BQ35100: Chemistry programming, error code 1709

Part Number: BQ35100
Other Parts Discussed in Thread: BQSTUDIO

Tool/software:

Hi Experts,,

I am trying to program a chemistry profile to BQ35100 for Battery (Make: Saft, Capacity: 13000mAh). I am using the BQ studio latest version 1.3.127 and Chemistry version: 1099. But after selecting my Battery's profile (Battery profile ID: 0659) and clicking "Program Selected Chemistry", I receive an error with code: 1709 (Chemistry programming failed. The chemistry signature doesn't match signature calculated by firmware).

I have also updated the Chemistry version to latest one i.e. 1121 but still same error persists.

While tried to load another Battery's chemical ID (profile ID: 0648), it got programmed successfully.

Please suggest on how to proceed with programming my required Chemical ID: 0659.

Regards,

Hello Joselito,

Ask the customer to check when after programming ChemID 0659, go back on the register screen and send the "CHEM_ID" command to see what the results is. It is possible BQStudio is throwing the error code, but the ChemID got programmed successfully.

Adrian

Hi Adrian,

No, it shows the last successfully programmed Chemistry ID upon issuing the "CHEM_ID" command. As I mentioned, I can program ChemID 0648 but while I try to program my desired ChemID 0659, I get the error code: 1709. Now if I issue the CHEM_ID command then it replies with ChemID 0648 (the last which is programmed successfully). I need more help on how to program my required Chem ID 0659.

Regards,

Josel
