Create Data Partition with FAT on external QSPI flash for saving WAV file and playback

[dkybchoi]

Dear All,

As captioned subject, we would like to use XU chip to implement audio recording and playback functions and support USB Mass Storage Class ( i.e. user can write or delete WAV file from PC ) . My questions are :

1. For example using sample rate 48KHz and one stereo audio , is it feasible to use external QSPI flash with data partition as storage device to support live recording and playback. ( RAM buffering may be required , using external SDRAM is an option )
2. According to AN00125_mass_storage_class, there is no File System supported. Is there any reference to implement file system ?
3. Is it possible for having USB Audio Device and USB Mass Storage Device coexist ?

Thanks
