# We cannot currently build a factory image. It is the sysupgrade image

# The header is 2kiB and is filled with 0xff. The format seems to be:
# 2 bytes: 0x0000
# 2 bytes: checksum of the data partition (big endian)
# 4 bytes: length of the contained image file (big endian)
# 32 bytes: Firmware Version string (NUL terminated, 0xff padded)
# 2 bytes: 0x0000
# 2 bytes: checksum over the header partition (big endian)
# 32 bytes: Model (e.g. "NBG6616", NUL termiated, 0xff padded)
# rest: 0xff padding
#
# The checksums are calculated by adding up all bytes and if a 16bit
# overflow occurs, one is added and the sum is masked to 16 bit:
# csum = csum + databyte; if (csum > 0xffff) { csum += 1; csum &= 0xffff };
# Should the file have an odd number of bytes then the byte len-0x800 is
# used additionally.
# The checksum for the header is calcualted over the first 2048 bytes with
# the firmware checksum as the placeholder during calculation.
#
# The header is padded with 0xff to the erase block size of the device.
