I am using Cypress PSoC 3 and 5 MCU'S. Can anyone tell me of a good resource to understand how to read and write correctly. I would like to store data on the card and later retrieve this data possibly using a flash to USB converter.
 

You did not mention which MCUs you use. What are they and do you have a preference?

The basic interface and driver code are not difficult, however using a FATFS can be challenging depending on the version.

Here's a few tutorials:

FatFs Generic FAT File System Module



If you have a preference as to which MCU you wish to first implement the SD interface and FATFS, let me know I have other examples.

Hope the info helps,

The original post refers to Cypress PSoC3 and 5, using 8051 and ARM Cortex M3 core respectively.
 

I stand corrected, I misread the original post as meaning PSOC3 and 5 other MCUs.

Here is tutorial covering the interfacing of SD cards with 8051 for your PSOC3:



The tutorial uses the "FatFs Generic FAT File System Module" available from the link above.
