The .flash file should contain initialisation data for only part of the flash. The SREC address records describe offsets from the start of the flash chip. If you write the .flash file to flash using the flash programmer then the contents of locations not described in the .flash file should remain unchanged.

So your software should do the same, if an address is mentioned in the SREC file then write the appropriate data there, if it's not mentioned then leave it unchanged.
