How to mount opt folder? - Page 3 - maemo.org

NotMicro | # 21 | 2016-01-09, 17:05 | Report

Thank you very much for this useful post. Do you maybe know how to track process of booting? It could explain what is going wrong when my N900 starts. Maybe there is some log file created during startup ?

I forgot to write that I have had installed overclock profile (700 MHz) when failure took place.

Please try to get the information from your N900 via mounted rootfs and mounted optfs, but not chrooted

Code:

ls -al /mnt/maemo/lib/modules
ls -al /mnt/maemo/usr/share/kernel-power-settings

The output looks something like this from my running maemoOS, but yours should look similar

Again, it seems to be easier, and quicker, to remember the essential applications you had on your N900, but to clinch to vague clues, what might have gone wrong weeks ago. Get them from all over the net.

Could you please write how to make a copy of rootfs.
And second, very important thing - I cannot use apt-get install even if I chroot /mnt/maemo and mount home/opt folder.

Basically it is like this. Mount maemo rootfs, create mount point for storage partition, mount MyDocs partition to rescueOS, create archive of the rootfs on the MyDocs partition and enable mass-storage mode to transfer files and folders to your PC. Make sure the hidden dot-files and -folders are also transfered

Code:

mmr
mkdir /mnt/MyDocs
mount /dev/mmcblk0p1 /media
tar -c /mnt/maemo -f /media/rootfs.tar.gz
umount /media
ems

At last copy the content of both partitions to your PC. This saves the optfs partition, containing the /home/user and the /opt folders of the Maemo OS, and the MyDocs partition, containing your rootfs.tar archive, data and stuff.

Thank you for your last post, but I have 2 problems:

1. mmrt - "command not found"
2. mkdir /mnt/MyDocs - " mkdir : can't create directory '/mnt/MyDocs' : Read-only file system."

Could you help please.

michaaa62 | # 27 | 2016-01-10, 21:48 | Report

My bad!

First command must be mmr .
Second command will mount to /media.

I edited the former post http://talk.maemo.org/showpost.php?p...8&postcount=25 to have all the commands in one place!

Sorry, but I still have 2 problems:

1. When I execute mkdir /mnt/MyDocs I get a message "mkdir : can't create directory '/mnt/MyDocs' : Read-only file system.""

2. When I execute mount /dev/mmcblk0p1 /media I get a message "mount: mounting /dev/mmcblk0p1 on /media failed: Input/output error."

Help.

I am about to reflash whole device - that's why I want to backup rootfs. I have done it already in case of optfs (home, MyDocs).

But I want to try - for the last time - uninstalling fcam-drivers. When I use dpkg I still get a message indicating that fcam-drivers are installed and "connected" with blessn900. I can't though uninstall blessn900, as I described in post #4.

The first error is meaningless, the mount point will not get used.
Try this please for the second error

Code:

mount -t vfat /dev/mmcblk0p1 /media
