Basic SD Card Project 1.4
Purpose
This application performs several read & write tests on a Secure Digital (SD)
card inserted into the evaluation kit.
Hardware Requirements
This package can be used with the following Atmel evaluation kits:
- AT91SAM9260-EK
- AT91SAM9261-EK
- AT91SAM9263-EK
- AT91SAM9RL-EK
- AT91SAM9XE-EK
- AT91SAM9G20-EK
- AT91CAP9-DK
- AT91CAP9-STK
Description
When launched, the example will wait for a SD card to be connected, if the
evaluation board supports this feature (i.e. a PIO is connected for that).
Once the card is connected, it is initialized and then several read/write tests
are performed on it.
Usage
-
Compile the application.
-
Connect the DBGU port of the evaluation board to the computer and open it
in a terminal. Debug information output by the device will be visible that
way.
- Settings: 115200 bauds, 8 bits, 1 stop bit, no parity, no flow control.
-
Download the program inside the evaluation board and run it. 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.
-
Upon startup, the application will output the following lines on the DBGU:
-- Basic SD-Card Project 1.4 --
-I- Please connect a SD card ...
-
As soon as a SD card is connected, the tests will start. Please note that
testing the whole device may take a very long time, depending on its size.
