bq40z50 / how to update tobq40z50

Hi all.

I installed update to bq40z50-r1 file(.srec file) using EV2300,
but I couldn't program bq40z50-r1 srec file to bq40z50 EVM.

Please tell me how to update.
If you have the document, please give me.

I installed the new package for the bq40Z50-R1 (Located at:http://www.ti.com/lit/zip/sluc585 ).

Best Regards,
