# The BL616 has to be in its ROM USB bootloader ("Bouffalo CDC DEMO"). The
|
|
# script gets it there by itself when this firmware is already running
|
|
# (serial port opened at 1234 baud). Otherwise, unplug the board and plug it
|
|
# back while either
|
|
# - holding the S3 button (this firmware is installed), or
|
|
# - shorting the TDO test point to 3V3 (bottom side, always works).
