We are working on a C6745 project that will have USB connectivity. The system bootloads from SPI flash and executes out of internal SRAM. Assuming all this makes sense, we want to connect to the PC over USB preferably using Mass Storage Device class. As far as I can tell this is all supported by the BIOSUSB package for NAND flash ... BUT -- we want to load small files onto SPI flash. Is there a way to use the MSC with a 'file system' on SPI flash?
1. use USB to communicate with the PC/MAC
2. download coefficient files onto SPI flash from the PC/MAC
3. access the coefficient files on the SPI flash and move them to SRAM for execution.
Can someone point me in the right direction?
Thanks,
Cliff Elion
