Prolink PWH2004

These units have 32M RAM, 8M flash, a serial port with pins marked on circuit board (CMOS level!), 4+1 LAN ports, 1xUSB port and 802.11n WLAN. The device is apparently also sold as Abocom WR5205.

Compiling firmware

Firmware can be compiled from "trunk":

  1. choose Ralink RT288x/RT305x as target
  2. and RT305x boards as subtarget.
  3. Network interface needs boot option board=…. (WiP)
  4. For WLAN, include rt2800-pci module under Wireless drivers.

The USB port does not appear to work yet (2010/09/12).
