3) upload the firmware using mt7681_uploader.py, setting -f to specify the firmware
generated in the previous step, and -c to identify the new COM port, as shown below:
> python mt7681_uploader.py -f out/sta/MT7681_sta_header.bin -c
/dev/ttyUSB0
4) successful upload of the firmware will result in the following being displayed:
Recovery Mode entered, Starting to upload...
