I tried to update my printer (CR10S) from Marlin 1.1.9 to 2.1.x with octoprint (from usb) and the firmware updater.
But I can't do it, it keep to fail when verifying the memory.
The log shows:
avrdude: reading on-chip flash data:
avrdude: verifying ...
avrdude: verification error, first mismatch at byte 0x0002
0xda != 0x42
avrdude: verification error; content mismatch
avrdude done. Thank you.
Did anyone have encountered this error ? I have scroll all website i could find but can't find a solution.
Have a great day !
