Topic: Howto install OpenWRT on Ubiquiti Edge Router Lite ?

The content of this topic has been archived between 24 Apr 2018 and 29 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

The EdgeRouter Erlite has a removable USB drive, so some of the assumptions you might use for other routers are not the same here.

SquashFS is not useful because it's a removable USB drive, so there's no need to have a protected readonly image. It just adds complexity and takes up space.

JFFS is compressed, but the USB drive is 2gb so there's no need to have a compressed FS. When using this opkg cannot reliably know the free space.

Ext4 is the only other one that's supported and it makes the most sense. I am not particularly worried about flash wearing, in the worst case I can always replace the USB drive. If I'm particularly worried I can turn off journalling.

It's great to be able to take out the USB drive and plug it into my computer and read/write it.

It looks like in 15.05.01, this image exists:
openwrt-15.05.1-octeon-erlite-ext4-sysupgrade.tar

For some reason I have no option to build this for latest trunk sad

Option

That's a good option. Thank you! I'm building it now.

Something obviously got a bit screwed up in the latest trunk.

Incase you guys are interested, I wrote a comprehensive script (for MacOS) to deploy the ext image to the USB drive correctly. Partitions, Formats, Loads the Kernel & Root image.

I followed the instructions perfectly in the post: wiki.openwrt.org/toh/ubiquiti/edgerouter.lite

The original key or usb inserted the trunk version: openwrt-OCTEON-generic-ext4-sysupgrade.tar

I think I did a good job but unfortunately I get this serial output:
