jffs on wnr3500L V2

hello,

i can't auto mount jffs with the web gui

i have tried checking enable + rebbot the rooter nut nothing happens neither appears in the logs ?

 

Did you manage to mount it ? Is it possible manually via ssh or a script (command line) ?

Thank you

@Tathagata - tomato search

@Tathagata - tomato search jffs2 in mtd partition.

if (!mtd_getinfo("jffs2", &part, &size)) return;

but tomato for wnr3500Lv2 hasn`t jffs2 partition:
# cat /proc/mtd
dev: size erasesize name
mtd0: 00080000 00020000 "boot"
mtd1: 00180000 00020000 "nvram"
mtd2: 00040000 00020000 "board_data"
mtd3: 00040000 00020000 "POT1"
mtd4: 00040000 00020000 "POT2"
mtd5: 00040000 00020000 "T_Meter1"
mtd6: 00040000 00020000 "T_Meter2"
mtd7: 00040000 00020000 "ML1"
mtd8: 00040000 00020000 "ML2"
mtd9: 00040000 00020000 "ML3"
mtd10: 00040000 00020000 "ML4"
mtd11: 00040000 00020000 "ML5"
mtd12: 00040000 00020000 "ML6"
mtd13: 00040000 00020000 "ML7"
mtd14: 01b00000 00020000 "linux"
mtd15: 019eecd0 00020000 "rootfs"

As you think... can i rename one of partition (like ML7) to jffs2?

I have a couple of these devices lying around and am willing to do some testing once you have some working code.

Hi,

Hi,
Did someone manage to activate JFFS on tomato with this router ? With the shibby build, the menu item seems desactivated.
In the changelog of version 087 there is:
"- fix VLAN support for WNR3500Lv2 and remove JFFS support for this router"

Is this limited to shibby ?

Hey there,

Hey there,

have you managed to write the firmware with jffs support for WNR3500Lv2 ?

@Tathagata Das: Nice job if you are working on this. Thanks.

Sascha

It seems to be still

It seems to be still unsupported. I installed Tomato by Shibby for WNR3500Lv2 101-AIO few days ago on WNR3500Lv2 09/19/12
http://www.myopenrouter.com/download/list?sort=date&cat=75
It would make much sense to me to have it enabled, as router has 128MB so there would be no need to have optware installed on USB drive.

Thanks and regards,
Pawel Niewiadomski.

Could you (or someone from Netgear) please report on progress? It's been 8 months since the above statement was made...

As mentioned before I'm still

As mentioned before I'm still available to do testing. I have about 10 of these devices in my stock and around 45 running on customer sites. The only thing missing is JFFS :)

I would also be interested in

I would also be interested in this..

I have the most recent Tomato-by-shibby installed, and if there is free flash space I'd love to be able to make an ext3 fs on it to mount at /opt/

How can one tell which mtd blocks are currently in use and which are free?

First, I would like to thank

First, I would like to thank Shibby for his wonderful implementation of Tomato on the WRT3500Lv2.  I have been running it on my first wnr3500lv2 for several months, and I have been very happy with it.

To Tathagata Das: I appreciate the work you have done for the Open Source Community for Netgear.

But, and it it a BIG but...

Offering a router as Open Source (as stated on the box) is very misleading to the consumer, since the source code for the Broadcom networking components and other, JFFS and USB, is proprietary.  

The source code provided for dd-wrt and Shibby's Tomato contain code marked as confidential by Broadcom.  The developers at OpenWRT seem to be unwilling? to use code from proprietary sources(not suprisingly, due to copyright restrictions).

 By not utilizing JFFS within this platform,  as much as 120MB (Depends on the mtds utilized by the firmware) of the possible storage space cannot be realized.  

Until companies like Netgear push for more openess with regards to Broadcom's restrictive licensing of it's source code, a true open source platform will not be possible.

@Fred34563456:  You would not want to use ext3 directly on a flash chip, the superblock would wear out the flash.  A NAND flash chip has a limited number of writes to a single location.  JFFS, and most controllers in USB flash drives, levels the writes out to different locations on the chip, minimizing multiple writes to a single location, thus extending the life of the chip.

Well the main point was any

Well the main point was any read/write filesystem to allow installation of stuff like optware..

If JFFS is the way to go, then that would be fine.

Its not like it would be need to be written/modified very often anyway.

In fact, leaving it mounted RO there would be fine, so long as it could easily and quickly be remounted RW.

What are your thoughts on ext3 on usb flash drives? Would JFFS be better? I'm not really that familiar with it, can on just mkfs.jffs and mount it like anything else?

I was very much busy with R6300 and WNDR4500 releases. Once I get some time, I will look into this again.
