Hi all, I wonder if anybody implemented a USB mass storage device functionality on a ADI blackfin architecture. The blackfin would be connected to a flash via the asynch memory interface, and have some USB hardware, say, a MAX3420. I guess the critical part is to manage the flash wear. Is there any free implementation or App-note around? Best regards, Andre

If the low transfer rate is not an issue, you can use VC1L host from FTDI. It takes care of all mass storage USB functionality.> I guess the critical part is to manage the flash wear.
