Hi Guys,

             

Newbie here, I've am working with SAM L21 Xplained Pro board. I tried interfacing an 8GB SD card to the board and used the ASF FatFs Example to create a file. But it doesn't write anything to it. I'm not using the  I/O1 Xplained Pro extension board (which comes with a 2GB SD card). Can someone tell me if its possible to write to an 8gb SD card using the ASF example Driver?

 

Thanks in advance guys,

If the underlying FAT driver is FatFs then it should have no problem with 8GB. So if isn't working check low level signals, wiring, etc.
