-
This page serves the purpose of assembling a complete and current howto-guide for the perfect N900 setup.  
+
Since the [[N900]] has been release many developments have been made by the community. This page is to provide a generic guide to getting started with good foundations.
-
The initial information here is based on my personal experience and the rich trove of experience which is talk.maemo.org.
+
This page will mainly link all the useful bits of the wiki and other useful information together.

+
One of the most common issues with the [[N900]] is the surface mounted USB port.
 +
If you are not careful with it, the port can be ripped from the PCB.
 +
Due to the design of the port if this occurs, it can be vary difficult to repair successfully.
-
[http://talk.maemo.org/showthread.php?t=65568 N900 battery options]
+
Therefore it is highly recommend to reinforce your USB port by soldering the casing of the USB to the PCB. Information on this is covered in great extent on talk.maemo.org

/* TODO: USB pre-broken fix */
+
Another common modification is to remove the locking pins on all your microUSB cable connectors. This can be done by filing them down carefully with a small file.
-
[http://talk.maemo.org/showthread.php?t=75920]
+
The latter is important, especially if you don't feel confident in taking your N900 apart to reinforce the port.

Download the firmware flasher:

So you have your [N900]
-
[http://skeiron.org/tablets-dev/maemo-dev-env-downloads/ Flasher & SDK Downloads]
+
The first step especially if it's used is to flash the firmware.
 +
This can be used to clean off any unstable software and make a clean start.
-
Download the latest official Nokia Firmware Images for your N900:

== Flashing the device ==
+
It's recommended to download the latest Nokia firmware images for your region.
-
The following flashing procedure has proven the most stable to me:
+
The latest versions are highlighted.
-
{{warning}}Always use a fully charged battery!
+
[http://wiki.maemo.org/Updating_the_tablet_firmware#N900 Firmware Flashing]
-
* Turn your device off, disconnect USB
+
==Highly Recommended Further Setup==
-
* (As root) flash the FIASCO firmware image:
+
-
  flasher-3.5 -F RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin -f
+
-
* When you get "No suitable USB device found" connect your N900 through USB.
+
-
* Wait for the flashing to finish.
+
-
{{warning}} Don't reboot
+
-
* Flash original eMMC image:
+
===Importance of CSSU===
-
  flasher-3.5 -F RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin -f
+
-
* Wait for the flashing to finish.
+
-
* Reboot the device by _reinserting_ the battery
+
-
Upon first login, enter your locale settings (Timezone, local time, etc.).
+
If you have flashed your firmware as above, your [N900] will now be on the last major Nokia release (PR1.3). From here onwards the Maemo Community are providing vital security updates, fixing bugs and generally moving the device forward. This is known as CSSU or Community SSU.
-
Run latest official Nokia SSU (upgrades your device firmware to V1.3.1) by launching App manager / Update from the applications menu.
+
It is recommended all users install [[CSSU]], of which there are two versions.
-
== Getting root access ==
+
More information on this is [http://wiki.maemo.org/CSSU here]
-
[http://wiki.maemo.org/Root_access 1001 ways of becoming root]
+
-
* Add the Extras-Testing repository to the Hildon Application Managers catalog
+
==Recommended Further Setup==
-
  name: Maemo extras-testing
+
-
  uri: deb http://skeiron.org/repo/repository.maemo.org/extras-testing/ fremantle free non-free
+
-
  dist: fremantle
+
-
  components: free non-free
+
-
* Add the Extras-Devel repository as well
+
===Kernel Power===

