I used squashfs, mainly because that's what the `prepare` command instructed me to use. I don't know why one would choose one over the other, perhaps someone more knowledgable could explain that. Here's what I did:
0. I reinstalled the BT firmware because I had an old and broken openWrt.
1. Copy the install image to a suitable directory on your computer.
2. Run `tftp` server to serve the install image (I used linux and used `tftp-hpa` launched with `sudo in.tftpd -L -s .` from the directory containing the install image).
3. Copy the firmware files you want to use to a USB drive and insert it into the router. I used `lede-lantiq-xrx200-BTHOMEHUBV5A-squashfs-sysupgrade.bin`
4. Connect serial terminal. Power on. Hit a key to stop boot. Then:
BTHOMEHUBV5A # set serverip 10.0.200.1
BTHOMEHUBV5A # set ipaddr 10.0.200.99
BTHOMEHUBV5A # tftpboot 0x81000000 lede-lantiq-xrx200-BTHOMEHUBV5A-installimage.bin; bootm 0x81000000
(note how I changed the IP of the router (`ipaddr`) to match my network and set the location of the tftp `serverip` rather than bending my network to fit the router's defaults.)
5. When booted:
root@lede:/# prepare
6. As per displayed instructions (note the inserted USB stick automounts at `/tmp/mounts/USB-A1` and I stored the firmware file in a `hh5a` directory - amend as appropriate) :
root@lede:/# sysupgrade /tmp/mounts/USB-A1/hh5a/lede-lantiq-xrx200-BTHOMEHUBV5A-squashfs-sysupgrade.bin
If it appears to hang for quite a while - hit enter to open the LEDE terminal.
7. Edit `/etc/config/network` for IP address and `/etc/init.d/network reload` (see below). Then log in using SSH.
8. Optionally, edit `/etc/config/wireless for Wifi and `wifi` to start it. Check from wireless device. Or do it later...
9. Set root password (with `passwd` on the command-line)
10. Reboot (enter `reboot` on the command-line).
Something I found useful was to set the homehub up on my network alongside my existing router whilst playing around. I added gateway and dns settings to the network config, which looks like this (where 10.0.0.138 is my existing router):
config interface 'lan'
option type 'bridge'
option ifname 'eth0.1'
option proto 'static'
option ipaddr '10.0.200.200'
option netmask '255.0.0.0'
option gateway '10.0.0.138'
option dns '10.0.0.138'
option ip6assign '60'
The base install doesn't include LuCi but it is easy to install with
root@LEDE:~# opkg update
root@LEDE:~# opkg install luci
No reboot required.
One other thing in case it is useful... here are my ADSL (not vdsl fibre) settings in `/etc/config/network`:
config dsl 'dsl'
option annex 'a'
option xfer_mode 'atm'
option line_mode 'adsl'
config interface 'wan'
option proto 'pppoa'
option username 'username@plusdsl.net'
option password 'password'
option vpi '0'
option vci '38'
option encaps 'vc'
option ipv6 '0'
config device 'wan_dev'
option name 'pppoa-wan'
option macaddr 'DE:AD:BE:EF:CA:FE'
You should already have similar blocks that you can edit to suit and they should already contain your device's mac address. Remember to `/etc/init.d/network reload` after changing `/etc/config/network`.
One thing I've noticed is that `halt` performs a reboot. I can't work out a clean way to shut it down.
