Pan1nx: /* Write CE to device */ Clarify the point about moslo exporting the partition as drive to the host PC

= MeeGo 1.3 Community Edition installation for N950 =

(Basic information as copied from https://meego.com/community/device-program/devices/nokia-n9-devkit)

The Nokia N950 is a platform available now for developers targeting the Nokia N9 and MeeGo handset apps in general. Technical details are available at http://developer.nokia.com/swipe. Questions & comments: http://forum.meego.com/showthread.php?t=3597.

IMPORTANT: commercial developers are encouraged to apply directly at http://developer.nokia.com - thank you for your understanding.

== How to use Community Edition on N950 ==

Assumption: you have N950 device with working Harmattan setup. You should also have the skills required, similar to what is required for using N900 CE: http://wiki.meego.com/ARM/N900/GettingStarted.

'''The procedures described here will void any warranty (if there was any), and will destroy your Harmattan setup, losing any data you have there.''' However, you can always go back to a fresh Harmattan installation with the OneClickFlasher package available at: http://www.developer.nokia.com/info/sw.nokia.com/id/db230178-aa63-4c73-ba7f-20930da13cad/Nokia_N950_OneClickFlashers.html

=== Downloading the MeeGo Community Edition release ===

=== Flasher for N950 ===
Download Harmattan flasher from [http://tablets-dev.nokia.com/maemo-dev-env-downloads.php here].

Before you proceed make sure that "Device lock" is not enabled in Harmattan (In Settings \ Security \ Device Lock \ Autolock: off). If you have an Mail-for-Exchange account configured, you may need to delete it before you can disable device lock.

If flasher bombs out with "Devicelock ON: cannot flash unsigned image", then you didn't, go back and disable it.

If the beta2 flasher errors with "bb5_rdc_cert_read" or [http://www.martindengler.com/proj/n950-flasher-beta1#failure a few other errors], try the [http://www.martindengler.com/proj/n950-flasher-beta1 beta1 flasher].

=== MeeGo Bootloader (Moslo) ===

In order to boot MeeGo on N950, the default OS, Harmattan, must be replaced with MOSLO, the Meego OS LOader.
Moslo can be flashed as a fiasco image, available at: http://TBD (source: https://gitorious.org/meego-developer-edition-for-n900/moslo)

* IMPORTANT: before installing Moslo, boot into Harmattan at least once and wait for a few minutes.
* Power off the device, disconnect usb or changer.
* Run flasher:
sudo flasher -F <moslo-image.bin> -f
Flasher now waits for a device to connect.
* Connect your N950 and wait for flashing to finish.
* Do not disconnect. Read on.

=== Write CE to device ===

After flashing MOSLO, boot the device by disconnecting and re-connecting the USB cable to the PC. You will see a warning and a disclaimer screen for 10 seconds followed by green text based MOSLO welcome screen. Wait for the text "Rootfs now exported via USB".

If you don't get the MOSLO screen after successfully flashing MOSLO, then let the device finish booting into harmattan and reboot it. It can take several full reboots of the device to fully enable MOSLO.

If you have automount enabled in your Linux system, the device may appear as a normal USB drive to your desktop. Automount may not show the drive at first because it is in vfat format. Automount will typically use volume ID as mountpoint name.

IMPORTANT: On some systems (Ubuntu) automounting may have too restrictive options. Manual mounting is recommended.

IMPORTANT: Although the '''drive exported by device via MOSLO to the host PC it appears as /dev/sdX, inside the device it is a partition''', instead of a full drive.

At first MOSLO connection, the partition has to be reformatted. Make sure it is unmounted:
sudo umount /dev/sdX
sudo mkfs.ext4 /dev/sdX
You will see warning: "/dev/sdX is entire device, not just one partition! Proceed anyway? (y,n)". This is expected. Just make sure you got the right device node and say "y".

For mounting the MeeGo rootfs manually:
sudo mkdir -p /media/<choose mountpoint name for your N950>
sudo mount /dev/sdX /media/<mountpoint of your N950>

If you already had an MeeGo image on the partition, it can be erased by running:
sudo rm -rf /media/<mountpoint of your N950>/*

Extract the Community Edition .tar.bz2 to the mounted rootfs partition with:
sudo tar --numeric-owner -xf <path>/<CE_package>.tar.bz2 -C /media/<mountpoint of your N950>

After the extraction is ready, unmount/remove safely/eject the partition before disconnecting from usb:
sudo umount /media/<mountpoint of your N950>

=== Boot to CE ===

* The device should start booting to MeeGo right after disconnecting the USB.
* Otherwise start normally by hosding power hoy for 2-4 seconds.
* First you should see the disclaimer screen.
* Next you see a green-on-black Moslo bootscreen.
* The last line should say: "Running Meego Kernel" (it is shown very briefly)
* Then wait patiently for desktop to come up.

