Purpose
The Basic-sdcard-project will help you to get familiar with sdmmc_mci interface on AT91SAM microcontrollers. It can also help you to get familiar with the SD operation flow which can be used for fast implementation of your own sd drivers and other applications related.

You can find following information depends on your needs:

Requirements
This package can be used with all Atmel evaluation kits that have MCI interface, the package runs at SRAM or SDRAM, so EBI interface and SDRAM device is needed if you want to run this package in SDRAM

Description
Open HyperTerminal before running this program, use SAM-BA to download this program to SRAM or SDRAM, make the program run, the HyperTerminal will give out the test results.

Usage
  1. Build the program and download it inside the evaluation board. Please refer to the SAM-BA User Guide, the GNU-Based Software Development application note or to the IAR EWARM User Guide, depending on your chosen solution.
  2. On the computer, open and configure a terminal application (e.g. HyperTerminal on Microsoft Windows) with these settings:
    • 115200 bauds
    • 8 bits of data
    • No parity
    • 1 stop bit
    • No flow control
  3. Start the application
  4. In HyperTerminal, it will show something like
    -- Basic SD-Card MCI Mode Project xxx --
    -- AT91xxxxxx-xx
    -- Compiled: xxx xx xxxx xx:xx:xx --
    -I- Please connect a SD card ...
    -I- SD card connection detected
    -I- Cannot check if SD card is write-protected
    -I- SD/MMC card initialization successful
    -I- Card size: *** MB
    -I- Block size: *** Bytes
    -I- Testing block [  *** -   ***] ..."
