Hello,
I am evaluating bq27541-G1 and I read that there are some chemistry data in the flash that are updated when the chemistry ID is changed using bqCONFIG software. I understand that these chemistry data are hidden data and are not visible using for example Gauge Studio or bqEVSW and are not exported in gg file. So I have some questions about these chem data:
- Is not possible to read or write these data into flash with device in firmware mode using the flash access mode described in bq27541-g1 datasheet ? Is there a subclass ID associated ? Is ROM mode the only way to update these data ?
- is possible to know these data for Chem ID 0107 ? what is the difference with default 0128 ?
- where are they located into dffs and dmi files ?
- Is there for dmi file format a document similar to the one available for bqfs and dffs files (SLUA541A) ?
thanks in advance for your replies
Stefano
