Re: How to mount opt folder?
Start rescueOS according to the documentation with the flasher utility, then
Code:
mmr It might be overkill for the removal to use the chroot, but ...?! |

Re: How to mount opt folder?
Always a good idea to power down the device, pull the battery, hold the power key for a couple of seconds, then restart the N900.
In rescueOS with mounted maemo rootfs get the info about the last running kernel Code:
ls -al /lib/modules/ Is a complete flashing of the fiasco image possible as a last hope? There was also some info buried deep in the forum to just flash rootfs, that could be extracted from the firmware/fiasco image. Did you ever make a backup with the built-in Backup application of your setting, contacts and stuff? |

I am sorry for a little delay in posting. Could you please precise if I must hold down power key without battery inside and if so - what it is the reason for that. Do you know what is the exact procedure of booting (that is - what NOLO is doing). And on which stage hardware is testing (if it is). Maybe my camera hardware is a problem - is there any way to test it under rescueOS? |

Re: How to mount opt folder?
Sorry for a few posts in a row. But maybe this will help you to diagnose my problem. So once again from my post #6 :
When I have run fsck I got a message: "The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device>". So is my filesystem correct? I do manage to mount home and opt folder so my eMMC is possibly OK. Although some time ago I have had a problems with USB port on my PC (not stable connection) so maybe something wrong happened during disconnecting myN900. |
Re: How to mount opt folder?
After executing command ls I get information as follows:
drwxr-x--- 1 root root 568 Jan 1 1970 2.6.37 Quote:

Re: How to mount opt folder?
It seems I have the kernel version 2.6.28. But to say the truth, I flashed the kernel and initfs already (using flasher 3.5). So kernel probably is not the reason of my problems. What about flashing NOLO? Is it safe? My NOLO enables flashing mode and initially starts device (NOKIA logo on the screen), but... who knows what is happening next?
And how to determine rootfs filesystem partition condition using fsck (or other command)? And, at last, how to find how much free space is left in rootfs partition? I had different values using command df. Maybe lack of space is the reason? |
Re: How to mount opt folder?
Rootfs does not need any fsck action, it is ubifs file system, that even supports unclean reboots. You could read about it here: http://www.linux-mtd.infradead.org/doc/ubifs.html .
The file system is like an archive that might be unpacked for rescueOS, but will show 100% full all the time in rescueOS. Nolo and kernel are flashed together, as far as i know, and you did that! Kernel modules are loaded by the kernel to load the different devices of the N900, that is why i suggest to check the modules directory. There is some knowledge about the boot process buried inside the forum or the wiki, @reinob did a real thorough investigation on the boot process here http://talk.maemo.org/showthread.php?t=87959 |
