yes, just make sure you are actually using it when copying :-)

No, anything you mounted by hand should be unmounted before reboot.

Re: Which OS is best suited for N770?

While doing /tar-temp/bin/tar ...., xterm died. dmesg has an error

Code:

Out of memory: kill process 1195 (osso-xterm) score 4586 and and children.

Out of memory: Killed process 1261 (sh)

/opt has only following dirs (bin dev etc lib lost+found mnt opt srv sys tmp usr var) where as /floppy has many more. So looks like tar didn't do it job fully. It is breaking somewhere in 'usr' dir as that appears last in 'ls -altr /opt/*'.

Or is there any solution to out of memory ?

EDIT:

Now my n770 is continuously rebooting. It asks fro for from where to boot, I select flash then it shows white screen and then reboots and ask for where to boot from and is in continuous loop. Looks like I screwed something. I will reflash it with original 49.2 image and start again :-(

Re: Which OS is best suited for N770?

Fanoush,

I flashed with original 49.2 image and it started boot fine. I re did everything (applications etc). I am currently cloning the system using /tar-temp/. I did skip initfs though.

Can I do the initfs

Code:

        # tar zxvf initfs_flasher.tgz

        # cd initfs_flasher/

        # ./initfs_flash

after I did cloning ?

Thanks.

Fanoush,

My tar died again. Here is dump of dmesg

Q1. Any idea how do I fix this ?
Q2. Can I do Initfs_flasher after doing tar ? (I want to make sure that I am able to clone the system before I make tablet as dula boot) ?

Note: I am running your kernel zImage-yuv420.

Thanks and appreciate all your help.

There is not enough free memory and oom-killer kills your xterm before the job is done. You may enable swap file or close unneeded applications. You may also try it over ssh so osso-xterm does not take memory. I'd start with enabling swap - control panel->Memory->Virtual. You may also just try second time in a row and hope oom killer will pick something else or memory is not that tight second time (strange but possible).

You can do it anytime it is not related to the cloning. It won't be much useful without system on mmc but it won't hurt.

As for the corrupted flash and reboot loop you mentioned - did you unmount both /floppy and /opt before reboot? Anything you mounted by hand should be unmounted before reboot.

Re: Which OS is best suited for N770?

Thanks fanoush,

First thing first. I enabled virtual memory to 64 MB and tar went fine. I booted from block 2 ext 2 and it boot just fine. Success at last. Thanks to your patiently answering my questions.

Q1. I saw following error in dmesg after tar was successful.

Code:

FAT: bogus number of reserved sectors

VFS: Can't find a valid FAT filesystem on dev mckblk0p

Q2. Do you know what it is ? Should I do anything about it ?

I did.

Q3. I didn't even give following command '# chroot /mnt/initfs cal-tool --set-root-device ask:mmc2' and still I am able to dual boot. Do I need to give command ? Or can I just forget it ?

Thanks.

Well each time I hope it is the last one and everything is clear so this helps me to stay calm and answer again ;-)

You tried to mount something as FAT filesystem but it is not FAT formatted. It is harmless.

It shows boot menu on each boot, sets mmc2 as default option and after timeout boots it automatically. It may be the best setup some people want.

Re: Which OS is best suited for N770?

Thank Fanoush for all your answers.

Re: Which OS is best suited for N770?

I forgot to run the initfs update before cloning the whole system, now i cannot boot into the mmc card. anything can be done to help? I'M thinking to reclone the /mnt/initfs directory only. any suggestions?Thanks.
