Many applications use a large external storage device, such as an SD Card or CF card to store data.
The DE2-115 board provides the hardware and software needed for SD Card access. In this
demonstration we will show how to browse files stored in the root directory of an SD Card and how
to read the file contents of a specific file. The SD Card is required to be formatted as FAT File
System in advance. Long file name is supported in this demonstration.
Figure 6-9 shows the hardware system block diagram of this demonstration. The system requires a
50MHz clock provided by the board. The PLL generates a 100MHz clock for the Nios II processor
and other controllers. Four PIO pins are connected to the SD Card socket. SD 4-bit Mode is used to
access the SD Card hardware. The SD 4-bit protocol and FAT File System function are all
implemented by Nios II software. The software is stored in the on-chip memory.
