Can't format JFFS2 on 3.0.0.4.374.41_0 / AC68R

[misteradrian]

First time trying out this firmware on my RT-AC68R. Installed 3.0.0.4.374.41 today and am trying to get JFFS2 working.

I see this in dmsg on boot:

Scanning device for bad blocks
Bad eraseblock 284 at 0x000002380000

Creating 2 MTD partitions on "brcmnand":
0x000002000000-0x000008000000 : "brcmnand"
0x000004000000-0x000006000000 : "jffs2"

I have tried this:

nvram unset jffs2_size
nvram set jffs2_format=1
nvram set jffs2_on=1
nvram commit

...and power cycled the router. Tried using "mtd-erase2" but that always just says "usage: mtd-erase2 [device]" ...

Looking through other posts some people mention random stuff like rebooted 20 times and it worked or went back to some specific firmware and it worked, but details are contradictory.

I tried this .. and it seems to work, but I'm afraid of doing something back like writing to the flash in some way it's not supposed to:

mount -t jffs2 mtd5 /jffs

Pointers would be great, thanks.

Interestingly after manually mounting the partition, it now automounts on reboots.

Now contains these files and directories:

admin@RT-AC68R:/jffs# ls -l
drwxr-xr-x 2 admin root 0 Dec 31 2010 configs
drwxr-xr-x 2 admin root 0 Dec 31 2010 scripts
-rw-rw-rw- 1 admin root 202095 Apr 25 16:27 syslog.log
-rw-rw-rw- 1 admin root 0 Apr 25 16:23 test

(I created the 'test' one myself when I first mounted it.)

Cool -- so I wonder why system.log is going to this partition? That doesn't seem smart to be filling it up with a continually growing file.
