If you have EXACTLY the same content in item file, you won't be able to boot to Arch.
You should have this on your item file:
Then run u-boot-update-bootmenu again.

Anyway, try fsck-ing your Arch partition from Maemo to check any error on your Arch partition:

ok i will give that a try

it then give back invailid partition 4

why do i need to use partition 4 instead of 5

because when i do the steps of the guide itgive me this config file

ITEM_NAME="Arch Linux ARM (eMMC)"
ITEM_KERNEL="/boot/uImage"
ITEM_DEVICE="${INT_CARD}p5"
ITEM_FSTYPE="ext4"
ITEM_OMAPATAG="1"
ITEM_CMDLINE="root=/dev/mmcblk0p5 rootwait
init=/bin/systemdomapfb.vram=0:3M,1:3M,2:3M quiet"


and later on it lets you untar the root fs to mmcblk0p5
(root) mount /dev/mmcblk0p5 /mnt/ && cd /mnt
(root) wget ftp://bokmal.de/arch-n900/ArchLinuxA...-rootfs.tar.gz
(root) tar -zxvf

so someone can give me some guidence for where its gooing wrong

the guide i reverd to is here
http://blog.jakgibb.com/2013/03/28/a...stall-on-n900/

Because on your previous post, you write
From this information, it seems you want to install Arch on /dev/mmcblk0p5 (5th partition on you Internal MMC). Is it true?
If it is, then you should follow my previous post.
btw have you previously format /dev/mmcblk0p5 with mkfs.ext4?

yes thats what the guide on that site also does.

and yes i did that and i did it over agian bofore i worte this post its unpacking the root of to mmcblk0p5 as im writing this.

Could you give the output of this command:
# fdisk -l /dev/mmcblk0

---edit---
btw, in the tutorial, it has:
ITEM_CMDLINE="root=/dev/mmcblk0p5 rootwait init=/bin/systemdomapfb.vram=0:3M,1:3M,2:3M quiet"

when it should be:
ITEM_CMDLINE="root=/dev/mmcblk0p5 rootwait init=/bin/systemd omapfb.vram=0:3M,1:3M,2:3M quiet"

there is a space between systemd and omapfb

fdisk -l /dev/mmcblk0

last unknown is because device wasnt reset at moment of giving command

arch boor until the moment it wants to initial lize rx51 audio en and achip for bleutooth or something

Please reboot your phone and try this after reboot:
0. Move your Arch image to safe place, let say /home/user/MyDocs/tmp
1. Make sure /dev/mmcblk0p5 is set to linux partition (code: 83) and then format it
2. mount it to /mnt
3. tar Arch image to /mnt
4. edit your item file and run u-boot-update-bootmenu
put this in it:
Explanation of the above config:
ITEM_NAME="Arch Linux ARM" --> just label
ITEM_KERNEL="/boot/uImage"
--> Because you use absolute path, then this line will tell u-boot to look for uImage file on /boot folder in partition define on ITEM_DEVICE.
ITEM_DEVICE="${INT_CARD}p5" --> This line to u-boot to use internal card partition 5 as it new root (/) partition
ITEM_FSTYPE="ext4" --> tell u-boot that ITEM_DEVICE use ext4 file system
ITEM_OMAPATAG="1" --> I don't know
ITEM_CMDLINE="root=/dev/mmcblk1p5 rootwait init=/bin/systemd omapfb.vram=0:3M,1:3M,2:3M quiet"

@Pali, please correct me if my above explanation wrong.

Run u-boot-update-bootmenu
Make sure there is uImage in your Arch /boot partition:
If there is uImage file in /mnt/boot, then you should be able to boot to Arch.
