Overview
========

This README details Altera EPXA1 Development Board specific features of ARMboot. General 
ARMboot information can be found in the README file in the top level install directory.

ARMboot for the epxa1db has been integrated into the Quartus toolflow so that the Altera 
Excalibur Mega-Wizard can be used to configure the Excalibur device. This provides a 
simple GUI based method for configuration of the device parameters (e.g. the physical 
memory map) to match the application requirements.

This use of the Mega-Wizard is intended to ease porting of ARMboot to other boards which 
use Excalibur devices, and to ease porting between different members of the Excalibur 
family.

The Quartus project used for ARMboot can be found in quartus/excalibur.quartus. Details of 
how to modify this project can be found in the online Quartus help. Alternatively you can 
contact Altera support at: support@altera.com.

Installing Quartus
==================

In order to build ARMboot for the EPXA1 Development Board, you must install the Quartus 
tools. The environment variable 'QUARTUS_ROOTDIR' should be set to be the Quartus install 
directory.

The minimum requirement is that you install the makeprogfile utility, which is used to parse 
the Mega-Wizard output:

$QUARTUS_ROOTDIR/bin/makeprogfile

and the Excalibur boot library:

$QUARTUS_ROOTDIR/libraries/software/boot/libboot_xa_ads.a

Building ARMboot for the EPXA1 Development Board
================================================

The following steps should be taken to configure and build ARMboot for the EPXA1 Development 
Board:

1. Configure

    sh# make epxa1db_config
    rm -f include/config.h include/config.mk
    Configuring for epxa1db Board...
    ** See the README in board/epxa1db for build instructions **

2. Build

    sh# make all

Further information can be found in the generic ARMboot README.

Running ARMboot
===============

Having built ARMboot, the generated file, 'armboot.hex', can be programmed into the on board 
flash using the Altera flash programmer:

    sh# exc_flash_programmer -g armboot.hex

Serial output is available through serial connector 'P2', with: baud rate 115200, 8 
bits, 1 stop bit, no parity.
