BQ40Z60: how read CC Gain from dataflash ?

Part Number: BQ40Z60
Other Parts Discussed in Thread: BQ30Z55

Dear TI Expert,

My customer is trying to use their own production tools to take the MP of BQ40Z60. Their tools and codes in PC works well on BQ30Z55's MP, however, when use the same code, they can't read out the "CC gain" from dataflash of BQ40Z60. Could you kindly give some advice what's the difference of "CC gain" between BQ30Z55 and BQ40Z60, how to change to code to meet BQ40Z60's requirment? Thanks a lot.

  • Hi Bruce,
    The access method for dataflash is different between bq30z55 and bq40z60. bq30z55 uses the subclass method to access dataflash, while bq40z60 uses direct addressing.
    Are they able to read other dataflash parameters from bq40z60 and are they only having trouble with CC Gain?
