I configured the "AFE Cell Map" in the following way:

Now, my eval board do not boot-up.

Is there any way that I can return to previous state. I am using 12 cells, and I am NOT using Cell 4, Cell 9, and Cell 14.

Thanks in advanced

    Hi Jorge,
    I don't have bqStudio open but I think you have most of the 1's and 0's reversed in the cell map. To keep the board awake so that you can change it see section 6.4 of the bq76940EVM user guide, add some simulated charge current. If it won't let you update because of the reported voltage you may have to re-program firmware and then set the AFE Cell map correctly.

    Thanks for your prompt answer.
    I need to re-program firmware, because it won't let me update it.
    The programming instruction mentioned a .srec file. Where can i find this file?

    Instructions:
    "Click on the Firmware button at the top of the window to select the firmware view. Click on the
    Browse button right of the program window, navigate to the .srec file you stored and select the file.
    Click on the Program button. Wait for the programming status window to close, typically about 45 s."
