I m trying to implement card reader on lpc1768. My usb part is almost done. Working ok. Right now i m facing below problems:
1) sd card i m using in card reader is 2GB which gives me 1.86 GB usage memory.I added two files in the card those combine to use 64 kb. But windows shows 465 MB is used and 1.40 gb is free memory available. 2) I m facing bit problems in read/write multiple block commands.I tried multiple block read command. I successfully able to receive 1 block.while reading second block i receive token 0xC0 not FE.What that means?
