Hi,

I have HW TP-link WR741ND v4 where flash was upgraded, currently 32Mb RAM and 16Mb Flash, this means after install dd-wrt in teory I should have at least 10Mb free.

So I would like to activate jffs in other to allow me to perform some customizations.

I went trought the wiki and forum but could not found a way to do it.

Any one can guide me?

Tried the Firmware Modification Kit.

Downloaded the firmware and extracted, then installed opkg and other ipk packs, build it back, now BIN have more than 4Mb, no issue was flash have 16Mb.

Flashed it to the router, all booted fine, but still not available the packdges I have installed neither found the correct way to activate jffs.

after some findings finally managed to cook it in a way that have the stuff I need there but I am missing some script or init line, probably for mounting.

As I can now activate the jffs from the Web but still not works, also appears in web "Total / Free Size(Not mounted)"

I just stumbled upon your post.

You are posting in the wrong forum

See:
To get the best out of DDWRT and the forum read these helpful pointers:

The TP link 741 NDv4 is listed in our database as 4 MB flash device, those do not have jffs2 compiled in

Hello,

Not sure why wrong place, in first port I refered a MOD to increase Flash from default 4Mb to 16Mb.

Also know default bin release don't have jffs2 compiled due the small size of rom (4Mb).


I just want to know if I can add the necessary using the MOD kit tool and what is necessary or if only building a specific bin.
