BQ27Z746: 0.01 build 12 and 1.02 build 15 or 1.05 build 18 Data Flash Map varies and is not documented properly for R1 in SLUUCW8

Part Number: BQ27Z746
Other Parts Discussed in Thread: BQSTUDIO

Tool/software:

Files SLUUCA6 (BQ27Z746 Tech Ref) and SLUUCW8 (BQ27Z746-R1 Tech Ref) both document the same address space for Data Flash, but corresponding FW versions 0.01-build-12 Data Flash map differs from 1.02-build-15/1.05-build-18.

Is there an updated address map for Data Flash available?

Hello,

I recommend referring to bqStudio for the latest byte and bit mapping of the registers.

Regards,

Robert.

I could not find the register addresses of the data flash (labelled Data Memory in bqStudio). How can I find it there.

Hello,

One solution you can try is to have an I2C logic analyzer on the I2C lines, then you can write to the desired parameter using Data Memory in bqStudio and use the logic analyzer to determine which address the desired parameter corresponds to. Otherwise you would have to refer to what is labeled in the Technical Reference Manual.

Robert.
