Not wishing to start a holy war ;o) but as an ENGINEER I can not condone running parts out of spec. I also dislike people complaining of problems when they run parts out of spec. I agree a lot off people do it, but try reliably accessing the EEPROM when over clocking the AVR (btw this is the main reason the AVR's are speced at the speeds they are) I accept in your case that once the device had its crystal replaced it still did not work. There are only 2 fuses on 8535 (Short start-up and ISP disable) Regards, Kat. > -----Original Message----- > From: Jack Valmadre [mailto:jack.valmadre@optusnet.com.au] > Sent: Wednesday, 28 January 2004 5:18 PM > To: AVR-Chat@yahoogroups.com > Subject: RE: [AVR-Chat] RESET problems > > > It is an AT90S8535, however replacing the 10MHz crystal with > an 8MHz crystal did not fix the RESET problem.
