RE: [AVR-Chat] Re: Bootup/reset very big problem

2005-02-03 by Javier Fiasche

Guys, another clue..........
I changed the fuse bits to run with thew internal clock at 8 mhs and it did not start even with the isp programmmer connected
i cahnged it back to run at 1mhs internal and the only way i could make it run was with the isp reset....
Ideas???
Thanx
Javier
