First you have to get an Enc28j60, the following links may be usefull:

Next we will be soldering it on to the Hammer Carrier

We will use the 3.3V regulator of the Hammer Carrier, but you already need to have done the Hammer_How_to_Switching_5V_Regulator.


Wire the Olimex Enc28j60 board to the Hammer Carrier pins as follows:

ENC28J60 Pin Pin Hammer
SCK 1 7 SPICLK0
MOSI 2 6 MOSI0
MISO 3 5 MISO0
WOL 4 N/C
INT 5 8 EINT10
CLKOUT 6 N/C
CS 7 11 GPH0
RST 8 9 nReset
Ground 9 GND Ground
Vdd 10 TP9 +3.3V


Also make sure that your 5V main power supply can supply the Hammer as well as the ENC28J60-H.

I used a socket strip that keeps the board about 1/2 inch above the Hammer_Carrier prototype area. This may be important because the PIC chip on the ENC28j60 gets quite warm.

Software driver info:

The Good  Kernel SPI API
  The Bad  The 2.4 driver
    The Ugly  The current 2.6 "driver" included in the kernel patch at Hammer_Board_Software

The driver may either be compiled as a module, or as a part of the kernel. If you are running short on space for the kernel, it's probably advisable to compile it as module.

The SPI channel that is reserved for the ethernet on the Hammer Carrier board is SPI0. The MMC interface uses SPI1. The current UBE driver may need to be re-configured if you are going to use anything but the Hammer Carrier.
