For the bq40z50, is there a data flash storage format similar to those used for 27541 and bq20z40/45 ?

For the bq40z50, is there a data flash storage format similar to those used for bq27541 and bq20z40/45 that holds only binary image of data flash ? I had crafted my own routines to very quickly load such files in production for the 27541 and bq20z40/45, but can only find the *.gg.csf (ASCII) format and *.srec (firmware dump) for the bq40z50. The srec file is so large it takes a very long time to load compared to the old DFI/ROM files.

    Darrel,

    The srec file contains the full flash memory, but you can program just the DF portion to speed up the process. The DF portion is broken into two blocks. The main DF, that need to be loaded, is located in addresses 0x004000 to 0x005FFF and the security codes are located in address 0x140080-0x1400FF. You can load just the data in 0x004000 to 0x005FFF, if you want to set the security codes later.
