    The most likely reason is because the parameter "Flash Update Ok Voltage" is set higher than the voltage observed at the BAT pin of the device. If you follow the steps in Section 3.2.1 of the EVM User Guide, you should be able to update this parameter so that you can write to the data flash.

    Best regards,
