Part Number:BQSTUDIO
Good morning,
I would like some clarification on using bqStudio for production programming of a gas gauge. Mine specifically is the BQ28Z610, however I did not categorize this post under that gauge since it is targeted at programming in general and the software features.
From what I can tell, I've only seen the possibility to export from or import and write to the data flash settings using a "*.gg" file. This is assuming that the default firmware will be used although bqStudio also allows the use of an "*.srec" file for updating the firmware. Aside from those two file formats, I do not see any option for "*.dfi" file which is supposed to be used as a "golden file" for production phase. I believe my understanding of this is correct, but otherwise please correct me if not.
My question is somewhat two-fold. First, is using the "*.dfi" file for production programming essentially the same as programming the battery chemistry, writing to the data flash with a configured "*.gg" file, and fully cycling the battery a couple times so the gauge can learn the battery characteristics? From a file extension description document I found on TI's website, it is not recommended to use a "*.gg" file as a "golden file". This transitions into my second question... if a "*.gg" file is not supposed to be used, how is production programming accomplished with the bqStudio software? I am aware of how to submit the necessary data in a zip folder through the GPC online tool, but to my knowledge that will return an optimized "*.gg" file, not a "*.dfi". Most of what I know on this topic has been obtained from a hodge-podge of documents on TI's website which sometimes mention other software programs/tools to use. If you could help elucidate this production programming process for the gauge I am using with bqStudio, I would appreciate it.
Thanks
