Eroare scriere fusebit


Recommended Posts

Incerc sa scriu fusebiti inntr-un Attiny25 si imi da urmatoarea eroare:

 

Writing FUSE area ... Error writing fuse: written 62, read FF
Error writing fuseH: written DF, read FF
completed, 2 errors
End (0.06 s) 2 errors
Folosesc un programator openprog.
De ce nu pot scrie fusebiti, mentionez ca cipul e nou si are toti fusebiti FF, implicit nu pot scrie nici softul, pentru ca imi da aceste erori.
A mai intampinat cineva aceasta problema?

A aparut la prima scriere.

Programatorul functioneaza bine. Si eu am suspectat prima data programatorul, dar am scris cu el un Atmega8 si un Atmega16 si totul a decurs normal.

Nu imi dau seama unde poate fi problema.

De citit il pot citi si imi toti fusebitii setati la FF, iar codul si eepromul mi le arata ca sunt goale.

Cand incerc sa scriu hex-ul si fusebiti imi da acea eroare, ca incerc sa scriu 0x64 si el citeste 0xFF
