You did not use the link with the title 'search' or 'power search'
http://talk.maemo.org/msearch.php
with your thread title (power kernel and multiboot) as keywords, did you?

Seems not.

Re: kernel power and multiboot
 

Multiboot is Depreciated and has little support due to it damaging NAND of the device.

Re: kernel power and multiboot
 

Hmm, I did not know that and maybe that's why I'm now in trouble... So I would like to ask for some help.
Details:
- I wanted to try out bfs kernel so I installed multiboot (I had omap1, kernel-power53 and bfs in /lib/modules) as that was the only way my n900 boot into that.
- I was using bfs but it did not work as espected so I uninstalled bfs kernel modules and bfs bootimg and installed backupmenu back which removed multiboot (since they conflicts).
- Now my device does not boot up...

What I was trying to do:
- Tried flashing the kernel (only the kernel; /lib/modules/current pointed to omap1),
- tried kernel-power zImage flashing (changed symlink for /lib/modules/cuurent to kernel-power53).

Neither succeded. I can start rescueOS and even chroot to maemo but cannot access to /home/opt and MyDocs even when trying to use mass-storage script (now I only have a windows laptop but it should not be a problem, is it...? anyway I will try with linux as well).

I have no other idea what I can do to avoid reflashing; not becuase of the process itself but I would like to access to some data...

Maybe someone can point me to the right direction?

Thanks is advance:

jm

Re: kernel power and multiboot
 

yeah...
that has been the singular reason I stopped playing with multiboot.
consequently I personally have no idea how you will work this out...
since I tried me darnedest to avoid the spot you are in justmemory :D
I am curious too now what a possible solution is...

Re: kernel power and multiboot
 

MyDocs and /home/opt "ususally" are
/dev/mmcblk0p1 and /dev/mmcblk0p2 and are on emmc and not nand.

Take out microsd card to have /dev/mmcblk0 point to emmc.

to access MyDocs content from freshly booted rescue os
you can do:

mkdir /tmp/MyDocs
mount /dev/mmcblk0p1 /tmp/MyDocs
ls /tmp/MyDocs

and for opt:

mkdir /tmp/opt
mount /dev/mmcblk0p1 /tmp/opt
ls /tmp/opt

Good Luck

Re: kernel power and multiboot
 

I still do have working multiboot and kernel-power and u-boot installed (but do not aske me how I managed ;) somehow manually years ago). :D

Normally you should be fine by linking /lib/modules/current to correct modules and flashing --kernel-only.

If you re-installed backupmenu: sounds like you had it before. So why not recover with an earlier made backup (before fiddling with system critical thingies)?

Re: kernel power and multiboot
 

So... Thank you all for your suggestions.

The thing is... It seems that I have to reflash it...
Linking and flashing kernel only simply does not work I do not know why.
It is not possible to mount these partitions ("No such file or directory") and Windows cannot so MyDocs and /home/opt with rescueOS mass storage mode - thank god I have a linux live cd (it sees these partitions) so at least I can save data.

Backupmenu simply does not work in this situation because it seeks for the kernel modules and cannot find those. The last backup I made is too old... (Yes I know I had to make a backup before this, but... I never learn... :) )

Thank you so much,

jm

Re: kernel power and multiboot
 

well...
small miracles...
it is some comfort you can save your data...
:)

Re: kernel power and multiboot
 

?

Of course you need to have the same version of kernel installed when using backupmenu to restore. So:
reflash
install backupmenu
install kernel version (matching your backup)
restore with backupmenu
done

--edit
or
reflash
install backupmenu
restore with backupmenu
flash --kernel-only (matching kernel version of your backup)
done

Re: kernel power and multiboot
 

OK I missunderstood your suggestion; for restoring it would work fine only thing is that my backup is old.

Sidenote:// It seems that the libc6 2.10 I made somehow prevents backupmenu to create a proper backup; it needs to be tested though...
