NOR Flash and Keil File System Middleware

zzr

I am evaluating the Keil File System Middleware. I have encountered a problem. Hopeful someone could give me a quick and clear hint.

It seems there are two types of file systems in the FS middle ware: Embedded FS and FAT FS.

Could someone tell me the differences between this two types.

I have noticed that NOR flash type be configured to use the Embedded FS type.

Could this Embedded FS be compatible with the USB Mass storage Class?(Treated as a plugged U Disk by the PC).

Could NOR Flash be configured to use the FAT FS? I have noticed the open source FAT FS doesn't distinguish the NOR Flash from other storage media.

Could a pure SPI Flash(i.e. Winbond W25Q32) be configured as the NOR Flash? The official Keil Pack includes a special NOR Flash(AT45DB642D) which supported both bus style NOR flash access method and a SPI style.

Thanks.
