ATMega 64 troubles

Started by Mario Alberto Melo May 18, 2004
I'm having some problems programming ATMega 64 using CodeVision.
When i click on "Erase Chip" all works right, but when i try to
program flash an error happens, but if I erase chip, turn off power
supply, turn it on again and now program flash i'm able to program
it. It happened to me with few ATMegas 64 in different pcb membedded
designs, but only with 64 no other chip showed that problem
