Reading Data from SD card and put it into memory/BRAM

Hi

I am working on a project i.e shape recognition using the Zedboard. So I need to pass in the image as an array of bits in to the board; To do so I would like to store the images into the on board memory some how.

So I had the following ideas :

1) Storing the image SD card externally and the using VHDL to read the sd card would be the way to go but I am not able to find any resources which will guide me about the above.

2) Use Xilinx SDK to write the image to the DDR3 or the Flash memory/BRAM and then use VHDL to read from there, but sadly the only information I found was to write the boot files in to the flash. So no luck there either.

Any ideas how I could solve this??

Thanks in advance!!

On ZedBoard, the SD Card is connected through MIO directly to the PS, so you will not be able to use VHDL to directly access the SD Card. You will need to use the ARM to access the SD Card and then copy the information where you would like it to go. If you need ideas how to do this, you could look at how the FSBL does it.
