Cannot mount/format jffs on RT-AC68U fw. 3.0.0.4.374.34_2

I tried to mount / format JFFS on RT-AC68U. After reboot it's still unmounted.

It seems cannot format it durring boot.

I have tried to use mtd-erase but I'm getting this :

usage: mtd-erase2 [device]

Any help please ?

What makes you think it's unable to format? There is nothing in the log pieces you posted that relates to this in any way, this is just a list of found partitions during boot time.

 

[miodzicho]

Because in tools it says unmounted

That's not an erase issue then but a mount issue.

Post the result of these commands:

nvram get jffs2_format
nvram get jffs2_on

 

[miodzicho]

xxx@Hedgehog:/tmp/home/root# nvram get jffs2_format
0
xxx@Hedgehog:/tmp/home/root# nvram get jffs2_on
1

I did 2 or 3 reboots, and now seems it's mounted.

Try running the following commands to fully reinitialize jffs2:

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

I'm having the same problem on my RT-AC68u; I've tried multiple reboots and and the commands that Merlin posted to no avail; it seems to show jffs in dmesg but it never gets formatted it looks like:

Creating 2 MTD partitions on "brcmnand":
0x000002000000-0x000008000000 : "brcmnand"
0x000004000000-0x000006000000 : "jffs2"
VFS: Mounted root (squashfs filesystem) readonly on device 31:3.
devtmpfs: mounted

edit: Dropping back to RT-AC68U_3.0.0.4_374.38_2 from RT-AC68U_3.0.0.4_374.39_0.trx seems to fix the problem.

I am having the exact same issues.

I have tried both 38_2, and 39. Have followed all these steps and rebooted 20+ times.

Would love to see this resolved. Hoping to get a selective routing script configured.

Just a quick update.

Flashed .39 again and physically power cycled device. (Unplugged and waited 10 seconds)

jffs has now mounted properly.
