Switch from ADSP-218X to Blackfin?

We have been using the 218X parts (quite satisfactorily) but are considering tooling up for the Blackfin. This is a big step for us because it involves shelling out $4300 for an emulator and VisualDSP++ software. Hardware-wise the 218X family still services our needs and price-wise still compe...

USB mass storage device on blackfin?

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. I...
