I have 3 mega1280 bds previously programmed. Want to shoot new pgm in. Can't enter programming mode, so I can't read devce ID. Two jtagmkiis, one jtagice3, one dragon, one atmelice. I hope my 5 different programmers aren't all bad. I tried AS7 repair. Takes forever, and you have to keep pecking the install driver about 3 dozen times. Any other tips and tricks to try?
