dockstar uboot upgrade: mtd0: Read-only file system after nanddump

Plan to upgrade uboot according to instructions: https://forum.doozan.com/read.php?3,12381

but can't use command in /usr/sbin directly, it shows" -bash: fw_printenv: command not found" after fw_printenv, need to /usr/sbin/fw_printenv, then

/usr/sbin/nanddump --noecc --omitoob -l 0x80000 -f mtd0 /dev/mtd0,

but it shows: mtd0: Read-only file system, how to fix this problem?

asterix,

I'm not clear what you asked. nanddump does not touch the mtd0 so that error "mtd0: Read-only file" does not make sense.

Please post the log of your attemp to install. Basically I need to see where you are running, from stock OS? and a few other info

dmesg
cat /proc/mtd

and then go ahead do the nanddump and flashing as instructed.

Please post everything.

You need to mount a USB drive and execute the command there. The mtd0 dump file will be saved to the USB drive which is r/w.

asterix,

Again, that's not enough info to see what the problem is.

(What daviddyer said above does not makes sense , either).

You are in either in stock OS or you are in the new Debian rootfs (since you can't boot with USB after "followed instruction: http://projects.doozan.com/debian/install_lenny.htm";)

Quote

> but it shows: mtd0: Read-only file
> system

That should occur only if you are in stock OS or a new Debian rootfs, and try to flash u-boot, or trying to set u-boot envs.

Please post the log of your attemp to install. Basically I need to see where you are running and what comamnds you are executing and what error messages are the result.

Well, I'm sure I'm correct...

He is still running the stock linux, his file system is in the flash and I think it is Read only.

I think he was running the command from his home directory as root

/usr/sbin/nanddump --noecc --omitoob -l 0x80000 -f mtd0 /dev/mtd0

but he won't be able to create the file "mtd0" in his home directory since the file system is read only.

That's why system complains "mtd0: Read-only file system"

A better idea would be changing the filename from "mtd0" to "mtd0.bin", in this way, we won't mess
the file mtd0 with partition mtd0

nanddump --noecc --omitoob -l 0x80000 -f mtd0.bin /dev/mtd0

I booted my dockstar into rescue system (2.8.2) and it has similar manner.

Since he needs to backup the mtd0, so I think he should mount a USB drive and run it from there.

@daviddyer,

> I think he was running the command from his home
> directory as root

Yes, you're absolutely correct! that was a confusing error message because of the dump file name.

> A better idea would be changing the filename from
> "mtd0" to "mtd0.bin", in this way, we won't mess
> the file mtd0 with partition mtd0

> Since he needs to backup the mtd0, so I think he should mount a USB drive and run it from there.

True. So assuming that the USB drive is mounted at /tmp/sda1, then,

cd /tmp/sda1
/usr/sbin/nanddump --noecc --omitoob -l 0x80000 -f mtd0.bin /dev/mtd0

The entire log of the session would have been better than us trying to verify what was the intent and where the error occured :)