+
-
  uri: http://extras-devel.merlin1991.at/ fremantle free non-free
+
-
  dist: fremantle
+
-
  components: free non-free
+
-
* Disable OVI repository (conflicts with CSSU)
+
[[Kernel Power]] is a community developed Kernel that provides addition features and fixes to the Kernel. [[Kernel Power]] also provides the ability to overclock the device with an additional package '''kernel-power-settings'''
-
* Wait for repository update to finish (Hildon Application Manager is slooow) and install 'rootsh' from the system section.
+
While overclocking is not recommended and has been known to reduce the lifetime of the device, the [Kernel Power] package on it's own is recommended and will not alter your device from the standard 250Mhz-600Mhz clock speed.
-
* To get remote access over the network (way more comfy) install SSH server by launching XTerminal from the application menu and running:
+
It provided important features like stable [[Smartreflex]] which will significantly increase battery life.
-
  sudo gainroot
+
-
  apt-get install openssh
+
-
You will be asked for your new root password.
+
-
/*TODO: Change PW hash to enable passwords > 8 chars */
+
-
* Finally launch xterm and run
+
More information on this is [http://wiki.maemo.org/Kernel_Power here]
-
  ifconfig wlan0
+
Please note Kernel Power page is heavily biased on overclocking and is provided for further reference only.
-
* Write down the IP address - from now on you can use the SSH client of your choice to connect to your favorite pocket computer - enjoy!
+
===Utilise the SD Card===
-
= Upgrade to CSSU-thumb =
+
The [[N900]] has a uSD card slot, it's a good to use this as much as possible to reduce flash wear from the devices eMMC.
-
[http://wiki.maemo.org/CSSU What's CSSU?]
+
-
[http://talk.maemo.org/showthread.php?t=84829 What's thumb2 ISA?]
+
Many users setup there swap space(s) on the uSD card this frees up the I/O of the device.
-
{{info}} cssu-thumb contains a kernel based on kp51r1, therefore you automatically benefit from all kernel-power features (undervolting, overclocking, framebuffer, ...). See [http://wiki.maemo.org/Kernel_Power Kernel Power Wiki] and [http://talk.maemo.org/showthread.php?t=85665 Kernel Power 51r1 on tmo]
+
There has been much discussion on this and applications written to help with this.
-
== Repositories ==
+

-
Disable extras-testing - it will be replaced by its thump-compiled counterpart from the CSSU repository. Make sure Nokia and Maemo Extras repositories are enabled though.

Swappolube is a package to modify memory management.
 +
Most users tweak this to suit there device and usage.

Introduction

Since the N900 has been release many developments have been made by the community. This page is to provide a generic guide to getting started with good foundations. This page will mainly link all the useful bits of the wiki and other useful information together.

Hardware

Hardware Accessories

Information on all recommended hardware accessories is here.

Hardware Specifications

Information on the specs can be found here

Recommended Hardware Modifications

One of the most common issues with the N900 is the surface mounted USB port. If you are not careful with it, the port can be ripped from the PCB. Due to the design of the port if this occurs, it can be vary difficult to repair successfully.

Therefore it is highly recommend to reinforce your USB port by soldering the casing of the USB to the PCB. Information on this is covered in great extent on talk.maemo.org

talk.maemo.org Fixing USB Thread

Another common modification is to remove the locking pins on all your microUSB cable connectors. This can be done by filing them down carefully with a small file.

The latter is important, especially if you don't feel confident in taking your N900 apart to reinforce the port.

File System

File System information

Firmware

Initial Firmware Setup

So you have your [N900] The first step especially if it's used is to flash the firmware. This can be used to clean off any unstable software and make a clean start.


It's recommended to download the latest Nokia firmware images for your region. The latest versions are highlighted.

Firmware Flashing

Highly Recommended Further Setup

Importance of CSSU

If you have flashed your firmware as above, your [N900] will now be on the last major Nokia release (PR1.3). From here onwards the Maemo Community are providing vital security updates, fixing bugs and generally moving the device forward. This is known as CSSU or Community SSU.

It is recommended all users install CSSU, of which there are two versions.

More information on this is here

Recommended Further Setup

Kernel Power

Kernel Power is a community developed Kernel that provides addition features and fixes to the Kernel. Kernel Power also provides the ability to overclock the device with an additional package kernel-power-settings

While overclocking is not recommended and has been known to reduce the lifetime of the device, the [Kernel Power] package on it's own is recommended and will not alter your device from the standard 250Mhz-600Mhz clock speed.

It provided important features like stable Smartreflex which will significantly increase battery life.

More information on this is here Please note Kernel Power page is heavily biased on overclocking and is provided for further reference only.

Utilise the SD Card

The N900 has a uSD card slot, it's a good to use this as much as possible to reduce flash wear from the devices eMMC.

Many users setup there swap space(s) on the uSD card this frees up the I/O of the device.

There has been much discussion on this and applications written to help with this.
