Meego + NITDroid + Meamo + power kernel + uboot on two SD cards - my way - work in progress!

Before you begin, make sure that the battery is fully charged. Make sure that you can make a reflash your device.


You need:
- N900.
- Clear pr1.3.
- Rootsh installed.
- SD card 1GB - NITDroid - 256MB or 512MB should work. But 128MB not!.
- SD card 2BG - meego.

Installing NITDroid:

1. Run Application Manager and activate Fremantle Extras, Extras Testing and Extras-devel - how to in maemo wiki. Wait for refreshing the directories. Close the Application Manager.

2. Insert the SD card (minimum 1GB) - all data will be removed from the card.
3. Run x-terminal (ctrl + shift + x) and enter:

Answer "YES" to the question and wait. It would take 30-45 minutes.
The installer downloads the necessary data and saves it in the directory:
Will be installed the necessary applications and kernel. Android system will be installed on the memory card. Entries will be added to the multiboot menu.

After installation You should have something like:
4. Shutdown device
5. Power on device with slide open
keys "q" (1) and "p"(0) should boot maemo with 2.6.28-omap1 kernel
key "w" (2) should boot Android with 2.6.28.NIT.06 kernel
6. Test
Do not reeboot device! Shutdown it and power on - sometimes reeboot causes problems.
Always do full boot - shutdown device in PIN entry (maemo) - do not flash and set up kernel corectly.

Installing kernel-power 47
1. Connect to internet
2. Run x-terminal (ctrl + shift + x) and enter:
After installation You should have something like:
3. Shutdown device
4. Power on device with slide open
5. Test

Installing Meego:

On PC
1. Go to "http://tablets-dev.nokia.com/meego-codedrop.php"
2. Enter Your IMEI and click send.
3. Accept the terms of the License Agreement.
4. Download "meego-handset-armv7l-n900-final-mod-1.1.0.0.20101101.3-mmcblk0p.raw.bz2" and unpack.
5. Format the SD card with Fat32.
6. Connect N900 to PC in data storage mode.
7. Go to N900 (not to SD) and create catalogue meego.
8. Copy raw image "meego-handset-armv7l-n900-final-mod-1.1.0.0.20101101.3-mmcblk0p.raw" to meego (/home/user/MyDocs/meego)
9. Disconnect device.
10. Insert SD Card - all data will be removed from the card.
On N900
11. Run x-terminal (ctrl + shift + x) and enter:



Installing uboot-pr13

1. Connect to internet
2. Run x-terminal (ctrl + shift + x) and enter:
3. Shutdown device
4. Power on device with slide open
5. Test

In uboot press any key to abotr.
Start Meego with:
- wait for shutdown, power on and wait
Start Maemo with:
- wait for shutdown, power on and wait

Booting NIT is imposible after booting Megoo and vice versa
Always beetwean NIT and meego full boot maemo with 2.6.28-omap1 (not only to PIN entry)
Always have correct SD card inside and closed cover.

Enjoy

<------------------------ Edit 2011.05.18 ------------------------>
Problems:
1. Incorrect software version displayed in maemo
a) In the Phone application, enter "* #0000#
b) Go to System-> About
This procedure displays the version of the "<unknown"
To Fix it:
- Connect to the Internet
- Run x-terminal (ctrl + shift + x) and enter:

OC in Android

I think so.
1. Start maemo.
2. Insert the SD card from NITDroid.
3. Run x-terminal (ctrl + shift + x) and enter:
Test

Installing 2'nd NITDroid on the eMMC

The operation probably a step more dangerous than previous ones.

Plan:
- Make a copy of "/ home / user / MyDocs"
- Make a copy of "/ home"
- Re-partitioned eMMC,
- Restoration of copies,
- Installation NITDroid.

Description will not be included (so far) detailed information. I do not have time today to describe the exact steps.


