ATMega128 creating new board

Hi All,
I developed a board which use ATMega128 microcontroller and I need to use multitasking, and my choice was using ChibiOS.
I used ChibiOS_2.6.0/demos/AVR-ATmega128-GCC as base, I removed the Serial Communication and Second Thread, so just the main() running ( it should run
), but it looks like then the uC goes to infinity loop when the halInit() executed before the main(). I modified the board.h and board.c (ChibiOS_2.6.0/boards/OLIMEX_AVR_MT_128), but I just modified the Pin configuration that which pin is input or output. I keep the TIMER0 interrupt settings and anything else. The Clock of the uC comes from a 16MHz Crystal, I set the fuses correctly.
The source compiled without any warning or error.
Have somebody any idea, why it is goes down?
If anybody need further information about the problem please let me know.
Thanks in advance.
Regards,
Gergo

Hi,
Changing the board files should be sufficient, where exactly the code hangs? you should be able to see that using the debugger. You may also try posting the diffs with the standard demo.

Hi Giovanni,
Unfortunately I don't have debugger, so I cannot check it. I Set a Pin to high inside the IRQ handler for debugging, and I saw that no interrupt occured.

Hi,
It is hard to give advice without info, I tested that AVR demo just before the 2.6.0 release so the problem is likely:
1) In the code changes.
2) Possible differences in toolchain.

Hi,
I checked the version of GCC, it is 4.6.3, so I will try it on 4.3.0, thanks for the tip. ( I am using the makfile for build )
I have found a hardware issue during the tests (but it independs of the software issues), so now I need to work on it firstly, after that I can check the software issues...
I will post if I have new results...
Thanks,
Gergo
