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

1st: Download and install all packages from here

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-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_1:2.6.28-10power48_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-power* /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 whose 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
