    Hi All,
    My DFU program almost be completed ( 80%) but not very reliable

    Q:I want to know the USBCore will broke or not if my upgrade procedure is
    not complete?

    QBQ: USBCore will save the download data first or not? or FLASH the new data

    What will exist forever is only bootloader. ( Unless clear it from SPI )

    Even I can do DFU, that not means my firmware still healthy.

    Best regards,
