I'm trying to set up NOCAT SPLASH on an E900 using dd-wrt.v24-18946_NEWD-2_K2.6_big-nv64k.bin
I've enabled NOCAT SPLASH and JFFS, but I can't create any folders inside the JFFS folder. The JFFS folder is read-only. I tried to change permissions on the folder using WinSCP but that doesn't work either.
LOM, is that true with the newer routers that have 16MB of memory over the 8MB like the e4200? If so then on the K2.6 version the STD_USB_NAS build would/could have the room for the JFF2, correct? _________________ Asus ac68r - DD-WRT v24-sp2 (4/9/15) - build 26653

I had 8MB flash based routers and E900 in mind when replying but it is true that 2-3 routers from each Asus, Cisco, and Netgear can run big or mega and at the same time have a huge jffs2 partition where you can install optware packages like UPnP-AV, miniDLNA, or similar in order to get the same functions that OEM firmware has included as standard.
An router with 8MB flash have room for a 7.6-7.7MB firmware so any build smaller than that have space for internal jffs2.
jffs2 requires 192KB for journalling + n blocks of 64KB for data, you can easily check the diff between mega and smaller build and calculate how big jffs2 size there is room for if flashing the smaller. _________________ You don’t really own a device until you can open it up and tear it apart

There is not enough free space in flash for jffs2 on the big and mega builds.
I'm having this problem as well. According to the webgui, I have 6,272.00 KB available. I'm using a mega v24sp2 (k26), build 18777 on an e3000.
I've cleaned it but it still ends up as read only and I can't change it any other way. Is there something missing here or is it truly too small for jffs?
jffs occupies "unused" flash space. your kb available, is nvram.. even though available, it is occupying flash space.. as well as kernel and cfe. Kernel = the firmware you flashed. _________________ [Moderator Deleted]
