Accessing external memory

Priyadarshini Uthayakumar

Hi all

I am presently working on accessing external memory. For my project, I have to find the address of a file stored in SD card.I am using ARM controller. I am using KEIL MDK to program it.

Can anyone help me in finding the location.

Thank you in advance.

    You didn't get what the first responder was trying to tell you. You're mixing apples and oranges there.

    An SD card is not what the term "external memory" refers to. Not in modern-day microcontrollers anyway, where memory is usually internal to the chip, so external memory would be RAM or ROM connected directly to the controller. An SD card is mass storage. Whole different kettle of fish.
