Testing OpenWrt trunk@43949 local_patches on MLWG2 - gmacario/kingston-mlwg2-hack GitHub Wiki

Introduction

This page documents a few tests made on the OpenWrt image for the Kingston MWLG2.

Prerequisites

  • One Kingston MLWG2 device
  • Power supply for the MLWG2 (preferred before flashing the device)
  • The firmware image openwrt-ramips-mt7620-mlwg2-squashfs-sysupgrade.bin created as described in Rebuilding OpenWrt for MLWG2
  • A controlling PC
  • Ethernet cable
  • (Optional) A terminal emulator connected to MLWG2 serial console as described here.

Install the new OpenWrt image on the MWLG2

There are two cases here, depending whether the MLWG2 is running the stock firmware, or OpenWrt was already flashed to the device

Install the OpenWrt image on a stock MWLG2

You need to do it via BootLoader.

TODO

Upgrade the MLWG2 with the new OpenWrt image

If a previous OpenWrt image was already flashed on the MLWG2, you may easily upgrade the MLWG2 from OpenWrt itself.

Upgrade the MLWG2 with the new image (2015-01-12 18:05)

Power up MLWG2, wait until serial console shows

procd: - init complete -

From the PC browse LuCI (default: http://192.168.1.1/)

  • Username: root
  • Password: xxxx

LuCI: System > Backup / Flash Firmware

Flash new firmware image

  • Keep settings: Yes
  • Image: E:\temp\output-20150112-1805/openwrt-ramips-mt7620-mlwg2-squashfs-sysupgrade.bin

then select "Flash Firmware"

Flash Firmware - Verify

The flash image was uploaded. Below is the checksum and file size listed, compare them with the original file to ensure data integrity. Click "Proceed" below to start the flash procedure.

  • Checksum: c7a3fd5f50e8053160a71af58f864300
  • Size: 6.75 MB (15.38 MB available)
  • Configuration files will be kept.

OK, checksum matches ==> Select "Proceed"

Watch the serial console to make sure the new kernel is loaded when the MLWG2 reboots.

In case you requested to keep the original configuration, after a while LuCI will ask to login again:

  • Username: root
  • Password: xxx

Powered by LuCI patches Branch (git-15.011.60122-a850efc) OpenWrt Chaos Calmer r43949

OK, verified that the expected OpenWrt version (Chaos Chalmer r43949) is running.

From a PC let us log into the MWLG2

In our case we have restored our custom configuration

  • changed device IP to 192.168.64.90 (default IP is 192.168.1.1)
  • have also set root password (so telnet is disabled while SSH is enabled)

Test the MLWG2 with OpenWrt

Power up the MLWG2, wait until serial console shows

procd: - init complete -

From another PC, log into the MLWG2.

You may log into the MLWG2 via one of the following:

  1. Serial console (preferred): From the serial console, type "Enter"
  2. telnet (if no root password was configured in OpenWrt)
  3. ssh (if root password configured)

The default IP address for the Ethernet interface is 192.168.1.1.

Notice that you may use the uci command to reconfigure networking to take a free IP address of your local Ethernet.
