HOWTO: Change, remove or add u-boot on power kernel image - Page 4 - maemo.org

is there any other working uboot version??

EDIT: Just solved it using uboot in http://wiki.meego.com/ARM/N900/Insta...ge_for_flasher (ubooot.bin from link in point 7)

I don't see myself as an expert either regarding those things.
But I would compare it with Windows and Ubuntu for example. Windows has its own bootloader so does Ubuntu and Co...
Windows loads ntldr -> ntdetect.com -> boot.ini and Ubuntu get it's stuff sorted by grub. Booting both systems with just one bootloader doesn't work. Win needs ntldr and Ubuntu needs grub...
So all you can do is to combine these two.
That means you have to have both bootloaders installed and then two possibilities.
First booting Win bootloader and then pointing to grub for starting ubuntu or second booting grub and have it point to ntldr to start windows.

For N900; Meego needs u-boot and multiboot manages maemo, nitdroid and the others.

That's it. And because u-boot isn't needed for maemo it's not integrated by default in any kernels.

Sorry for not being able to explain in a more detailed way.

Did this solve the loading issue?

I would like to use the newest possible version of u-boot (for booting MeeGo off a different partition on my SD card) while keeping Kernel Power 48 (or Power 49 when it is in repos) How would I go about doing that?

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://bigbob.fun.free.fr/maemo-kernel-power/kernel-power_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

!!! :d

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
