I operated according to the video, but it was unsuccessful to calibrate the voltage. 5000mV  Cannot be set to 10000mV。4008mV  hasn't doubled.The register situation is shown in the figure.VOLTSEL =1,CAL_EN=1

    Hi Zhang,

    Please update to the latest version of bqStudio (bqstudiotest).

    It looks like you have been locked from dataflash writes by the flash update ok volt setting. Please also set flash update ok volt to 0 during this testing to ensure that dataflash is able to be written to. Also, configure num of cells in series to = 1 until after calibration has been completed.

    The order is important here so writing to the dataflash isn't prevented.

    Sincerely,
    Bryan Kahler
