Hi All

What is the function of the execute FW button in the programming tab of Management studio?

Kind regards

    The Execute F/W button returns the gauge to normal mode from ROM mode.

    Hi Thomas.
    Thank you.

    I have a problem. I find that I need to stop my MCU from talking to the bq34z100-g1 when I program the device.
    If I do not do that I lose the bq34z100g1 and have to place a new bq34z100-g1 on the board.
    What is the correct way of programming the bq34z100-g1? The EV2300 with Battery Management studio is not working reliably enough for me to go into production. I have to program 200 units shortly. We have lost close to 10 bq34z100-g1's

    What tools are there to do it properly or what is the spec for the I2C so that I can write my won programmer. The TI tools are a mess.
    Your inputs please
    Ben

    You will need to halt all outside communications on the I2C bus when programming the bq34z100-G1 device, otherwise the flash memory can be corrupted. The bqStudio and bqProduciton tools can be used to program the srec into your device. We also offer the df.fs format file to use with your own tools. It is a text file that contains the I2C commands and data to program the data flash memory.
