There are plenty of automated tools to create intel hex or srecord
utilities (objcopy, SRecord utilities etc), but you can
also tell avrdude to read a binary ("raw") file:

        -U eeprom:w:<filename>:r

Maybe one of these approaches would be simpler than hand
creating srecord or intel hex files.
