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.
