BQ27Z561-R2: Is the golden image file include Chemical ID?

Hello, 

Please ensure that you have correctly programmed the chemID before generating the golden image, and ensure that there are no errors when you are programming the chemID.

Jonny. 

Dear Jonny

 Thank you for your reply.

 We think the chemID is programmed correctly.
 And, there are no errors when we are programming the chemID.

 We confirmed that the chemID changes to 2151 when we write the attached .bq.fs file generated thgether with the .gm.fs file from the bqStudio to the BQ27Z561-R2.
 Then, we confirmed that the chemID does not changed from 2151 when we write the .gm.fs file from the bqStudio to the BQ27Z561-R2.
 The chemID did not change back to 1210.

 What is the difference between the .gm.fs file and the .bq.fs file?

Dear Jonny

 Thank you for your answer.

 I understood that the .gm.fs file is used for the fuel gauge types with fixed CHEM_ID, such as the BQ27421-G1.
 The difference between the .bq.fs file and the .df.fs file is that one includes firmware (.bq.fs) and the other does not (.df.fs).
 In what situations do you need to rewrite the firmware?

Best Regards,
