Hello together,

i have a TL-WR1043ND router with OpenWrt Backfire 10.03.1 / LuCI 0.10.0 Release (0.10.0).

I want to install packagues like freeradius. So i need a JSSF2 NVRAM mount. I have installed with opkg nvram. How can I add this ram?

root@OpenWrt:/usr/sbin# nvram show
Could not open nvram! Possible reasons are:
        - No device found (/proc not mounted or no nvram present)
        - Insufficient permissions to open mtd device
        - Insufficient memory to complete operation
        - Memory mapping failed or not supported
   
Thx

The ar71xx architecture has no nvram.

oh i didn't know that. I have bought this router yesterday, beause this one has 8 MB NVram.
Do I need now a USB Stick for installing some packagues?

After installation openwrt uses free space of 8MB flash (about 5MB for your device) for emulation read/write filesystem. This allows to save changed/new files after reboot and to add packages. From this point of view openwrt has no nvram but normal filesystem.

The discussion might have continued from here.
