File format byte by byte[edit | edit source]
All multibyte integers are stored LSB first.
GDF version 300[edit | edit source]
Header[edit | edit source]
IDString - 4 bytes, always="GDFW"
BLFileVersion - 2 bytes, value=300
TargetDriveType - 2 bytes, Argon=4000, Ion=11000, Atomi=14000
HostFWbytes - 4 bytes, number of bytes for STM32 CPU
GCFWbytes - 4 bytes, number of bytes for GraniteCore CPU or 0xffffffff if not included
Data[edit | edit source]
Data of HostFW begins. Amount of bytes is HostFWbytes
Data of GCFW begins. Amount of bytes is GCFWbytes
