i am trying to create an application so i can use the sdcard as a drive when connecting my board to a computer.
i am using a samd21g18a.
i am also using the atmel ASF.
i have added the sd-mmc library and the usb library ( composite mode), but i am unable to access my sdcard.
i checked the signal SCK but nothing.
is there any thing i have missed?
thanks for the help.
