Verification error in program upload - orion board

#1

Hello, at the end of the process “upload to Arduino”, it looks me this message:

avrdude: verifying …
avrdude: verification error, first mismatch at byte 0x0000
0x62 != 0x0c
avrdude: verification error; content mismatch

avrdude done. Thank you.

What happened?

I have just updated the firmware.

Thanks

Hi

The Me Orion board may lose the Bootloader. You can upload the Blink program to test it again refer to this post.

If there is still the same error message, it lose the bootloader and you can refer to that same post to re burn the bootloader for it if you have another Arduino board (Arduino uno, Me Orion or me mCore).

It would be extremely helpful to know WHY it may lose the bootloader.

Hi igorsales,

Normally, the static electricity will cause the board lose the bootloader.
During our normal use, try to avoid touching the chip by hand.
