Tested on N950. i had to modify
its cool i haven't tested other os as yet thou.
the symlink on the folders so
then copy kernel into /mnt/boot/Harmattan/boot
note:my kernel was named openkernel i renamed it to 2.6.32.54-dfl61-20121301 if that matter..
then
which echoed
then edit /mnt/etc/boot.conf
to reflect what uname echoed
its cool i haven't tested other os as yet thou.
the symlink on the folders so
Code:
cd /mnt/boot rm -Rf Harmattan mkdir Harmattan cd Harmattan mkdir boot
note:my kernel was named openkernel i renamed it to 2.6.32.54-dfl61-20121301 if that matter..
then
Code:
uname -r
Code:
2.6.32.54-dfl61-20121301

Only when you boot up the device from the mnt4 partition and the init script mounts your "/dev/mmcblk0p2/" into "/mnt/2", then will the symlink "/boot/Harmattan->/mnt/2/" point to the real place, which is "/boot/" of your Harmattan root partition
Why I did it like this, I wanted to enable people to just create a /boot/ directory on the Harmattan rootfs, and copy kernel there instead of copying it on the ubiboot FS.
For functionality of course, it does not matter where you keep the kernels as long as they are somewhere where ubiboot kan see them
The important thing is to have the modules in the correct place for the booting 2nd level kernel to find them, which means "/lib/modules/" of the Harmattan root FS.

I have not encountered that kind of behaviour myself. Either the 2nd level kernel boots correctly or fails, and if it fails then it fails every time until the problem that causes it is corrected.
The Nokia logo does show, but it never gets to the pulsing animation when it'll decide to go rebooting.

However, for me there has never been any failures to boot, on non-patched kernels it just takes a bit longer.
I wonder if there is some installed application that theyosh has that might complain about longer boot time, which would then cause the failure.
It seems I need to put up a patched kernel to ubiboot page for people who do not want to compile it for themselves.

Again I choose the same OS, it starts. So it takes now two times to start. And the first time it stops at the point where the nokia logo should pulse / show the water drops.
dmesg output attached.
More tests tomorrow I think. Rebooting does take some time....

I have updated the README file to deal with the issue of L2 cache initialization in Harmattan boot.
The fix is to use the provided zImage_2.6.32.54-openmode_l2fix as the harmattan boot kernel. It is a module-compatible drop-in replacement for the vanilla aegis-neutered openmode kernel that has the L2 cache issue fixed. The patch is included as openmode_l2fix.patch
theyosh, please test your harmattan boot using the patched kernel.

Since it is necessary to flash the device with another kernel than the vanilla, also with these ones, ubiboot or l2fix patched, there are the usual OpenMode kernel bugs, like crashing when you install apps, etc..?

However, I think this is pretty advanced stuff, making it into a clickable install packet might encourage people to try it without understanding WHAT they are doing. Especially as you need to tune the "/etc/boot.conf" according to your available kernels. This way at least you need just a bit of command line knowledge to install it.
