MMU2 firmware verify error
I can't flash my MMU2. Always finish with an error message:
avrdude: verifying ...
avrdude: verification error, first mismatch at byte 0x0980
0xff != 0x1f
avrdude: verification error; content mismatch
avrdude: safemode: hfuse reads as D8
avrdude: safemode: efuse reads as CB
avrdude: safemode: Fuses OK (E:CB, H:D8, L:FF)
avrdude done. Thank you.
It doesn't matter which firmware I use, all of them fail. Now my MMU2 unit is unsuable.
I have tried different cables, to reboot PC and printer, full reset printer, now I have no ideas.
What can I do?

I have a similar error when flashing mmu2s firmware. Did you ever find a resolution to your issue?
RE: MMU2 firmware verify error
I would contact Prusa supports and link this page to them
RE: MMU2 firmware verify error
Update: Got some live chat tech support today and Prusa is shipping me another MMU2S electronics board and cable...Hopefull this resolves the verification error when flashing...
