SD card interface

Hi, I want to add a SD card reader to the hardware of a cyclone3. I have the JTAG/ISP SPI interface wired out. If the system is booted from flash, can I bolt a SD card reader to the programme...

FlashNCE and data pins are dual purpose pins and they can indeed be used as GP I/O pins.

You have to set them as generic I/O in the device configuration assignments

Ok, so you would program those with the file?
