Some reference FAQ entry.

  1. How to read the fuse settings with avrdude 7.0 and later?

Ref: https://github.com/avrdudes/avrdude/issues/965

If you want to do more, try "terminal mode" (-t). You can browse around interactively through your device, including the fuse values. Non-interactively, it would need -U options, like:

avrdude … -U lfuse:r:-:h -U hfuse:r:-:h -U efuse:r:-:h

  1. JTAG could not write 1s to EEPROM. Ref: https://github.com/avrdudes/avrdude/issues/1072

  2. Write flash rarely works in terminal mode for classic AVRs Ref: https://github.com/avrdudes/avrdude/issues/1020
