OpenWRT on OpenMesh

Docker based firmware build and flasher for the OpenWRT firmware and Open-Mesh hardware.

Using prebuilt docker image

docker pull ghcr.io/jw3/openwrt-openmesh:master

Building

After the build completes the firmware will be in /tmp:

ls /tmp | grep openwrt
openwrt-ar71xx-generic-om2p-squashfs-factory.bin
openwrt-ar71xx-generic-om2p-squashfs-sysupgrade.bin
openwrt-ar71xx-generic-uImage-lzma.bin
openwrt-ar71xx-generic-vmlinux.bin

The ap51-flash tool will be in /usr/local/bin

build.sh

usage: build.sh <git-ref> [image-name]

Flashing

Using docker image the command is formed like so (mind the network device id)

docker run --rm --privileged --network=host ghcr.io/jw3/openwrt-openmesh:master ap51-flash eth0 openwrt-ar71xx-generic-om2p-squashfs-factory.bin

Then plugin the OM2P in eth0 and power it up.

The output of the flash tool should look like this:

  [MA:C-:AD:DR:ES:S ]: type 'OM2P router' detected
  [MA:C-:AD:DR:ES:S ]: OM2P router: tftp client asks for 'fwupgrade.cfg', serving fwupgrade.cfg portion of: openwrt-ar71xx-generic-om2p-squashfs-factory.bin (1 blocks) ...
  [MA:C-:AD:DR:ES:S ]: OM2P router: tftp client asks for 'kernel', serving kernel portion of: openwrt-ar71xx-generic-om2p-squashfs-factory.bin (1993 blocks) ...

  [MA:C-:AD:DR:ES:S ]: OM2P router: image successfully transmitted - writing image to flash ...
  [MA:C-:AD:DR:ES:S ]: OM2P router: flash complete. Device ready to unplug.

Kill the container and reboot the device.

flash.sh

usage:flash.sh <eth-device> [tag]

Configuration

After flashing the following steps will prepare the router for use

• Connect via ssh ssh root@192.168.1.1
• Set the root password passwd
• Enable wifi uci set wireless.@wifi-device[0].disabled=0; uci commit wireless; wifi
• Switch pc connection to OpenWrt from ethernet to wifi
• Move ethernet connection from PC to WAN router
• Install the configuration webapp

opkg update
opkg install luci

or for ssl use luci-ssl

• Start webapp /etc/init.d/uhttpd start
• Start webapp on boot /etc/init.d/uhttpd enable
  • Access GUI at https://192.168.1.1

useful cli commands

• If the default 192.168.1.1 address conflicts with the wan router, change the om2p address
  • uci set network.lan.ipaddr='192.168.2.1'; uci commit wireless; wifi
• To enable dhcp on eth0 (this seemed to have been auto in the past)

uci set network.wwan=eth0; uci commit wireless
uci set network.wwan.proto='dhcp'; uci commit wireless

upgrades

The recommended way to upgrade is via the "sysupgrade" script. Just copy the factory image (openwrt-ar71xx-generic-om2p-squashfs-factory.bin) to the /tmp folder and run:

sysupgrade /tmp/openwrt-ar71xx-generic-om2p-squashfs-factory.bin

errors

• odhcpd-ipv6only
  • check_data_file_clashes: Package odhcpd-ipv6only wants to install file /openwrt/build_dir/target-mips_24kc_musl/root-ar71xx/etc/init.d/odhcpd But that file is already provided by package * odhcpd

history

Issue #42 in the mvf project tracked some original progress on this.

Initial development of this took place over in that repository.
