The Edimax BR-6104K/BR-6104KP is a router based on Infineon's ADM5120P SoC. The CPU has a MIPS32 core (little endian). These devices have 16MiB of RAM, 2MiB of flash memory, 2 USB ports (BR-6104KP), a WAN port, and 4 ethernet ports.
|Version/Model||S/N||OpenWrt Version Supported||Model Specific Notes|
|Rev. A||-||Backfire trunk||-|
|4Kc@175MHz/227MIPS||16MB||2MB||4 x 1||Yes||Yes||Yes|
Currently, the only way to install OpenWrt is to build Backfire and transfer the resulting image to the router via serial port. Please consult here (Midge). Here is a good HOWTO on installing a serial port.
The admswconfig tool configures the internal switch. Instead of using the tool manually, the switch can be configured using the "config switch" section in /etc/config/network.
Example: The following configuration separates WAN and LAN
#### VLAN configuration config switch option eth0 "1 2 3 4" option eth1 "0" option eth2 "" option eth3 "" option eth4 ""
The default network configuration is:
|Interface Name||Description||Default configuration|
|eth0||LAN ports (1 to 4)||None|
|eth1||WAN port (0)||DHCP|
Routers may come with identical MAC addresses, use "option macaddr " inside the /etc/config/network file to change the default MAC.
Numbers 1-4 are Ports 1-4 as labeled on the unit, number 0 is the Internet (WAN) on the unit.
The Edimax BR-6104KP has one reset button. The reset button is software controlled (/dev/switch), see http://www.agri-vision.nl/CMS/index.php?option=com_content&task=view&id=35&Itemid=63 for a script using the button.

The main PCB of BR-6104K with modifications. USB components were filled in and quick hack of +5V USB power supply added which virtually made it to work like BR-6104KP. Also the second serial port was connected to JP2 connector (no 3.3V to RS232 level converter shown).
On the BR6104K/KP board there is a 8pin connector called JP2 that can be used as serial port. You can connect a serial level shifter (such as the MAX232 family) to these pins.
Its pins are:
1.RX 2.+3.3V 3.nc 4.nc 5.nc 6.nc 7.TX 8.GND
Use the 3.3V as supply for the MAX chip, don't use the 5V from the USB. (You want to convert to the processors' levels, not the USBs')
ADM5120 supports MIPS EJTAG 2.6. Edimax 6104K/6104KP has standard 14-pin EJTAG header (unsoldered).
