .text 00000226 _ZN5swift9RefCountsINS_21SideTableRefCountBitsEE11doDecrementILNS_13PerformDeinitE0EEEbm Why is gdb thinking the code at 0x0000 is in some other, random function? (It seems to change all the time, one random symbol after another, different each time I start a debugging session like this!)
