# This script prepends header to marvell FW

# Header is needed during reading FW from flash

# It specifies mainly length of FW, but contains other

# information that are not necessary but convenient to have

#

# It takes the first file in src_data/marvell_fw as a FW, so only one

# file should be always in this folder

#

#

# Header is formatted like this:

# 4 byte magic number - binary form of ascii string "MVFW"

# 4 byte unsigned integer offset of FW in the flash (related to header start)

# 4 byte unsigned integer length of FW

# zero-ended string of creation date

# zero-ended string name of file with FW

#

# Script is supposed to be placed in outputs directory.

# It is independent of opened project.

#
