I am trying to run a sample application on ATSAM21DJ18A. The sample application tries to access a file present in a USB Host Mass storage device connected to ATSAM21DJ18A kit.
I have taken the source code from an example project available in the internet. (Link: http://www.atmel.com/images/atme...)
However I have not tasted success while trying to implement this project at my end. I found that f_mount call returns FR_OK where as f_read call always returns FR_NOT_READY. I am new to ATSAMD21J18A. Can someone help me out with figuring out what the issue actually is ?
I am using ATMELSTUDIO 7.0 for implementaion.
