USB device firmware upgrade

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

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
directly...

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,
Boki.
