BQ27520-G4: Update status change from 0 to 2 during learning cycle

HI

That is not abnormal behavior. You achieve update status of 02 if the battery has learnt. It is likely you may have had a resistance update occur before qmax update hence update status going from 00 to 02.

thanks

Thanks Onyx.

I compared and found that only the values in Ra0 Table and Ra0x Table changes after the learning cycle. The values in Ra0 Default and Ra1 Default remain unchanged. Am I right to say my data are good to be used for the golden file? Should I copy the value in Ra0 Table to Ra0 Default, Ra1 Default, Ra1 Table, Ra0x and Ra1x Table?

Also, I just need to change all the "Update Status" value to "2"?    

What is the function/difference between Ra0 Default, Ra0 Table and Ra0x Table? I could not find any description in the TRM. Thanks.
