JFFS not mounting / read-only error

[mansoor]

Just FYI, I was facing the same issue and quite sure that I had a defective unit, but after quite a few reboots (definitely more than two!) and combinations of enabling/disabling the JFFS partition/format and hitting the apply button, it finally worked!

Same here, nothing changed, after a restart today JFFS started working!

yup

did the same..
and then just keep restarting while switching on/off the jffs (no reformatting)
after reboot 5 or 6 it started to work

In my case re-formats, mtd-erase -d jffs2, and reboots didn't help.
So I decided to build firmware and patch for my needs.

However after I uploaded my firmware to router I found that jffs mounted.
Then I reverted back to Merlin build and jffs it still works.

So probably updating firmware may fix issue.

The format issue on the AC66U was fixed in 266.23.

No jffs2 partition

Hi Guys,

Just got an RT-N66U, reset nvram, flashed it with RT-AC66U_3.0.0.3_178.15.trx and reset to factory from the UI.

I don't seem to get as far as others here with the jffs2 partition.

There is no mention of formatting in the syslog, and this is a small part of it:

Dec 31 12:00:08 kernel: Creating 4 MTD partitions on "Physically mapped flash":
Dec 31 12:00:08 kernel: 0x00000000-0x00040000 : "boot"
Dec 31 12:00:08 kernel: 0x00040000-0x01fe0000 : "linux"
Dec 31 12:00:08 kernel: 0x001713d8-0x01fe0000 : "rootfs"
Dec 31 12:00:08 kernel: 0x01fe0000-0x02000000 : "nvram"
Dec 31 12:00:08 kernel: Found an serial flash with 0 0KB blocks; total size 0MB

Running the format command gives the simpler error mentioned above:

admin@(none):/tmp/home/root# cat /proc/mtd
dev: size erasesize name
mtd0: 00040000 00020000 "boot"
mtd1: 01fa0000 00020000 "linux"
mtd2: 01e6ec28 00020000 "rootfs"
mtd3: 00020000 00020000 "nvram"
admin@(none):/tmp/home/root# mtd-erase -d jffs2

Error erasing MTD
admin@(none):/tmp/home/root#

Any ideas?

Thanks,

1) You flashed the firmware for a different router than what you have
2) You flashed a very old version.

Wowsers...! I must be blind or something... or just very late.
