I don't understand what bugs you mean, I have been running my device always in open mode, (both PR1.2 and with PR1.3 since it came out) and I have never gotten my device crashed, not when installing anything nor ever else...

Can you point me to the cases when open mode has caused such problems?

Hi!

Did the previous step (/usr/sbin/flash_erase /dev/mtd4 0 0) succeed?
Are you doing this as root?

after a reboot it worked without error

EDIT: now i get this

Code:

~ # mount -t ubifs ubi0:var /mnt

mount: permission denied (are you root?)

this is the previous

Code:

~# /usr/sbin/ubiattach /dev/ubi_ctrl -p /dev/mtd4

~# mount -t ubifs ubi0:var /mnt

mount: permission denied (are you root?)

And you are trying that as root (devel-su) ?
Do you have something else already mounted at /mnt ?

Just do a command "mount" and see if there is some line that says something like "xxxx on /mnt/"

Re: Introducing ubiboot N9 (multiboot OS loader)

Fairly strange, that.

I tried several combinations, mounting with/without the ubi device attached etc, and only time that error happens is when you try to do it as user.
As root, it never gives that error.

Re: Introducing ubiboot N9 (multiboot OS loader)

One thing came to my mind... Yo said you booted the device at some point?

After you boot the device, you must attach the ubi device before mounting, sou you need to do this:

Code:

/usr/sbin/ubiattach /dev/ubi_ctrl -m 4

mount -t ubifs ubi0:var /mnt/

You never need to give the commands for flash_erase or ubimkvol again, but every time you want to mount it, you need to attach it before that.
