USB MSD IMPLEMENTATION

[madhukar]

I want to create a MSD using STM32L053 controller and external data flash with SPI interface .
No of files are very limited and hence I want to use FATFS system.Created files are stored in data flash.

I AM LOOKING FOR REFERENCES AND EXAMPLE CODE TO IMPLEMENT THIS SYSTEM
