EdgeRouter X-SFP disk space

Hi There

We installed OpenWrt for the first time yesterday. The basic functions are up and running. I would say the installation process was smooth. :slight_smile:

add system image http://openwrt.jaru.eu.org/openwrt-18.06/targets/ramips/mt7621/openwrt-18.06-snapshot-r7911-f65330d27d-ramips-mt7621-ubnt-erx-sfp-initramfs-factory.tar
show system image

There are some issues left.

  • Seems like the 256MB of flash memory is not available.
  • Lucy did not get installed.
  • We get a new SSH-key for every boot.


Does anyone see what is wrong?

Best regards

I'm not sure what instructions you followed, but on the ER-X, two installs are actually needed...the first is merely a bootstrap to get a very watered-down but operational version of OpenWRT installed, then you install 'real' OpenWRT on top of that.

Also note that snapshot builds do not include luci and it must be installed separately.


Now download the latest official 19.07 and install it with sysupgrade. This second install will build the flash filesystem.

Hi mk24 and rhester72

Thanks good for input. You are both right. I belived the install-process to be finished after the first install. All is good after the second install.

Best regards