Shutting down is done simply by holding the power key until either a shut down graphic or a red screen is shown.
Check that screen back light goes out. If device does not react, hold the power key for over 8 seconds.
This will force HW shut down. Note: using forceful shut down might corrupt the filesystem, leading to a non-bootable setup.

====Trouble starting?====

If device does not react, hold the power key for over 8 seconds.

In case battery is very low, the screen may stay black even if booting continues.
* Connect usb or charger and let Moslo charge the battery at least for a few minutes.
* Then disconnect usb/charger and device should continue booting to MeeGo.
* You can reconnect usb/charger after a few seconds. Latest at the Meego splash screen.

Don't panic - try again, check the steps and finally ask for advice at #meego-arm IRC channel.

=== How to remove MeeGo/Moslo and restore Harmattan ===
In order to boot Harmattan again, MeeGo and Moslo must be removed.
This can be done by using OneClickFlasher available here:
http://www.developer.nokia.com/info/sw.nokia.com/id/db230178-aa63-4c73-ba7f-20930da13cad/Nokia_N950_OneClickFlashers.html

Running the OneClickFlasher will overwrite MeeGo/Moslo with Harmattan. All personal settings will be lost.
It will take about 15-30 minutes.

== Open issues ==

* How about dual boot with Harmattan?
** Not possible, at least right now. There might be ways, with either Moslo or some other eg. u-boot.
* Will this work in N9?
** Yes, but not yet. Some details (like how to restore Harmattan) to be worked out still. If you have N9 wait until suitable moslo for N9 has been released.

=== Reporting bugs against Community Edition ===

* File a bug report on [http://bugs.meego.com/ bugs.meego.com]
* Use '''[CE]''' in the summary
* Add the '''N950''' and '''N900CE''' keywords to the bug report
* Select from Platform '''N900''', if bug can be reproduced with N900 also.

*Notice:
** If bug is producible with MeeGo image also, remove the [CE] prefix from the summary. It's used only for the Community Edition specific bugs.
** Feel free to suggest MeeGo_N900CE_Release_Blocker.
** '''If bug is for application''', check if there's a '''upstream link''' for direct reporting in [[/AppsInCE | CE application list]]. If there's a link, please report to upstream, if not, then to the MeeGo Bugzilla.
** If you found a bug when using MeeGo 1.2 '''Harmattan''', please file the bug to the [http://www.developer.nokia.com/bugs/ http://www.developer.nokia.com/bugs/]

Pan1nx: /* Boot back to Harmattan */

= Nokia N9 Devkit (N950) instructions =

(Basic information as copied from https://meego.com/community/device-program/devices/nokia-n9-devkit)

The Nokia N950 is a platform available now for developers targeting the Nokia N9 and MeeGo handset apps in general. Technical details are available at http://developer.nokia.com/swipe. Questions & comments: http://forum.meego.com/showthread.php?t=3597. IMPORTANT: commercial developers are encouraged to apply directly at http://developer.nokia.com - thank you for your understanding.

== Open issues ==

List the open issues here, preventing the release of CE for N950.

* What about N9? A: No solution yet, working on it.

== How to use Community Edition on N950 ==

Assumption: you have N950 device with working Harmattan setup. You should also have the skills required, similar to required by using N900 CE: http://wiki.meego.com/ARM/N900/GettingStarted.

'''The procedures described here will void any warranty (if there was any), and can very likely detroy your Harmattan setup, loosing any data you have there.''' However, that is not the intention and the procedure here should result in a working "dual-boot" configuration and should not affect your Harmattan installation.

=== Download release ===

Coming.

=== Flash MOSLO ===

Where to get Flasher?
TBD soon
Where to get MOSLO.bin?
TBD soon

=== Write CE to device ===

After flashing MOSLO, boot device by disconnecting and re-connecting USB cable to PC. When MOSLO starts, you will get a welcome screen and some messages about making MeeGo partitions. Wait for the text "Rootfs now exported via USB". Your device should be now visible in PC as USB drive. Write the CE .tar.gz to the mounted device with eg.
cd /media/<mountpoint of your N950>
gunzip -c <path>/<CE_package>.tar.gz | sudo tar xf -

=== Boot to CE ===

After previous step, device should start booting to MeeGo right away after disconnecting the USB cable.

=== Boot back to Harmattan ===

While powering on, press volume down HW key until you see the disclaimer and the device will restart (disclaimer is showing for 20 seconds). Device will reboot to Harmattan after that (it will load MOSLO and reboot to Harmattan).

=== How to remove MeeGo ===

Connect USB cable while device is powered off, to see the text "Rootfs now exported via USB". In your PC issue do the following:
echo YES | sudo tee /media/<mountpoint of your N950>/remove-meego

or directly in device shell once booted to MeeGo (as root):
echo YES /remove-meego

After that, restart the device and moslo will self-destruct (including erase itself from NAND and resize back the content partition). You will now have Harmattan only setup.
