New install questions for edgerouter-lite-3

Hi, I have downloaded openwrt-23.05.2-octeon-generic-ubnt_edgerouter-lite-initramfs-kernel.bin
but cannot access the online help because of what looks like template/php errors.

My question is - is all that is required is to write the bin file to a usb stick and boot it?

edit: i'd also like to pre-set the ipaddress before firstboot as 192.168.1.1 is in use.
is this possible?

thanks

This page with instructions doesn't work for you?

The firmware is not distributed as a disk image. You will need to extract the sysupgrade.tar file and place the two files (kernel and rootfs) that it contains into two partitions on the flash drive. This only needs to be done once for the initial install. The sysupgrade scripts in OpenWrt will take care of upgrades.

I don't know if anyone has tried booting the initramfs then upgrading. That could in theory work without needing a Linux PC.

For a one-off case, rather than trying to make custom firmware it would be easier to boot the router first not connected to any network other than your PC then configure it.

That page didn't load the last time I tried it. I've loaded it now

I'd try both ways (boot with initramfs then upgrading) but I'd need to first give the kernel bin a different ip address

thanks

I booted Ubuntu from a USB and followed the instructions on the page and it went off without a hitch.

If you connect your computer to eth0 it will automatically be given an IP and the router is at 192.168.1 1

BUT I don't have an Internet connection and have yet to find a tutorial on how to set everything up

Anyone able to lend a hand?
