Accessing data from SD card to test ARM executable

Hi all,

I am using beagle board revc3,

and i have compiled ARM application code as U-boot standalone
application and placed in the SD card.

I have changed boot order to boot from SD card, then command given to
load the U-boot standalone application.

Now how can I continuously get execute this image on board for
multiple inputs from the SD card.

Is there any commands or procedure, please suggest me in it.

2. Is it possible to read SD card data from ARM application, when ARM
application has not compiled as U-boot standalone application ?

Thanks & Regards,
