OEM easy installation
The router can be upgraded using the default Sercomm edited bootloader by giving it a complete flash image (4MiB) with the bootloader included (although it won't be flashed) using the same windows utility used with the NSLU2. Upslug doesn't work due to some hardcoded parameters and my lack of familiarity with it, so I can't modify it to make it work. If somebody wants to help, it just needs to be modified to work with 4MiB images, without modifying the first 256KiB that contain the u-boot.
The process is this:
- Press the WPS button on top of the unit
- Connect power
- Two router leds should start blinking alternatively
- Start the program, press the “two arrows/refresh” button
- Click on the mac address, then file, then open the firmware image, then upgrade.
- The router will reboot automatically at the end of the upgrade process.
Upgrading OpenWrt
If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd or sysupgrade command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
LuCI Web Upgrade Process
- Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
- Upload image file for sysupgrade to LuCI
- Wait for reboot
Terminal Upgrade Process
- Login as root via SSH on 192.168.1.1
- Use the following commands to upgrade.
cd /tmp/ wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc
- If sysupgrade does not support this router, use the following commands.
cd /tmp/ wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot
Basic configuration
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
Specific Configuration
Interfaces
The default network configuration is:
| Interface Name | Description | Default configuration |
|---|---|---|
| br-lan | LAN & WiFi | 192.168.1.1/24 |
| vlan0 (eth0.0) | LAN ports (1 to 4) | None |
| vlan1 (eth0.1) | WAN port | DHCP |
| wl0 | WiFi | Disabled (cannot be enabled due to a RAM problem) |
Switch Ports (for VLANs)
The layout is WLLLL.
| Port | Switch port |
|---|---|
| Internet (WAN) | 0 |
| LAN 4 | 1 |
| LAN 3 | 2 |
| LAN 2 | 3 |
| LAN 1 | 4 |
Failsafe mode
The router can be put in Recovery/Update mode pressing the WPS button and connecting the power, then immediately releasing it. The procedure is successful if two leds start blinking alternatively
Buttons
→ hardware.button on howto use and configure the hardware button(s).
The device has only one button, WPS.

Opening the case
Note: This will void your warranty!
- To remove the cover unscrew two screws found under the rubber feets in the underside of the device.
Main PCB
Serial
→ port.serial general information about the serial port, serial port cable, etc.
Standard LVTTL 3.3V serial, 57600 8n1. RX connected _may_ hang the bootloader.
JTAG
→ port.jtag general information about the JTAG port, JTAG cable, etc.
There is no JTAG port on the device
Debricking
If the bootloader is working just use the Recovery method and flash a full firmware image.
Bootloader Notes
- The last 64KiB block in flash contains a signature (ascii eRcOmM) that is checked at every boot, if missing the router boots in recovery mode and the firmware needs to be flashed again to fix it.
Hardware mods
- as a beginner, you really should inform yourself about soldering in general and then obtain some practical experience!
32/64/128MiB RAM Mod
Just add/replace the ram chips with bigger 133MHz+ SDR SDRAM chips, the bootloader detects the size of the ram automatically. You can source those in SDR SDRAM SODIMM modules for a few bucks on eBay.
USB header
You'll need a USB Female receptacle.
Just connecting/soldering the wires DM/DP on pcb to the D-/D+ wires will give you an unpowered USB 2.0 Host. To add power you need to solder a LM1117 + 2 10u 6v + 2 1u 6v capacitors in the blanks at the back of the board.
Ext. Antenna
Buy 2 u-fl sockets on eBay and solder them in the appropriate spots in the PCB (where the antenna cables are soldered), then use them however you wish.

Notes
Still unsupported in trunk, WIP.
U-boot needs the kernel at 0x40000 instead of the standard ramips 0x50000.
0x0-0x3FFFF (uboot+env) and 0x3F0000-0x3FFFFF (eRcOmM sig) are reserved.
Boots a specific image build with WIP patches soon to be applied in trunk. Has problems with wifi and leds don't work because the GPIOs where they are are not known, plus they're unlabeled on the device itself and on the manual.
