RE: [AVR-Chat] Migrating from ATmega8535L to ATmega16L

2004-12-01 by Andrew Lim

Hi John,
 
I have tried checking my interrupt vectors and stacks. I have no problem with these cos I'm using .EQU labels. Any changes in the address will be replaced when I use m16def.inc
I have also changed the rjmp and rcall command to jmp and call. But still not working.
 
 
Anyhow, I will try if I can make it alive. Will let u guys know. Thanks.
 
 
Regards,
Andrew

Check your interupt vectors and stack location. Also
it looks as if you are going over the 8k page boundaries,
(call an jmp instead of rcall and rjmp) so there may be some
problems there. Check your list file to see were the program 
is now located. You should be able to do some simulation in
Studio to see what happens after reset. I may be working
on a project that will start with the 8535 but may end up
with a M16 or even M32, so I would be interested in your
results and findings.

Regards

John Samperi
