Hi!
I am using stm32f723 to implement usb device mass storage.
I try to mass storage using an internal flash, but I get a message that the formatting is not complete.
I have developed it by referring to the link below, and I have confirmed the same value for reading and writing.
But it is doesn't working.
​Can someone please confirm?
I put the file in the attachment.

The large flash sectors, and erase times, make the internal flash of the F7 series ill suited to a FAT/MSC solution. Consider external flash memories with smaller erase block sizes, eMMC chips designed for such tasks.

Thank you.
The test product does not have an emmc or nand, so I'm testing it with an internal flash to check some actions.

Then you'll need to manage the deblocking​ and partial writes to flash sectors holding existing data.
