I generate a .srec file and .gg file. but i find in .gg file there are many difference with my original .gg file. will they impact .srec file, such as lifetimes, Ra tables?

Hi Harry,

Yes, these values will also be included in your srec file. You may want to reset things like Lifetime data to defaults before exporting the srec.

This video is helpful (it is for a different device, the BQ40Z50). The last part covers generating the golden srec for production.

Best regards,

Sorry, I didn't see how to set lifetimes data to default.

So my question is, I dump golden file from a BQ in the field, and modify some parameters I want, then I generate a new golden file and program it into another BQ, is it right? do I need to clear the lifetimes data, such as FW runtime, cell max voltage, No of COV events.

thanks

Hi Harry,

Yes, you need to clear the lifetime data. Otherwise when you program the golden file into a new device, it will have the old device's lifetime data.

You could program this golden file to a new device, use the LifetimeDataReset command (0x0028), then you can save a new golden file. However, I really recommend generating the golden file on a new device following the instructions in the video I sent. The Ra table will have been updated if the field device is on an aged battery, so I would not use these values on a new battery.

Regards,

Matt