A copy of the "/home/user/MyDocs" - the folder visible when you connect your phone to your computer.
1. Connect your phone to PC and copy the data on your computer HDD.
2. After copying the data disconnect the phone and go to make a copy of "/home".
A copy of the "/home" - a copy of the message, and other settings.
1. Switch the phone to Offline mode or remove the SIM card - just for safety.
2. Run x-terminal.

root
umount "/home/user /MyDocs"

I will give details later

unmount all "/opt/ *" and "/opt/"
If "umount /opt/ *" does not work to use with the "-l"
("umount -l /opt/ *")
Copy all the data on SD card (formatted to ext2 or ext3, not FAT).
Or mount "/dev/mmcblk0p1" (MyDocs) somewhere outside of /home/" and unmount "/ home" (and "/home/user /MyDocs")

use:
example:
mkdir /somedir
mount /dev/mmcblk0p1 /somedir
"dd if = /dev/mmcblk0p2 of = /somedir/mmcblk0p2.raw"
unmount "/somedir"



Restart the phone
Connect to PC
Do copy of mmcblk0p2.raw to the PC.
Disconnect.

Umount /opt/* & /opt/ & MyDocs & /home

Use the "sfdisk" to repartitioning eMMC.
in case of problems to force-f

"Sfdisk-f / dev/mmcblk0"
p1 mydocs fat32
p2 linux home
p3 swap
p4 linux

Example:
root
sfdisk-f / dev/mmcblk0
0 753792 c
7573792 131072 83
24576 82 884864
67584 83 909440
y

will be created
p1 - ​​23GB FAT32 Win
p2 - 3.9GB Linux
p3 - 756MB Swap
p4 - 2GB Linux


After re-part reboot phone and format the partitions

p4 format as follows:
"mke2fs-L NITDroid-j-m0 / dev/mmcblk0p4"

Restore the data.

mount / dev/mmcblk0p4:
"mount-o noatime, rw / dev/mmcblk0p4 / and"
unpack the file system partitions Android
example:
cd / and
tar xvf / home/user/MyDocs/android/N12_UMay.tar

extract the kernel and move it to partition p4:
example:
cd /home/user/MyDocs/android/kernel
dpkg-X nitdroid-kernel-2.6.28-06_final1_armel.deb ex
ex cd
cp -rf * /

add items to multiboot
cd /etc/multiboot.d
cp 11-NitDroid- mmcblk1p2-2.6.28.NIT.06.item 12-NitDroid- mmcblk0p4-2.6.28.NIT.06.item
vi 12-NitDroid- mmcblk0p4-2.6.28.NIT.06.item

in the first line change the mmcblk1p2 -> mmcblk0p4
in the fourth line change $ {EXT_CARD)p2 -> mmcblk0p4
NO ${INT_CARD}p4 or / dev/mmcblk0p4
open back cover to run NIT from mmcblk0

seems possible...anyone giving this a try...i don't have another memory card to try this out.

Also just setup my N900 with NITDroid N12 after a full flash of rootfs & EMMC so don't want to start all over again unless it is worth it...

will try it tomorrow

this actually works ! just need to test the image, but usiing uboot and different kernels works !

One "bug" in your tutorial I noticed I will try that later, but with one repartitioned SD card

hum in fact, I always get a kernel panic... vfs can't sync and mount root fs with daily image of yesterday... also, I noticed that it says that it cannot read boot.scr even if I created it (but with leafpad)
help ?

oh and for the one willing to know, writing daily image with n900 is veeeeeryyyy slow... around 3 or 4 hours ! so prefer the win32 disk imager to do that lol

edit: i still have the can't read boot.scr message but now daily image of today seems booting... wait and see

edit: it works ! ui seems faster than before, but still as I don't have a very good micro sd card ... lol photos are taken but seems gray ?! lol

thanks zazun..

i finally got triple boot...

1. Maemo
2. Kernel Power 47
3. Meego 1.2 Developer Edition
4. NITDroid N12

can you overclock in android with this ??? please thank you

Wow, this is amazing work zazun! Gratz on your guide! Unfortunately I do not have a USB port on my N900 anymore so I cannot try it out... but still is great work!

I do have a little question, out of curiosity, how come nobody seems to be able to dual or triple boot from the eMMC? Aren't we able to partition the 32gb to show up as multiple drives and install the different OS onto them?

yes of course

personally i've got :

1. Maemo omap1
2. Maemo kernel-power v47
3. NITDroid N12
4. Maemo omap with uBoot
5. Maemo kernel-power v46 with wifi bleeding edge drivers

edit : because install on eMMC is dangerous... you'll need to repartition it and it could corrup your system =S
