Hiya.

For those having problems installing due to the 'preinit' error :-
1 - install bootmenu
2 - run M32gbinit.sh
3 - replace contents of /etc/bootmenu.conf with this

Code:

# bootmenu customisation file
#
# included from bootmenu.sh after default menu is defined
# you can change some items or redefine menu completely

# timeout for automatic selection when no key is pressed
# set to -1 for no timeout (not recommended, can drain battery when device reboots unatteded)
MENU_TIMEOUT=30

# IP address for USB networking
USB_IP=192.168.2.15

# dim screen when in menu
#/usr/sbin/dsmetest -l 1 #for OS2006/7
#/usr/sbin/dsmetest -l 3 #for OS2008, 1 turns screen completely off

if [ -e /etc/bootmenu.d ]; then
# OK, rebuild menu from dynamic items
MENU_MIN=1 # first item index

MENU_1_NAME="Internal flash"
MENU_1_ID="flash"

MENU_2_NAME="Internal MMC card, partition 2, ext2"
MENU_2_ID="mmc2"
MENU_2_DEVICE="${INT_CARD}p2"
MENU_2_MODULES="mbcache ext2"
MENU_2_FSTYPE="ext2"
MENU_2_FSOPTIONS="noatime"
[ -d "/sys/block/${INT_CARD}/${MENU_2_DEVICE}" ] || MENU_2_NAME="(${MENU_2_NAME}) N/A"

menu_count=3
STR=`/usr/bin/find /etc/bootmenu.d/ -name \*.item`
if  [ ! -z "$STR" ]; then
	for bootmenu_item in /etc/bootmenu.d/*.item
	do
		ITEM_NAME=""
		ITEM_ID=""
		ITEM_DEVICE=""
		ITEM_MODULES=""
		ITEM_FSTYPE=""
		ITEM_FSOPTIONS=""
		ITEM_LINUXRC=""
		ITEM_FBMODE=""
		. $bootmenu_item
		let "menu_count += 1"
		eval MENU_${menu_count}_NAME=\$ITEM_NAME
		eval MENU_${menu_count}_ID=\$ITEM_ID
		eval MENU_${menu_count}_DEVICE=\$ITEM_DEVICE
		eval MENU_${menu_count}_MODULES=\$ITEM_MODULES
		eval MENU_${menu_count}_FSTYPE=\$ITEM_FSTYPE
		eval MENU_${menu_count}_FSOPTIONS=\$ITEM_FSOPTIONS
		eval MENU_${menu_count}_LINUXRC=\$ITEM_LINUXRC
		eval MENU_${menu_count}_FBMODE=\$ITEM_FBMODE
	done
	fi

let "menu_count += 1"
ITEM_NAME="Power off (when not on charger)"
ITEM_ID="off"
ITEM_DEVICE=""
ITEM_MODULES=""
ITEM_FSTYPE=""
ITEM_FSOPTIONS=""
ITEM_LINUXRC=""
ITEM_FBMODE=""
eval MENU_${menu_count}_NAME=\$ITEM_NAME
eval MENU_${menu_count}_ID=\$ITEM_ID
eval MENU_${menu_count}_DEVICE=\$ITEM_DEVICE
eval MENU_${menu_count}_MODULES=\$ITEM_MODULES
eval MENU_${menu_count}_FSTYPE=\$ITEM_FSTYPE
eval MENU_${menu_count}_FSOPTIONS=\$ITEM_FSOPTIONS
eval MENU_${menu_count}_LINUXRC=\$ITEM_LINUXRC
eval MENU_${menu_count}_FBMODE=\$ITEM_FBMODE
MENU_MAX=${menu_count}

fi

4 - Then reboot and you'll be able to choose booting from "Internal MMC card, partition 2".

One warning - don't try removing the original PR12 system - I've not tried it but I'm pretty sure the system will be unbootable and you'll need to reflash.

EDIT - to quickly check that you're really running on the eMMC - run conky and verify that root filesystem is same size as home (1.97Gb).

EDIT2 - Fixed a small bug in the script - booting from internal flash is now also presented as an option on boot.

Anyone have this working with multiboot yet? Can you share your .item substance I've not had a lot of time to muck with it and have failed getting it to boot a few times. Thanks!

Xopher,
Attached are the .item files from my n900 for Multiboot with Nitdroid, Power Kernel & Maemo PR1.2. I hope they are off assistance.
I changed the file extension from .item to .txt to upload, simply change it back after downloading them.

Thanks, I have those 3 items from my setup but was unsuccessful in creating an item for the eMMC boot. I only get the Nokia splash screen then a shutdown after some seconds. Might you have one for that?

Coffee | # 35 | 2010-08-01, 23:25 | Report

No mate, looking into it now.
After seeing the thread above for Bootmenu, our I expect will be very similar, so expecting something like (mix of the bootmenus & multiboots for stock kernel:

ITEM_NAME="Maemo 5 Internal Flash"
ITEM_KERNEL=2.6.28-omap1
ITEM_MODULES=mbcache ext2
ITEM_DEVICE=${INT_CARD}p2
ITEM_FSTYPE=ext2
ITEM_FSOPTIONS="noatime" [ -d "/sys/block/${INT_CARD}/${MENU_2_DEVICE}" ] ||

I did notice the bootmenu list FSTYPE as ext2 whilst the multiboot as ext3, not sure myself if correct.

Firstly,
Is this correct way to load the .sh file:
sh /home/user/MyDocs/M32GBinit.sh

So It ran and got the following:
Remove old Maemo 5 root files from /home before copying....
Umount /opt bindings (one error on /opt is expected)...
umount: cannot umount /opt: Device or resource busy
Start copying Maemo 5 root file system to /home....
(device can be unresponsible around 10 minutes)
Copying done.
Remount /opt back (error about / is expected)....
start: unkown job: pymaemo optify
Create dirs....
Edit a vital scripts on new root file system in /home partition...
Done: Maemo 5 (10.2010.19-1) has been prepared in /home partition.

Whilst it says done, are the above in red anything to worry about or normal and all part the process. How do I confirm that it has installed correctly?

xopher | # 37 | 2010-08-02, 01:08 | Report

do an ls on /home I believe

Well I tried this and doesn't work as it just skips back to boot menu. I do know that in Multiboot there are other files in home/boot/multiboot. I don't understand how Multiboot works and maybe we need other mods?

I tried the FSOPTIONS from the nitdroid and the ubuntu items I have and can not get it to boot either way. I never got the ubuntu one to boot either.I'll try loading it with Titan's kernel maybe

Coffee | # 40 | 2010-08-02, 01:38 | Report

Well I compared it against the list in the first thread:
/home/bin
/home/boot
/home/cdrom
/home/dev
/home/etc
/home/floppy
/home/initrd
/home/lib
/home/proc
/home/root
/home/sbin
/home/src
/home/sys
/home/syspart
/home/usr (usr - not user! /home/user is OK)
/home/var
/home/mnt
/home/tmp
/home/media
/home/home

All but one is different, I have an srv folder and not an src. Can you check what you have, maybe a typo?
As for the ".item" file, I have zero idea, have posted on the Multiboot thread and fingers crossed some kind lad will assist.
