PACKAGE VERSION: Release 1.1



DATE RELEASE NOTES UPDATED:  September 30, 2003



PURPOSE OF RELEASE:   

	The purpose of this release is to demonstrate uClinux running 
	on a ADSP-BF535 Blackfin.  See below for known issues.



COMPONENT/VERSION:


	2.9.3 Binutils & 2.95.3 GCC Toolchains
	- After installing the toolchain rpms see /opt/uClinux/blackfin/bin 
	  for a complete list tool chain executables.  They begin
	  with nisa-elf-*

	2.4.6 Blackfin uClinux kernel 
	- UART 1 is the console.
	- Flat executable support common in uClinux distributions.
	- Ext2 filesystem for the application code.
        
	0.9.15 uClibc -



INSTALLATION INSTRUCTIONS:


	Quick Install Instructions for Blackfin Project.

	1) Install toolchains.
		cd /cdrom/RPMS
		rpm -U nisa-elf-binutils-2.9-6.i586.rpm
		rpm -U nisa-elf-gcc-2.95.3-9.i586.rpm
		export PATH=$PATH:/opt/uClinux/blackfin/bin

	2) Install build environment
	   cd 
	   tar zxvf /cdrom/uClinux-dist-20030919.tar.gz
	   cd uClinux-dist

	3) Build
	   make xconfig or make menuconfig (Save and exit for kernel and user)
	   make dep
	   make

	4) Copy executable to development board
	   cd images/
	   cp linux.dxe /opt/blackfin/linux.dxe

	(Load linux.dxe to development board, set PC register to 1000h, start 
	the kernel).  You should get to a login prompt after the kernel
	boots.  You'll need to enter the following for username and password.

		Username: root
		Password: uClinux



HARDWARE AND SOFTWARE DEPENDENCIES

	- This software has been designed for the ADSP-BF535 from Analog
	  Devices Inc..

	- The Embedded Linux solution on the ADSP-BF535 is has been verified
	  by Metrowerks on the Hawk-35 and Eagle-35 Development boards from 
	  Momentum Data Systems (www.mds.com). (The Eagle-35 has a memory 
	  module installed in U3.)

	- A JTAG emulator or a USB Debug Agent is required to download the 
	  software to the development board. 

	- This software is not intended for use with the Analog Devices 
	  ADSP-21531, ADSP-21532 or ADSP-21533.



SOFTWARE SUPERSEDED:  

	Blackfin Beta 1.0 and Release 1.0



PRODUCT ENHANCEMENTS/FIXED DEFECTS

	Changes since the Beta Release:
		- Fixed tool chain bug that prevented do_initcalls from
		  functioning properly.
		- Fixed login user app bug.
		- Fixed double precision floating point support to not 
		  crash applications.  Converts double to singles, performs
		  operation then converts back to double.
		- Added test documentation.
		- Added .pdf versions of the documentation.
		- Updated system configuration files in vendors subdirectories.
		- Fixed linker bug that was required modification of Makefiles.
		- Found an initialized variable in init.
		- Timer initialization problems caused calibrate_delay_loop to
		  lock up.
		- Cleaned up some unused files.
		- Cleaned up some of the Blakfin include files.
		
	Please note:  There are no plans to support the following items in
	this release:
	- Ethernet networking.
	- Custom bootloader.
	- kgdb - kernel debugger.



KNOWN ISSUES & BUGS

	1) Very few user applications have been tested.  Many of them may not 
	   compile or work.  See the list of tested applications below.  All
	   uClinux user applicationss are included for convience, but you may 
	   need to modify them to get them to work properly.



USER APPLICATIONS TESTED

	- Sash.
	- Busybox.  (Most applications, but no networking)
	- Expand.   Creates a writable partition in RAM.
	- Levee.    A small vi editor.
	- Fileutils.  
	- Shutils.
	- Sysutils.
	- Init.
	- Login.
	- Agetty.
