The Syncing Apple An Exploration of Technology and Devices

OpenEinstein build 48 for Nokia 770

I've complied OpenEinstein 2007-07 build 48. Current as of today. You can download it below. It's about 1.8 megs, bzipped. It will expand into a 16 meg file.

Feel free to download the binary here. You'll need this file also: Einstein.rex. The last thing you need of course is a real Newton ROM, so please have that handy. Directions are in the manual-- it's worth the read if you are going to try and run this.

I'm still trying to figure the best way to make this run on the 770. I like killing the maemo_af_desktop, so that the OpenE isn't locked into it, but sometimes OpenE won't start. If someone has it going full screen on the 770, please add a comment for your exact startup line. I still haven't gotten it to go the full 800x480 on the 770.

iPhone vs N800 Quick Comparison

Apple iPhone: ARM CPU @ 667mhz [Samsung], 128Mb ram, 8GB Flash
Nokia N800: ARM CPU @ 320mhz [TI], 128Mb ram, 256Mb Flash

N800 has dual SD cards for more Flash, iPhone has no way to extend the 8Gb. N800 has a bigger screen, higher DPI but doesn't have the light-touch touch-screen like the iPhone. I'd still consider getting a N800 to replace my 770 if the price drops. I'd like to use ITOS2007 and have Flash 9 available for browsing-- especially now since Mozilla has just been released for ITOS2007. We'll probally never see Flash in the iPhone, but who knows. I just don't think Apple will do it.

Building Open Einstein

Here are some more detailed instructions on getting Open Einstein built on MacOSX Intel, using the JAM complier and targeting the Nokia 770. I also built it for MacOSX, to run locally on my macbook.

The published directions are here, and you should read them first and familiarize yourself with them.

Install MacPorts

* MacPorts-1.5.0-10.4.dmg

Open a terminal and then use macports to install the following packages:

$ sudo port install gettext
$ sudo port installlibffi
$ sudo port install jam
$ sudo port install arm-none-linux-gnueabi-gcc

Then you must add

/opt/local/bin

to your $PATH on the Mac (edit .bash_login in your home directory), then restart your terminal or read in the new bash_profile.

Pull down Klibs and Build

K is located at SourceForge (http://sourceforge.net/projects/KLibs/)

$ cvs -d:pserver:anonymous@klibs.cvs.sourceforge.net:/cvsroot/klibs login
[Enter] for password

$ cvs -z3 -d:pserver:anonymous@klibs.cvs.sourceforge.net:/cvsroot/klibs co -P K

$ cd $PATH_TO_KLibs/_Build_/Jam

$ jam -starget=nokia2006

Klibs should build with out problems. If you want to build for the Mac, just leave off the -starget parameter.

Pull down Open Einstein and Build

$ svn checkout http://einstein.googlecode.com/svn/trunk/ einstein

$ cd einstein/Einstein/_Build_/Jam

$ jam -sK=$PATH_TO_KLibs -starget=nokia2006 -sjittarget=GENERIC

Now there is a new folder in the /_Build_/Jam directory called build.ARM-LINUX-Nokia2006. This folder will contain the einstein binary for the Nokia 770.

Move files over to 770

You need three files:

[You should set up sshd on 770, change password of 'user' to something you know, change the ip address below to match your 770 local ip. Use ifconfig -a to check the local 770 ip.]

Now copy the files:

$ scp $PATH_TO_EINSTEIN/_Build_/Jam/build.ARM-LINUX-Nokia2006/einstein user@192.168.155.155:
$ scp $PATH_TO_EINSTEIN/_Data_/Einstein.rex user@192.168.155.155:
$ scp $NEWTON_ROM user@192.168.155.155:

Once they are copied over, you can start Open Einstein like this:

/home/user # ./einstein -l log2 -m 737041 .
Welcome to Einstein console.
This is Einstein Platform 2007.
Creating image...

And you should see the Newton Start up on your device. Below is a screen shot of the Newton running on my MacBook, in Xwindows:

Open Einstein booting on 770

After some trial and error, and some help from Paul G, I managed to build Open Einstein for both my Intel Mac and for my Nokia 770, using just my Macbook. I followed the directions to build at the Google Code site. I'll have more explicit directions soon, but the code does build and run on the 770. And you don't need scratchbox to build it! Excellent work Paul.

