    Hi Eddie,

    the Customer needs to program the chem id on the device, configure it per their application and then perform a learning cycle. The TRM has details on the learning cycle. After that is successfully completed a golden srec or flashstream (bqfs or dffs) file is extracted. This will be use to program multiple unit 

    thanks

    Hi Onyx,

    Yes, they have completed the golden srec already.

    What are the recommnended hardware/software tools and procedures to program the units at mass production?

    Hi Eddie,

    The customer ought to use their host to parse the flash stream file (bqfs or dffs) to the gauge. See app note attached.

    thanks

    Hi Onyx,

    Customer is setting up production line procedures to manufacture their product with BQ27Z561. These are manufacturing engineers asking question, not R&D. They do not intend to use MCU/Linux to program BQ27Z561. In this context, here are the specific questions:

    1. What is the hardware tool? For factory mass production.

    - EV2400? Any other recommended hardware programmer tool? (They are thinking in context of flash programmer tools)

    2. What is the software tool?

    - Any GUI to control the hardware tool?

    Hi Eddie

    Unfortunately, we do not have such hardware tool or software tool. Customer build their own setup for parsing the flaststream file on the device. 

    We have bqproduction-single cell, but that does not support this gauge.

    thanks
