It's in the readpreviouspostsbeforeyouposthere repository. You have to enable it before browse any thread on tmo.

Here's a small guide to add u-boot to power48.

1st: Install all packages from 1st post

Code:

dpkg -i kernel-power_1:2.6.28-10power48_armel.deb
dpkg -i kernel-power-modules_1:2.6.28-10power48_armel.deb
dpkg -i kernel-power-headers_1:2.6.28-10power48_armel.deb
dpkg -i kernel-power-flasher_1:2.6.28-10power48_armel.deb
dpkg -i kernel-power-settings_0.12_armel.deb
dpkg -i kernel-power-bootimg_1:2.6.28-10power48_armel.deb

check if it's installed properly with

Code:

uname -r

Is should say 2.6.28.10-power48

Then follow up this little guide

(Thx to [DarkGUNMAN] and Fabry's guide of patching power-kernel with u-boot)

Open Terminal:

Code:

sudo gainroot
cd /home/user

# Prerequisites

Code:

apt-get install -y wget flasher mkimage

#1. Download power kernel deb file from repository and extract fiasco image from it

Code:

wget http://atrey.karlin.mff.cuni.cz/~pali/kernel-power_1:2.6.28-10power48_armel.deb -O kernel-power_2.6.28-10power48_armel.deb
dpkg --fsys-tarfile kernel-power_2.6.28-10power48_armel.deb | tar -xf - boot/zImage-2.6.28.10-power48.fiasco
mv boot/zImage-2.6.28.10-power48.fiasco /home/user/
rm -r boot
rm kernel-power_2.6.28-10power48_armel.deb

#2. Download Matan's u-boot from repository (it is named u-boot-for-power-kernel) and extract file image from it

Code:

wget http://repository.maemo.org/extras-devel/pool/fremantle/free/u/u-boot-for-power-kernel/u-boot-for-power-kernel_1.0_all.deb -O u-boot-for-power-kernel_1.0_all.deb
dpkg --fsys-tarfile u-boot-for-power-kernel_1.0_all.deb | tar -xf - ./usr/lib/u-boot/u-boot.bin.0x38000/u-boot.bin.0x38000
mv ./usr/lib/u-boot/u-boot.bin.0x38000/u-boot.bin.0x38000 /home/user/vmlinuz-2.6.28.10-power48
rm -r usr
rm u-boot-for-power-kernel_1.0_all.deb

#3. Unpack Fiasco image

Code:

flasher -u -F zImage-2.6.28.10-power48.fiasco
rm zImage-2.6.28.10-power48.fiasco

#4. Transform zImage in uImage (necessary because u-boot boots Kernel only in uImage file format)

Code:

mkimage -A arm -O linux -T kernel -C none -a 80008000 -e 80008000 -n "Power Kernel v48" -d zImage uImage

#5. Add power kernel uImage at end of previous file (starting write at offset 0x38000 aka 448 blocks)

Code:

dd if=uImage of=vmlinuz-2.6.28.10-power48 seek=448

#6. Remove zImage & uImage

Code:

rm zImage
rm uImage

#7.1 Flash the kernel

Code:

softupd -vv -s --local

#7.2 Open a new terminal (Shift+Ctrl+X) leave other xterm open!!!

Code:

flasher --local -f -k /home/user/vmlinuz-2.6.28.10-power48

#8. Optional - Multiboot - backup and replace Power48

Code:

mv /boot/zImage-2.6.28.10-power48 /boot/multiboot/vmlinuz-2.6.28.10-power48-bak
mv /boot/multiboot/vmlinuz-2.6.28.10-power48 /boot/multiboot/vmlinuz-2.6.28.10-power48-bak
mv /home/user/vmlinuz-2.6.28.10-power48 /boot/multiboot/vmlinuz-2.6.28.10-power48

#9. Optional - Clean Multiboot Entries
If you have old power47 or double power48 entries
open Filebox and navigate to /etc/multiboot.d to delete the respecting *.item files.

#10. Reboot and watch the

!!!

Edit: I coloured the code for those who don't know what goes together and what not. So, each colored lines are a complete string where to hit 'Enter' after. I left the obvious ones untouched

Greetz,

J4ZZ

when I had an N900 the only problem I noticed is that sometimes when recording a video the preview broke. am not sure why. it also corrupted the video files created. am not sure if this is the cause of the camera ui 2 or this update since I dont usually use video recording

Thanks J4ZZ,
i know the procedure, but if i get these lines right, we have to decompress the kernel image, put some files in it, compress it a little different, flash, tell the bootloader "hey, there's another kernel" and get it going. Very long procedure.
Well, i'm more into grub and lilo, but afaik it's quite easy to compile the kernel u-boot ready, or do I get this wrong? Could be, that this would make the kernel depend on u-boot, but I don't think this is a huge problem.
atm it's just easier to switch between v48 and the u-boot-ready v46 i think.
There will be further kernel updates and we would have to do this again and again.
I'd appreciate it, if non-geeks would be able to test meego to, write bugreports and such stuff...

Or could it be, that this u-boot or multiboot could be changed to "hey, look if there's a bootable OS on the sd card and boot it"? I did this sometimes on my laptop when I broke grub. I don't get why this is all so complicated - afaik the bootloader just points to vmlinuz and that's it - do I get this wrong?

This starts uboot - open keyboard boots from sdcard. Closed keyboard boots power48.
If multiboot is installed, slide keyboard open when you see Staring Kernel to show multiboot

First of all thanks Pali, sublime work! It works very well

Ok guys I wanna ask you a question that's been haunting me for weeks
Everyone knows that the enhaced open standard profile that iPods and almost every cellphone nowadays use for 3,5'' jack isn't actually bundled into the Maemo ecosystem, so you can't control the cellphone by wired remote neither talk by wired hands-free. Is this a software problem, that could be patched? Or is this a hardware limitation? If the first answer is yes, could this be patchable in a kernel release?
