Исправление Zubok, (текущая версия) :
avrdude: verification error, first mismatch at byte 0x0000
0x01 != 0xff
avrdude: verification error; content mismatch
Это нормально. Так и должно быть. Значит, fuse правильные.
Note that some numerical values refer to fuses containing undefined bits (set to '1' here). Depending on the target device these fuse bits will be read either as '0' or '1'. Verification errors will occur if the values are read back with undefined bits set to '0'. Everything is fine if the values read from the device are either the same as programmed, or the following values (undefined set to '0')
