avrdude: verification error, first mismatch at byte 0x1d00

avrdude: verification error, first mismatch at byte 0x125c

I merged the post above from @alfahad re: "avrdude: verification error", into this thread. Where Joel has some related uploading tips.

Errors can happen because we are doing the programming over-air with avrdude.

avrdude: verification error, first mismatch at byte 0x4500

avrdude uploads code to the PIC and ATmega at 115200 baud.

I was able to program bootloader UDB32-MX2-DIP.hex from:https://github.com/chipKIT32/PIC32-avrdude-bootloader/tree/master/BootloadersCurrent-hex
