Hi all, I wanna ask for someone who has experience on developing port for AVR architectures. I got the port files for AT90CAN on a professor web site available on this forum at I’m using the gcc compiler but at successive external interruptions my application suddenly stop, I mean when I use the int0 in order to count the number of pulses in a time interval my threads got stuck. It doesn’t happen when I run the same application on Atmega128. 
Have anyone seen that behavior before? Could it be relationship with the compiler?
If anyone has another port for this processor could turn it available?

Hi Breno,
maybe You don’t have stack in internal RAM.
More in errata for AT90CAN (Miss-functioning when code stack is in XRAM).
