# Serial firmware uploader for the PX4FMU bootloader
#
# The PX4 firmware file is a JSON-encoded Python object, containing
# metadata fields and a zlib-compressed base64-encoded firmware image.
#
# The uploader uses the following fields from the firmware file:
#
# image
# The firmware that will be uploaded.
# image_size
# The size of the firmware in bytes.
# board_id
# The board for which the firmware is intended.
# board_revision
# Currently only used for informational purposes.
#
# AP_FLAKE8_CLEAN
# for python2.7 compatibility
