[Simulavr-devel] AVR-GDB inerrupt debugging problem

[Radovid Drobnjak]

Hi,

I would like to debug a simple PWM program for atmega128, and I cannot  
find out why the simulator does not trigger the interrupt function  
(TIMER2_OVF_vect).

I've checked the registry settings of the program few times and all seems  
OK to me. But the thing what puzzles me even more is that I've tried to  
simulate the program in avrora (without GDB, as the support for gdb there  
is not so good) observing the OCR2 registry and all seemes to work fine,  
as the mentioned registry was updated acording to the expectations (it is  
updated inside the interrupt function).

Is it a bug or something, or I've missed something?


here are the last few lines of the -G option:

 gdb -> Ack
Recv: "$s#73"
 Ack -> gdb

THX in advance
