Prashanth,

No, we don't have a SPI example which talks to SD-card.

The example available in C2000Ware is all we have with respect to SPI examples.

Prashanth,

You can look here in C2000Ware:

C2000Ware_XXXX\utilities\third_party\f2837xs\fatfs\
C2000Ware_XXXX\device_support\f2837xs\examples\cpu1\sd_card\

Both the SPI and SCI example code which communicates with SD-card uses FAT file system. If you don't want to use that FatFs file system, you need to develop your own code.

Sorry, I haven't tried doing something like this myself. You may need to try it on your own.
