BQ28Z610-R1: DFW故障

Part Number: BQ28Z610-R1


电池电量低,外接充电时读取到DFW故障。请问哪些原因可能造成DFW故障,需要怎样避免。

PF_clear不能清除故障,重新烧录程序后恢复正常。

  • 您好 ,请参考下面内容:

    This permanent failure occurs if a write to data flash was unsuccessful for any reason. You can try using the PermanentFailureDataReset command (0x0029) to see if it is possible to clear this failure. However, the error may occur again if there is a true dataflash issue in the device.
