MMU2 firmware verify error

Jan 05, 2019 11:14 am

I can't flash my MMU2. Always finish with an error message:

Code: Select all

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?
