DESCRIPTION
===========
This is a small boot program for the Cirrus Logic CDB89712 evaluation
board.
The program initializes the system and memory registers, the MMU is setup
and a small C function is called that blinks the LED on the board.


COMPATIBILITY
=============
The project is compatible with the Cirrus Logic CDB89712 board.

GETTING STARTED
===============
Start the IAR Embedded Workbench for ARM.
Select File->Open->Workspace...
Open the workspace file
...\IAR Systems\Embedded Workbench 4.0\ARM\src\examples\Cirrus\cdb89712\cdb89712.eww

The default setup builds the application and generates an output file
in the mpds-code linker output format.

To download the program into flash, use the flash downloader download.exe
from Cirrus Logic:
  download debug\exe\cdb89712.tsk
Details on how to prepare the board for flash download are found in the
board documentation.

Debugging with a JTAG interface is also possible. The CPU must be
running for this to work, debugging in standby won't work.

CONFIGURATION
=============
The project uses a modified version of cstartup (cdb89712_cstartup.s79). The
difference from the standard cstartup is the added code to perform the
CS89712 and MMU setup.