Here are some screen shots (click for bigger versions):

After Einstein was built, the directions for starting it are the same as before. The easiest way to control einstein is via SSH into the 770, so that you can shutdown all the Hildon interfaces.

Full directions to build this will be up soon.

Update: There is a new Einstein Platform 2007.7 User Manual at Paul's Einstein Page.

Einstein on 770 mini-update

For those of you interested in the Einstein Project (emulation of an Apple Message Pad 2000 on your Nokia 770), I have some news. Good and bad of course.

The Good news: Paul has his own 770, which was donated to him. This will certainly help the eventual development of Einstein on the Nokia platform.

The Bad news: Paul is very busy working on his dissertation, so work on Einstein is paused.

Below is his reply to me (posted with permission):

Hello Andrew,
There is no progress regarding Einstein so far. I am currently very busy with writing my dissertation.
I know it's currently too slow to be usable.
Regards,
Paul

Booting Einstein on the 770

After a fews days of experimentation, I have a workable recipe for using Einstein with the 770. There is work that remains to be done to Einstein, but it does run, just slowly and it is buggy. This is not ready to be a production Newton yet.

First there are some things I'm assuming you have already done:

• have root enabled
• have either SSH over wifi, BT or USBnet
• have a Newton ROM
• have the Einstein package for 770

First, move the einstein package and the ROM over to your 770. You need to run it from the built-in memory, unless you have your flash card partitioned and mounted as a ext2- if so, it will run fine from there.

You don't have to have any swap enabled, it runs the same with or without it.

You will be ssh'ing into the 770 then running the script below which kills OSS/Maemo/Hildon to free up ram, then finally run Einstein.

The script was provided by Simon Budig (Nomis on #Maemo) who was kind enough to share it with me. I was first killing processes by hand, using the kill command- but in order to do this you must enable the --set-rd-flags=no-lifeguard-reset with the flasher to avoid having the 770 reboot as you kill 'critical' processes. Using the script below, and stopping them via the init scripts is the proper way to do this.

Once Einstein is running you type 'power' to power it on. It should take about three minutes to start up the first time. After awhile it gets flakey and may disappear from the screen- use the power command once to power it back on.

Note: Run einstein as root!

Nomis' Script- for USB networking
(this will kill any wifi session- see my modification below if you are using ssh over wifi)

/etc/init.d/x-server.sh start

/einstein --machine=737041 .

My slightly modified script for SSH via wifi:

#!/bin/sh

export PATH="$PATH:/sbin:/usr/sbin"
/etc/init.d/ttyusb0 stop
/etc/init.d/lessertunjo0 stop
/etc/init.d/osso-ias stop
/etc/init.d/af-base-apps stop
/etc/init.d/btname stop
/etc/init.d/af-startup stop
/etc/init.d/maemo-launcher stop
#/etc/init.d/osso-ic stop
#/etc/init.d/wlancond stop
/etc/init.d/btcond stop
/etc/init.d/osso-systemui stop
/etc/init.d/esd stop
/etc/init.d/osso-hss stop
/etc/init.d/bme-dbus-proxy stop

/etc/init.d/x-server.sh stop
/etc/init.d/mce stop
/etc/init.d/dbus-1 stop
/etc/init.d/dnsmasq stop
/etc/init.d/ppp stop

/etc/init.d/x-server.sh start

export DISPLAY=":0.0"
echo 'done'

I like to start mine by hand. So after the script is run i type:

Nokia770-51:/home/user/newton# ./einstein --machine=737041 .
Welcome to Einstein console.
This is Einstein Platform Preview 1.

and after a few minutes you should see the Newton booting on the screen.

A new Era Dawns

NewtOS/Einstein works on the 770!

This is developing, but it works at this point, once you disable the kernel-watchdog and kill Matchbox to free up enough RAM for Einstein to launch. I'll post a more detailed receipe of what I did later today, when I get some free time.

Photos of Newton Booting on Nokia 770

Paul has put up the Einstein Platform 2006 ( for Nokia 770) on his site.

Don't forget that you'll need a Newton ROM to make this work. Paul has a Newton Emulator for the Mac (on that same page) that has a special application that will dump a Newton ROM over the network to your Macintosh. Using a MP2100 ROM is the best idea.
