# Generate a version blob for

# Usage:
# versionblob.py --append --firmware=<Firmware file name> --boardid=<Board code>
#
# append: if present, then append blob to firmware file directly, otherwise create "blob.bin"
# firmware: the filename of the firmware binary
# boardid: as a string, the board code, for example "0401" for CC board version 1.
# should match the codes in firmware description files.

# We have 100 bytes for the whole description.
#
# Only the first 40 are used by the firmware, the remaining
# Only the first 40 are visible on the FirmwareIAP uavobject, the remaining
# 60 are ok to use for packaging and will be saved in the flash

# Structure is:
