Hi marmistrz,
yes 'ubiboot' is a big thing with some challenges.
As second kernel needs to be loaded from first kernel (with his root) from any location on any partition you need to specify the full partition path.
You gave full path inside your new rootfs only (/boot/kernel.name)
but you need to specify the partition also. And as juiceme (HUGE thanks to him, cannot stop to do so
) created it like OS names instead partition numbers, you will have to specify
/boot/Debian/boot/kernel.name

So the path should be in general:
shouldn't it?
Code:
/boot/$OS_NAME/boot/$KERNEL_NAME

Yes, if you got the new kernel to load in the new partition under '/boot'.
(default ubiboot assumption)
You may have that kernel anywhere. On any partition on any place.
But that mount points '/boot/$(OSNAME)/' should make it easier for not so experienced people (and make it harder for people like you
).

Working PVR drivers under 4.3.0-rc5:
https://www.dropbox.com/s/y6fnt79r6x..._2255.JPG?dl=0
I almost forgot how great glacier looks
As expected, some hacks are required: I had to change ubiboot parameters, and issue fbset in userspace, but the biggest obstacle seems problematic display panel drivers. I get warnings from kernel and "Framedone not received for 250ms!" after those warnings. I'll have to spend some more time to figure this one out...

On the other hand, I've just managed to boot the stock kernel on Debian (sort of). I mean: the system starts up, shows a black screen and dies. But it's still progress anyway.
So without a possibility of logging without hardware hacks I won't be able to do anything further. But, Filip, is your PVR ready to show me the boot log?

You can't use flasher to disable that, because ubiboot starts kicking both watchdogs (essentially starting them if flasher had set them not to be started automatically) - so something has to kick them until shutdown.

If you're interested I can post details on how to make serial cable without opening/damaging the device (that small cardboard piece with two wires sticking out in pictures is just inserted instead of SIM tray). - that might save you a lot of trouble.
Here is Nemo booting 4.3.0-rc5 captured with it: http://pastebin.com/raw.php?i=mZkmscN9 - as you see it's quite "informative"

There's one problem: the N950 doesn't have a SIM tray! One simply pushes the card inside the slot (and it's and ordinary SIM slot, just like the N900 one, not microSIM)
I'm not using 2.6. I'm using 4.3 from the start.

In any case on N950 dispaly panel is not the same as the one on N9 so I doubt that anything related to display would work with the patches I've made. I'll try to see if we can get USB to work and bring SSH into the game over USB. In the meantime you could try using 3.5 while we get 4.3 into shape.

And what about redirecting dmesg to a file? I can freely access the filesystem after the boot fails. This may be easier to do. Of course SSH is a much better way out, but this would be a temporary measure

finally found enough time to sit back and try booting the upstream kernel with DebiaN900 on N950.
This is the ubiboot.log (or rather its tail)
http://paste.ubuntu.com/12792793/
Notice one thing: although I specify partition 4 in ubiboot.conf (Debian is on /dev/mmcblk0p4), the log states
Still, I have absolutely no idea why it happens. Or maybe it's the default command line? Do you have any ideas?
