maemo.org - Talk - Meego, NITDroid, Meamo, power kernel, uboot 2SD cards - my way

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:

Code:

        

# Get the root access

root



# To ensure that applications catalogs are refreshed

apt-get update



# Install nitdroid-installer. Answer "Y" to the question and wait.

apt-get install nitdroid-installer



# Run the installation nitdroid

nitdroid

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:

Code:

"/home/user/MyDocs/.nitdroid."

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:

Code:

#in  /boot/multiboot:

vmlinuz-2.6.28-omap1

vmlinuz-2.6.28.NIT.06



#in /lib/modules/

/2.6.28-omap1

/2.6.28.NIT.06

~current -> 2.6.28-omap1" 



#in /etc/multiboot.d

00-Maemo-2.6.28-omap1.item

11-NITDroid-mmcblk1p2-2.6.28.NIT.06.item

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:

Code:

# Get the root access

root



# To install almost everything You need

apt-get install kernel-power-settings

Y



# To install boot image to /boot and memu.item for multiboot

apt-get install kernel-power-bootimg

After installation You should have something like:

Code:

#in /boot

/multiboot

zImage-2.6.28.10-power47



#in /boot/multiboot

vmlinuz-2.6.28-omap1

vmlinuz-2.6.28.NIT.06



#in /lib/modules/

/2.6.28-omap1

/2.6.28.10-power47

/2.6.28.NIT.06

~current



#in /etc/multiboot.d

00-Maemo-2.6.28-omap1.item

01-Maemo-kernel-power-2.6.28.10-power47.item

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

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:

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

Code:

root

mount /dev/mmcblk1p2 /and

cd /home/user/MyDocs/.nitdroid

tar xvf oc-profile-500-700.tar

vi system/etc/power.conf

# In Vi press "a" to edit.

# Find  lines responsible for the frequency.

# Change to your frequency. By default, 500000-700000kHz

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
