The Blinky project is an example program for the AT91SAM9261
using Atmel AT91SAM9261-EK Evaluation Board and demonstrating
interrupt usage.

Example functionality:                                                   
 - 2 LEDs blink from DS7 to DS8 and back
 - time of LED switching is determined by Programmable Interrupt 
   Timer (PIT) working in interrupt mode

The Blinky program is available for different targets:
  SAM9261 Int RAM:        configured for on-chip RAM (160kB)
                          (used for target debugging)
  SAM9261 Ext SDRAM:      configured for external SDRAM (64MB)
                          downloaded to external DataFlash (4.125MB)
                          (used for target debugging and production)

Notes: 
  - For "SAM9261 Ext SDRAM" target if Debug is selected the code is 
    loaded to External SDRAM and debugging happens there, if 
    Download to Flash Memory is selected the code downloads to 
    External DataFlash
  - Bootloader has to be downloaded to flash for "SAM9261 Ext SDRAM"
    version to work as standalone. This is done by opening 
    Bootloader project and clicking on "Download to Flash Memory" 
    button.
  - Atmel's Flash Utility AT91-ISP can also be used for downloading 
    binary files to DataFlash

How to start:
  1. Open Bootloader project and click on "Download to Flash Memory"
     button
  2. Select "SAM9261 Ext SDRAM" target in this project and click on 
     "Download to Flash Memory" button
  3. Reset the board
