Hallo,
ich habe ein Problem mit avrdude 6.3 (Debian stretch)
Egal, ob ich fuses lesen oder ein Programm schreiben will,
bricht avrdude mit folgender Fehlermeldung (unknown command)ab:

avrdude done. Thank you.
Nach diversen Tests, habe ich avrdude 6.1 installiert, und alles geht
wieder wie gewohnt.

avrdude done. Thank you.
Das ganze passiert bei 2 Programmern.
Diese sind identisch.
Da ich diese selber gebaut und das Programm geschrieben habe,
denke ich, daß die Ursache in einer neuen Funktion von avrdude liegt.
Nur weiß ich nicht, wo ich ansetzen soll, da mir selbst -vvvv
nicht weiterhilft.
Das gesendet Kommando, wo der Fehler auftritt, sieht meiner Meinung nach
OK aus.
Kann mir jemand mal weiterhelfen?
Danke
