The communications between flash drive u-disk and cy7c67300

Hi,

    I’m a new developer about the firmware of cy7c67300. Presently, I have no idea about how to write a firmware which could make the cy7c67300 read data from a flash drive u-disk. I have read the cy3663 and cy4640 development kit documents for a month, but I still don’t know how to build a frame about my project. I have tried to download the msc code in the cy4640, but it doesn’t work expectly. I want to ask you if there were some firmware in the cy3663 and cy4640 that I can modify and use them in my design. Can you give me some help? I will appreciate very much!

You should find http://www.cypress.com/?rID=12902 useful. It shows how to use a SPI controller to do USB mass storage drive related tasks using Ez-Host (CY4640).

Anand
