Don't thank me yet.  The answer to your question has a hint of sarcasm (but it's the only answer anyone can provide at this point)...

avrdude: stk500_paged_write(): (a) protocol error, expect=0x14, resp=0x64

The error means exactly what it says.  avrdude was attempting to write (hence the "stk500_paged_write").  While attempting to write, it expected the programmer to respond with 0x14 but instead received 0x64.


Do you program the robot through a bootloader installed on the robot or through an in-system program (aka "ISP" aka "ICSP")?

How do you know they are burnt?

Are they 'open', 'short'

do you have a 'close-up'

This relates to the  motor drivers, try disconnecting the motors, then re-try the upload.
