The Edimax BR is a family of a small broadband router. Some of them uses MIPS32-based SoC: ADM5120 or RTL8181 and runs MIPS Linux.

Devices

BR6104

The BR6104 is based on the ADM5106 SoC (ARM7TDMI) and Broad Net Technology real-time OS (SOHO.BIN).

BR6104K

The BR6104K is based on the ADM5120P (PQFP). It has one WAN Ethernet port and a 4 port LAN switch. The firmware contains the usual: Linux, Firewall, NAT, dhcp client and server, etc.

BR6104K is actually the same model as BR6104KP, but without USB connector, 48MHz oscillator e.t.c. soldered on the board, and without printer support in the firmware. It is possible to add missed USB parts and have a full BR6104KP model. The instructions are there. Edimax BR6104K/KP is rebranded Sweex LB000021 so PCBs are identical (PCB REV B. uses one DRAM chip, REV A two ones).

BR6104KP

The BR6104KP is the same as the BR6104K but has two USB 1.1 master ports that can be used to connect a printer and use it as a print server. Also you can use USB Flash disk for root filesystem (needed patch for usb root device).

BR6104P

The BR6104P is based on the ADM5106 ARM7 SoC.

BR6104S

The BR6104S is based on the Samsung ARM SoC.

BR6104W

The BR6104W is based on the ARM7 SoC.

BR6104WB

The BR6104WB is based on the Realtec RTL8181 SoC.

BR6104WG

The BR6104WG is based on the WavePlus WP3210 (125MHz MIPS R3000).

BR6104Wg

The BR6014Wg is based on the ADM5120 (BGA) and has one WAN port and 4 port LAN swith. Additionally, it has a WiFi 802.11G MiniPCI card: AirVast WN360g, which based on the Intersil / GlobespanVirata / Conexant PRISM GT chipset.

NMX-WB04G and ConceptronicC54BRS4 are clones of the BR6104Wg.

Routers's PCB has a place for the second MiniPCI slot, but socket is not soldered.

BR6104WP

The BR6104WP is based on ARM7 CPU.

EW-7207APg

The EW-7207APg Access Point uses ADM5120. It has a 5-port LAN swith and 802.11g interface.

Board seems to be the same as BR6104Wg with INPROCOMM IPN2220 mini-PCI card inserted.

Serial console is on J2 (Gnd, Tx, Rx) and 3.3V on J3. Pins must be soldered. 115200Bd 8N1

Adding a serial port

On the 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 familly) 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 wan't to convert to the processors' levels, not the USBs')

It is possible to use Siemens mobile phone datacable as converter. And its possible to use solutions like on the 3.3V TTL serial Port of the Linksys NSLU2

Set you terminals' speed to 115200 (8N1). When powering press SPACE three times to get into the boot menu.

(c) Exit                                                                       
                                                                               
Please enter your key :

Here you can choose to:

  • Upload new firmware to Flash (option a), this might be dangerous. Image must be with CSYS header.
  • Upload new vmlinuz to RAM (option b), nice for trying your own. Image must be usual vmlinuz.
  • Exit (option c), continue to load the vmlinuz already in Flash.

The uploading is done with the XModem protocol.

Tip: I experienced a lot of problems with the XModem transfers, which seemed to have something to do with the start of the transfer. For me, it helps to type some junk into the router, before starting up the XModem protocol. So I type "a" for upload to flash, then hold the arrow-up key for a couple of seconds, then start the transfer. However, this might be voodoo, your mileage may vary.

Linux support

Edimax recently released the sources to their kernel sources (2.4.18) and other tools such as Busybox.
