Dear Sirs, Does anybody add SD support for any architecture? I found various uRTOS with a uFS support for example for FAT12/16 and SD. Do you know where I could find a starting point to implement a filesystem … I thought to have a look at linux source…. Regards, Vento

If you just want to read and write to a flat file system (no folders) then there is a circuit cellar article with source code that can be purchased for a couple of dollars.  There are a couple of functions to implement for the SPI interface.  Once these are done it works really well.  Took two days to get working!

could you please indicate me a reference to that item? Thanks

Just googled for it and got it as the top link. http://www.circuitcellar.com/magazine/176toc.htm, second down the page.

thank you, I’m going to get it
