Argon firmware file contains embedded software for Argon (servo drive). Firmware file is generated by makefirmware utily.
File format byte by byte
Header
IDString - 4 bytes, always="GDFW"
BLFileVersion - 2 bytes, current=300
TargetDriveType - 2 bytes, Argon=4000, Ion=5000
HostFWbytes - 4 bytes, number of bytes for STM32 CPU
GCFWbytes - 4 bytes, number of bytes for GraniteCore CPU
Data
Data of HostFW begins. Amount of bytes is HostFWbytes
Data of GCW begins. Amount of bytes is GCFWbytes
File checksum
FileCksum - 4 bytes cacluated from the current file. Simply sum of all unsigned bytes in file except CKSum itself
