Date: Sat, 22 Oct 2005 01:13:00 -0000 [thread overview]
Message-ID: <20051022011300.YzflqcnCiKzPY3PZeKLhwdrFc8g85Ul6E7-lAdYP2Pg@z> (raw)
I use macraiger gcc port for PPC. When I compile my software with gcc -O0
zero the program work as excpected
But I as soon as I use optimization option like -O2 my software crash. I
can't figure what case this until now. My assumtion is that the stack is got
currupted.
I use uC-II RTOS as a kernel.
Has someone experience such case?
Have someone some hints for me?
Thanks,
Amir
