Re: [Announce] Maemo5 running 32GB eMMC root FS (scripts)

egoshin, 009

Success - thanks for the guide. ( screenshot attached )
Initially on eMMC, very jerky and slow, with about 47 % RAM usage but loads of space, and I'm sure, as it settles in, it will speed up and smoothen out.
If you see anything wrong on the screenshot - please let me know.
And THANKS again.
FYI, the new scripts in post 125 work as advertised on 1.3 with Kernel-power46.
Also did the " mv /home/var/lib/gconf /var/lib/gconf.home
ln -s /mnt/initfs/var/lib/gconf.home /home/var/lib/gconf " script on UBIFS.

Re: [Announce] Maemo5 running 32GB eMMC root FS (scripts)

Congrats!
Egoshin's fine-tuning script does make a difference. With OC it feels even smoother than the factory setting.
btw are you using any bootloader or simply use egoshin's open-or-close-keyboard-booting-method? :D

Re: [Announce] Maemo5 running 32GB eMMC root FS (scripts)

Using the open/close method. open = eMMC, closed = UBIFS
Tried with multiboot - no luck, tried with bootmenu-n900 - no luck.
Tried every concieveable .item file configuration.

I will miss multiboot, as I had MER, UBUNTU, Meego, SHR and NITDroid running off SD's with multiboot - and also tried NITDroid on a partitioned eMMC - worked great - v.fast but got very hot !
Yip - the fine tuning script worked great on second reboot, the device is whistling along - faster and smoother than original !

Now to adding back all my applications - Queen Bee Widget and Fcron have revolutionised the way I use my n900, mainly saving 3-4 button presses per function, and automating functions, respectively !

Re: [Announce] Maemo5 running 32GB eMMC root FS (scripts)

Ya, multiboot and bootmenu-n900 don't work in this scenario. Next I am going to try kexec but first I have to get the right kernel image. AFAIK power-kernel supports kexec. :D
Thanks for mentioning Fcron. Haven't tried that yet but a couple of scripts look interesting... :D

Off topic. Also did some hacks today:
- Matan's modified-hildon-desktop, particularly the new task view (Ctrl-Backspace) which enables cycling windows.
- Remapping Fn-arrow keys and Shift-arrow keys
http://wiki.maemo.org/Remapping_keyboard -- say goodbye to the bulky toolbar in terminal.
- Cool stuff from http://wiki.maemo.org/User:Joerg_rw/tools
- Bash a la colorful terminal: http://talk.maemo.org/showthread.php?t=14613

Ah, forgot to mention something more relevant: installed a whole bunch of compilation tools (GCC, G++, etc.) right in the rootfs. Who cares about space? :D

PS @kashortie: how would you choose these: http://talk.maemo.org/showthread.php?t=66280 ? :D

Re: [Announce] Maemo5 running 32GB eMMC root FS (scripts)

009N

As well as the rootfs on eMMC and egoshins scripts mv /home/var/lib/gconf /var/lib/gconf.home
ln -s /mnt/initfs/var/lib/gconf.home /home/var/lib/gconf " UBIFS ....- I'm also now using swappolube with swappiness 30 etc...
O/C'd to 950... battery life up incredibly, as is the speed, and transitions - its SOOOO smooth !!! can multitask without the hanging - especially when browsing web, no more white screen hangs.

I'm also using MohammadAG thp/matan hildon-desktop tweaks, and manually modded with some osso/hilden-desktop bool true and int 1,2,3 etc http://my.arava.co.il/~matan/repo/Mo...n_Desktop.html to get CTRL+Backspace to scroll the nav tasks ( like windows/tab ) - NICE !
Scrolling is v.fast

I also using Fcam, and did a mod where the camera can use ext3 space when vfat full ...http://talk.maemo.org/showpost.php?p...1&postcount=66

cd /home/user
umount MyDocs
dd if=/dev/zero of=FAT bs=1M seek=256 count=0 # small 256MB image
losetup /dev/loop0 FAT
mkfs.vfat -F32 /dev/loop0
vi /etc/fstab # replace /dev/mmcblk0p2 with /dev/loop0
mount MyDocs
this works only till the next reboot.
Now we only need to modify the scripts (in ke-recv?) to do this automatically
and we could completey get rid of the VFAT partition

Re: [Announce] Maemo5 running 32GB eMMC root FS (scripts)

Scripts worked for me.

I got it to work with multiboot and stock kernel, but wouldn't work with kernel-power.

I used the stock scripts, with all the version checks commented out.
Then I installed bootmenu-n900, and edited /etc/bootmenu.conf just to test it. It worked.

I then installed nitdroid via the nitdroid-installer.

Then i did

Code:

apt-get install kernel-power-bootimg

apt-get install --reinstall multiboot-kernel-power

Then i copied the .item files and edited them (as seen below)

This works: 44-Maemo-2.6.28-omap1.item

Code:

 

ITEM_NAME="Maemo 2.6.28-omap1 home"

ITEM_KERNEL=2.6.28-omap1

ITEM_MODULES=ext3

ITEM_DEVICE=${INT_CARD}p2

ITEM_FSTYPE=ext3

And this works: 01-Maemo-kernel-power46.item

Code:

# AUTOGENERATED by multiboot-kernel-power

# !!! DON'T EDIT !!!

ITEM_NAME="Maemo kernel-power46"

ITEM_KERNEL="2.6.28.10power46"

ITEM_MODULES=ext3

This does not: 55-Maemo-kernel-power46.item

Code:

ITEM_NAME="Maemo kernel-power46 EMMC"

ITEM_KERNEL="2.6.28.10power46"

ITEM_MODULES=ext3

ITEM_DEVICE=${INT_CARD}p2

ITEM_FSTYPE=ext3

Maemo starts to load, I see the five throbbing dots for a few seconds, and then the device powers off.

I figured it was a watchdog thing, so I tried enabling RD mode, but RD mode appears not to work with multiboot.

Any ideas?

Re: [Announce] Maemo5 running 32GB eMMC root FS (scripts)

It is strange because at "five-dots" moment the DSME already setup communication with hildon-session and started feeding a watchdog. But I may be wrong (couple of months passed).

Let me look again on this. I have no power-kernel installed. Later I will ask you some questions but for now I like to get your /sbin/preinit, /bootmenu.sh and /etc/bootmenu.conf

Re: [Announce] Maemo5 running 32GB eMMC root FS (scripts)

/sbin/preinit
http://pastebin.com/w2VaFSeU

I'm using multiboot (which works with these scripts when not trying to boot kernel-power), so I doubt the bootmenu files are relevant. In fact, I don't even have a /bootmenu.sh or /etc/bootmenu.conf as the program is no longer installed.

I included the content of my .item files in /etc/multiboot.d/ in my previous post.

I know e-yes said this wouldn't work at all, but it does work when using stock kernel, and it almost works with kernel-power.

It needs patches for bootmenu-n900. I testing it now and later I publish my patches.

I tested it a lot and now it works fine without problem. It is good alternative solution to 009N. Scripts are hosted in my bzr branch on launchpad (from can be downloaded):

https://code.launchpad.net/~pali/+junk/maemo_M32GB

It only need lastest version of bootmenu-n900. Maemo5 is installed to /home/maemo5 so /opt is not shared with internal flash. It is now fully dualboot independent system with working bootmenu :)

For booting it use very ugly hack with overmount, pivot_root and chroot... but it works nice:

$ mount

Re: [Announce] Maemo5 running 32GB eMMC root FS (scripts)

Can anyone help me to modify this script to copy rootfs to SD Card instead of eMMC?
