Want to add a folder in /jffs/ but it's in read only (Need JFFS expert)

[Kronyx]

Finally after all the resets and firmware update, the jffs is still in read only

A bit of a long shot, but have you tried mounting it manually?

mount -t jffs2 /dev/mtdblock4 /jffs

Another long shot, but if you follow the amtm Step-by-Step method here, do you have any success?

If not, where is it failing for you, specifically?

Here is the output:

Someone posted earlier today (or I read something old today) about mounting a usb stick as /jffs to avoid wear and tear or corrupt blocks. May be an alternative.

And to be doubly sure, you enabled step 2. Click 'Yes' to the 'Enable JFFS custom scripts and configs' option?

Then hit 'Apply' and then reboot the router?

If yes to all the above, then the router has a hardware fault.

Hopefully, just a simple step was missed and we're narrowing it down for you to have a working router.

Amtm can't install itself since his JFFS partition is not mountable.

Actually, looks like the flash_erase applet is there, so you could give this a try:

flash_erase -u -j /dev/mtd4 0 0

Yes both where selected.

It says command not found, i did a search and was not able to fid it.

kronyx@RT-AC3200-45F0:/tmp/home/root# flash_erase -u -j /dev/mtd4 0 0
-sh: flash_erase: not found
kronyx@RT-AC3200-45F0:/tmp/home/root# cd ..
kronyx@RT-AC3200-45F0:/# cd ..
kronyx@RT-AC3200-45F0:/# find -name flash
kronyx@RT-AC3200-45F0:/#

Have you tried flashing the firmware through Recovery Mode instead of through the router's web interface? (although I can't think why that would be any different)

No did not tried, it could be something to try !

kronyx@RT-AC3200-45F0:/tmp/home/root# flash_erase -u -j /dev/mtd4 0 0

kronyx@RT-AC3200-45F0:/# cd ..
kronyx@RT-AC3200-45F0:/# find -name flash
kronyx@RT-AC3200-45F0:/#

Could be model-specific then (I see the command is actually there on my RT-AX88U, not just a busybox applet).

 

[ColinTaylor]

kronyx@RT-AC3200-45F0:/# find -name flash

That command is wrong. It should have been:

find / -name flash_erase

I tried your's and still not found, i was already at the root / ;-)

Did you ever get this resolved? My AC3100 is having the same issue. Tried manually mounting the partition but got the same IO error as you.

I noticed my logging was complaining about a bad block, so, I'm thinking the NAND might be toast in my router. Everything else seems to work, however.
